Polycarbonate labeling

Anyone thinking about using polycarbonate for roofing needs must comprehend polycarbonate labeling. Popular for its strength and ability to transmit light, polycarbonate has different labeling requirements that impact how well it works and what conditions it is appropriate for.

Usually, labels specify the kind of polycarbonate—solid or multiwall sheets, for example—as well as the uses for which they are designed. Because solid polycarbonate sheets are single-layered and have a high impact resistance, they are perfect for uses where strength and clarity are required, such as protective screens or safety glazing.

Multiwall polycarbonate sheets, on the other hand, are made up of several layers with air pockets in between. These sheets are ideal for applications like skylights or greenhouse roofing because they retain light transmission while offering exceptional insulating qualities.

Comprehending the labelling necessitates taking into account the polycarbonate sheets’ thickness. The gauge or thickness, which affects the strength and structural integrity of the sheet, is specified on labels in millimeters (mm). Although thicker sheets may be more expensive and need more support, they typically have better insulating qualities and a higher impact resistance.

UV protection is a critical component of polycarbonate labeling. Numerous polycarbonate sheets are treated to withstand UV light, which can otherwise result in deterioration and yellowing over time. UV protection level labels make it easier for customers to select sheets that will hold up over time in terms of performance and clarity, particularly for outdoor use.

Lastly, certifications or standards compliance may be mentioned on labels, signifying that the polycarbonate sheets satisfy particular quality and safety standards. Knowing about these certifications can help customers feel more confident about the product’s dependability and appropriateness for the purpose for which it is intended, be it industrial safety barriers, commercial skylights, or residential roofing.

Polycarbonate characteristics – properties of unique material

The most widely used material for work involving the glazing of buildings and other structures nowadays is polycarbonate. This is for understandable reasons. Because it is a synthetic polymer primarily composed of carbon, the properties of this special material far outweigh those of any other transparent analogue. Because of its properties, polycarbonate can be used in a wide range of industries, including trade, sports, entertainment, and agriculture. This sheet plastic is produced by industry in both cellular and monolithic forms.

Technical characteristics of polycarbonate

Phenol and carbonic acid combine to form the polymer plastic known as polycarbonate. In addition to being an environmentally friendly material, it possesses several technical qualities that make it adaptable to a wide range of finishing and construction tasks.

These qualities are as follows:

1. Size.
2. Weight.
3. Strength.
4. Transparency.
5. Thermal conductivity.
6. The radius of the bend.
7. The working temperature range.
8. Chemical stability.

Understanding polycarbonate’s technical properties is essential for organizing work toward a particular objective.

The industry produces polycarbonate products in single sizes, as per the standard.

The following are the ones for a cellular sheet:

• length – 300, 600 and 1200 cm;
• width – 210 cm;
• Thickness – 3, 3.5, 4, 6, 8, 10, 12, 16, 25, 32 and 40 mm.

Straight or x-shaped stiffness ribs are both possible. The sheet’s structure can consist of one, two, or three chambers. The material’s strength increases with the number of cameras.

The following signs are indicative of monolithic panels:

Wherever stronger glazing is required, quartz glass can be successfully substituted with monolithic polycarbonate.

When calculating structural elements like the foundation, support, and frame, it is necessary to take into account the specific gravity of glazing. This indicator, which is only 1.2 g/cm³ in polycarbonate, is two times less than in silicate glass. He has ten times more shock strength at the same moment.

A monolithic panel with 1 m2 weighs 1.2 kg. This material’s 3-mm panel, which weighs six times less than an 8-mm quartz glass panel, can effectively replace it.

Because the cell panels are so lightweight, there is essentially no pressure applied to the supporting structure.

According to thickness, the percentage of 1 m² of two-layer plastic is:

The panel measuring 2.1 by 12 meters can be easily calculated to weigh approximately 100 kg, even with its thickest thickness. This eliminates the need for loading equipment when working with it.

The polycarbonate panel’s greatest demand in many construction sectors can be attributed to its strength. He cannot break free and escape the blow due to the viscous nature of plastic. This is a very useful factor for seeing through places where people are situated. Elastic panels can only bend.

Among all transparent sheet materials available today, polycarbonate is the most resilient. Its strength is ten times greater than acrylic and two hundred times greater than glass. When the cell material is 6 mm thick, it can withstand hailstone blows without fear, and 10 mm monolithic plastic is bulletproof. In addition, he keeps his indicators the same in both extremely high and low temperatures.

This material’s ability to do the following allowed for the production of such products:

• windows in banks and offices;
• portholes of sea and aircraft;
• protective masks, helmets and glasses;
• glazing of sports, trade and educational institutions;
• transparent roofs;
• advertising shields;
• aquariums;
• durable visors and awnings;
• street plafones;
• protective partitions.

You can achieve matte and fully transparent structures by varying the colors and tinting techniques used.

Polymer panels can have any color and level of transparency because of how easily they are manufactured and the technologies that are employed. Depending on thickness, fully transparent materials allow in between 82% and 90% of natural light. The amount of dye added to the material determines how transparent it is.

By dispersing the sun’s rays, the mobile device enhances the lighting. By utilizing natural light during the day, we can save a lot of money when we use transparent roofing materials.

Every product meant for outdoor use has an ultraviolet protective coating applied to it. This helps to shield people and property from radiation while also extending the glazing’s useful life.

When sheets are bent to create curved structures, the material’s internal voltage is increased. As a result, the panel becomes more robust and stiff.

Polycarbonate has a much lower thermal conductivity than window glass because of its low internal density. Compared to a comparable product made of regular glass, the double-glazed window composed of monolithic plastic provides three times as much protection from heat and cold. Its strength will also be ten times greater.

Cellular polycarbonate serves as a soundproofing and thermal insulation material in addition to being aesthetically pleasing. The rooms are perfectly shielded from cold and noise by the air between its walls.

You can accomplish an extra effect by using tinted material, as the heat from the sun will cause it to warm the space.

Polycarbonate panels are frequently employed in the construction of arched and domed structures.

• visors;
• awnings;
• public transport stops;
• transitions over roads and railways;
• stalls, kiosks and pavilions.

For a given thickness of material, there is a minimum radius below which it can be bent. A reduction in this radius may result in the panel’s overvoltage and eventual failure.

These measurements apply to cell plastic and are as follows:

Polymers can be transported in a folded form thanks to their bending properties.

It is possible to bend monolithic polycarbonate with a minimum radius of:

The ability to bend makes cellular material suitable for glazing surfaces of different sizes and shapes.

The temperature range at which the machine operates

The operating temperature range of polycarbonate is -50º C to +120º C. This makes it suitable for construction in practically every climate zone in the nation. Significant changes in the size of the material occur when the temperature changes, either in a smaller or larger direction. For this reason, a change in plastic size of 3 cm per meter can result from a seasonal temperature difference of 70º C.

It is not combustible material. It melts in the event of a fire, releasing water vapor and carbon dioxide into the atmosphere. Polycarbonate burns when the temperature rises above + 5000 °C. Meeting such indicators is just not feasible in normal circumstances.

Plastic surfaces are not destroyed in a fire; instead, they become deformed and develop small holes. They allow warmth and smoke to escape, which helps put out a fire. Furthermore, plastic does not break into pieces that could harm humans.

Numerous materials can interact with polycarbonate without affecting quality standards.

It is therefore resistant to these materials:

• organic and synthetic oils;
• salt solutions;
• acids;
• oxidizing agents;
• soap and washing powder.

How to choose a polycarbonate

Modern technologies are responsible for the building materials market’s annual growth. The new polymer plastic, polycarbonate, has made it much simpler to create intricate translucent structures. It has every attribute required for this: strength, flexibility, light weight, light permeability, and good looks.

Polycarbonate is becoming more and more popular every day. Since supply follows demand, as you may know, there are a lot of products on the market from many different manufacturers. The suggested article will facilitate the decision-making process by providing the information required.

The best manufacturers of polycarbonate – which company to choose

Global leaders in the production of premium polycarbonate—European producers:

1. Plastics Made of Polygal

2. Makrolon (TM) by Bayer

4. Italian Polyu

These businesses produce goods that meet international standards.

Types of polycarbonate

Three types of polycarbonate exist: profiled, cellular, and monolithic (cast). Plastic is used for specific tasks depending on the kind of material and its technical properties (the density and thickness of the sheet, the quantity of jumpers and where they are located in cellular polycarbonate, etc.).

This is a single, continuous polymer sheet that ranges in thickness from 1 to 12 mm. It has no internal voids and has an exterior that resembles plexiglass or acrylic glass. Panels up to 20 mm thick are produced by certain manufacturers. Sheets come in a variety of colors and transparency and translucency levels, as well as colorless and reduced light permeability.

The polycarbonate produced by the casting process has a significant density and viscosity, which improves its resistance to mechanical loads. The impact viscosity of the polymer is 1000 kJ/m³.

The indicator’s multiplicity of excess when compared to other widely used materials for translucent structure construction:

Polycarbonate panels made of monolithic material are impervious to hail, powerful wind gusts, and heavy snowfall. The surface may fracture from extremely powerful blows, but many sharp, dangerous pieces that could cause injuries do not form.

The panel can be bent by giving them an arched shape if needed. The polycarbonate’s thickness determines the bending radius; the thinner the sheet, the smaller the radius.

Polycarbonate that is monolithic resists frost. The material can tolerate temperatures of up to 50 °C in the absence of mechanical loads, and it can also withstand shock loads at temperatures as low as -40 °C. Most brands have a heat resistance of +120 °C, and some have a heat resistance of up to +150 °C.

Polymer is used not only to create light spray structures but also to create noise- and shock-absorbing screens and interior design elements.

• High impact resistance;
• The ability to pass a large amount of sunlight (up to 90%);
• Small weight, simplifying transportation and installation;
• Simplicity of processing: sheets are cut without difficulty, sawn, drill;
• Resistance to temperature drops;
• Excellent heat and soundproofing qualities;
• The ability to block ultraviolet radiation thanks to a special protective layer;
• Moisture resistance;
• Fire resistance – the material melts, but does not burn;
• Safety in use;
• A variety of color shades, color stability.

• Instability to scratches (the leading world manufacturers have mastered the production of monolithic polycarbonate with anti -ababral coating, which protects the surface of the material from scratches and other damage);
• Technical solvents and acids leave stains on the surface;
• A significant degree of thermal expansion, which must be taken into account during the installation of the coating;
• High price.

These materials combine the characteristics of a translucent and ornamental fence, making them structural (bearing). It is widely used in residential construction for building fences, greenhouses, and roofing materials. It is related to different polycarbonate casting types.

Sheets with a trapezoidal or wave-like surface are thin—between 0.8 and 1.5 mm thick. Roofs made of profiled polycarbonate that are light, translucent, and transparent can support loads of up to 320 kg per square meter. He can substitute ondulin and corrugated board for roofing material.

The three categories of profile polycarbonate are color, degree of transparency, and wave size and shape. Colorless or colored materials can be transparent. Generally speaking, translucent panels are opaque, bright, and matte or smoky.

• It has all the qualities of monolithic polycarbonate, and stiffness ribs repeatedly increase its reliability with a relatively small thickness of the sheet;
• The strength is comparable to the strength of the metal corrugated board, while the weight of the material is several times less;
• Stability to corrosion;
• Light transmission up to 86%;
• Flexibility and ease of installation (can be used in arched structures);
• Resistance to fading;
• High soundproofing;
• Noiselessness (the sound of drops during the rain is not heard).

• Pretty high price;
• For fastening, it is necessary to use special thermal washers that guarantee reliable fastening of the sheet at temperature changes and humidity changes.

The most common variety of polycarbonate utilized in greenhouse construction. The material has a more intricate mechanism than earlier varieties; jumpers connect multiple plastic layers to give it rigidity. Simultaneously formed voids improve the material’s thermal insulation and noise reduction. Thickness of panel: 4–50 mm.

Multiple types of cellular polycarbonate are possible:

• Single -chamber – 2 sheets are connected by jumpers;
• Two -chamber – 3 sheets are connected by two rows of jumpers;
• Four -chamber – 5 sheets are connected by four rows of jumpers;
• Six -chamber – 7 sheets are connected by six rows of jumpers.

A 45-degree angle and perpendicular to the sheet’s surface are possible locations for stronger ribs, or jumpers. In contrast, the space between the jumpers varies, ranging from 5.7 mm in polycarbonate sheets with a single chamber to 25 mm in sheets with multiple layers.

Aerohel-filled honeycombs made of cellular polycarbonate are produced by certain manufacturers. It is more impact resistant and has a higher level of thermal insulation than triple-chamber double-glazed windows with argon to minimize heat losses.

• Excellent thermal insulation properties;
• Uniform scattering of the luminous flux, which favorably affects the growth of plants;
• Frost resistance;
• Available price relative to most plastics;
• Insignificant weight relative to glass;
• Safety in operation;
• High shock strength.

• Large sailing (it is important to ensure reliable fastening of panels during installation, otherwise strong gusts of wind will violate the integrity of the structure);
• In the process of installation, it is necessary to use special fasteners, since the material has a significant degree of thermal expansion;
• Instability in front of abrasives and solvents;
• High price.

Polycarbonate selection parameters

Given its potential applications, particular attention should be given to a number of the material’s fundamental qualities.

The density of polycarbonate determines its strength and resistance to the negative effects of the environment. It is crucial to keep in mind that excessive compaction decreases the material’s light transpartments and adds weight.

Monolithic sheets have an average density of 1.18–1.2 g/cm³. The density of the cell panels is between 0.52 and 0.82 g/cm³, although the sheet’s thickness stays constant and its weight fluctuates. The location of the internal jumpers as well as their thickness serve as different indicators of the density of cellular polycarbonate.

The arrangement of air channels and the density associated with them:

• Rectangular section-0.52-0.61 g/cm³;
• Square section-0.62-0.77 g/cm³;
• Hexagonal and triangular section-0.78-0.82 g/cm³.

The weight of one square meter of plastic is a significant quality indicator. Regardless of the type of polycarbonate, the weight of the sheet needs to match the material’s density on the panel’s surface. Since two sheets of the same thickness and air channel configuration can be produced using different amounts of raw materials, cellular polycarbonate should pay particular attention to this indicator.

The strength characteristics of a plate decrease with increasing ease of use, as does its ability to withstand wind and snow loads. You can lower the cost of the material by lowering the specific weight of the plate, but the quality suffers as a result.

Over the course of polycarbonate production history, different thicknesses have been developed for the traditional weight of 1 m² for sheets.

• 4 mm: cellular – 0.8 kg; monolithic – 4.8 kg;
• 6 mm: cellular – 1.3 kg; monolithic – 7.2 kg;
• 8 mm: cellular – 1.5 kg; monolithic – 9.6 kg;
• 10 mm: cellular – 1.7 kg; monolithic – 12 kg.

High-quality polycarbonate should weigh as near to these markers as feasible.

Defense against UV radiation

Plastic quickly loses its elasticity and its capacity to skip light when exposed to ultraviolet radiation. Without a protective layer, the panel degrades after two to three years in the street environment.

Since polycarbonate sheets are meant to be exposed to the elements, they need to be shielded from UV radiation.

Plastic is protected by manufacturers in one of three ways:

1. Volumetric protection: specific additives are mixed into raw material granules. This approach is insufficiently effective because dangerous radiation seeps through the sheet. A product’s service life is limited to ten years.

2. Film protection, or a thin, invisible layer of a unique coating that reflects the majority of light waves. 15–18 years of service life.

3. Volumetric filler combined with a double UV barrier layer: this technique ensures complete material protection and has a 25–30 year service life.

Sheets covered by the second and third methods are identified differently.

The information on the package can be used to draw conclusions about the level of protection. That being said, you can only trust the accuracy of the written word if a certificate attesting to its veracity exists.

Consider the minimum bending radius of a particular type of polycarbonate when choosing materials for an arched greenhouse or a design with curved elements. The radius of the bend ranges from 0.6 to 2.8 m, depending on the kind of material and leaf thickness.

It is important to pay attention to these details when installing the panels because excessive bending can harm the polymer’s internal structure and protective UV layer. Damage will therefore shorten the structure’s service life.

Transmittance of color and light

These are crucial material properties because, when the greenhouse is covered, they affect the temperature and lighting levels inside. The color, level of transparency, and thickness of a polycarbonate sheet determine how much light it can block.

Which polycarbonate to choose

The material must be chosen with consideration for the intended use and architectural characteristics of the structure in which the installation will be done. You must buy UV-protective materials for any street building. You can buy polycarbonate without UV protection for ephemeral outdoor structures that are meant to last one or two seasons.

Greenhouses are organized using cellular polycarbonate, which is transparent and colorless. Overly large amounts of light (between 25 and 50%) are absorbed and dispersed by excessively thick sheets (defined as having a thickness of more than 10 mm). Plant growth will be negatively impacted, and productivity will decline.

The thin panel will not help to keep the greenhouse at its ideal temperature. It is advised to use material that is 4, 6, or 8 mm thick. The climatic zone where the greenhouse design and the presence of a heating system will be erected are taken into consideration when choosing the thickness and density of the material.

Cellular panels with a thickness of 6–8 mm can be used to create a practical and useful canopy without any designer extras. With monolithic or profiled polycarbonate, an amazing visual appeal can be combined with functionality to create a design that is truly remarkable. Kovanina and other flexible materials go well together with metal and wood.

3. For roofing and fencing

You can construct a fence out of any type of polycarbonate. The use of translucent panels will give the location a unique, cozy feel.

When building fences and roofs, profiled translucent sheets in a bronze color are frequently used. This material’s decoration of the building elements blends in beautifully with the surroundings. A material with a wave height of no more than 15 mm is chosen for a pitched roof.

How much is polycarbonate

The brand, kind of polycarbonate, thickness, sheet size, color, and other factors—like UV protection—all affect the material’s cost.

1. Typically, producers use low-quality raw materials, such as secondary or married materials, as well as their own production waste, to create inexpensive goods.

2. The "light" or "lightweight" cellular polycarbonate type also denotes a lower price, but this material will only last 2-4 years because the 3-3.5 mm panel’s thickness is not intended for the snow and wind loads that Russian greenhouse buildings encounter.

3. The cost of premium cellular polycarbonate with a thickness of 4 mm ranges from 200–280 rubles per 1 m2, while that of 6 mm is between 350 and 450 rubles, and that of 8 mm is between 430 and 550 rubles. Keep in mind that the material is sold in sheets measuring 6.3 m², 12.6 m², and 25.2 m².

4. The cost per 1 m² of domestic monolithic polycarbonate (with a sheet area of approximately 6.3 m²) with a thickness of 1.5 to 3 mm, ranging from 530 to 1,400 rubles; 4 to 6 mm thick, ranging from 1450 to 2400 rubles; and 8 to 12 mm, ranging from 2850 to 4500 rubles.

5. The cost per square meter of profiled polycarbonate, which ranges from 500 to 1100 rubles.

The top producers of polycarbonate. variations of the suggested material, as well as its benefits and drawbacks. factors to consider when selecting a material. suggestions regarding the selection of polycarbonate.

Comprehending polycarbonate labeling is essential for both consumers and builders when it comes to roofing materials. The selection of polycarbonate sheets that fulfill particular performance requirements and durability expectations is ensured by clear and accurate labeling. The label gives important details about how well the material will function in various situations, such as UV resistance, impact strength, and fire rating. With this information, consumers are better equipped to choose the polycarbonate sheets that best meet their needs, whether they are for commercial or residential roofing projects.

Technical characteristics of cellular polycarbonate

Buildings and other structures are frequently constructed using polymeric materials for a variety of uses. A panel made of two or three layers of cellular polycarbonate has longitudinal stiffeners positioned in between them. With a relatively small specific grade, the sheet’s high mechanical strength is attributed to its cellular structure. Examine the properties and parameters of cellular polycarbonate in greater detail in order to fully comprehend all of its technical features.

What is cellular polycarbonate

The name of the material comes from the sheet’s resemblance in cross section to a rectangular or triangular cell. Granular polycarbonate, which is created when carbon acid polyester and dihydroxide compounds condense, is his raw material. Polymer is a thermoreactive plastic that possesses several special qualities.

Extrusion technology is used in the industrial production of cellular polycarbonate from granular raw materials. Production is conducted in compliance with Tu-2256-001-54141872-2006 technical specifications. In our nation, the aforementioned document serves as a guide for material certification as well.

The panels’ primary specifications and linear dimensions must adhere strictly to the standards’ requirements.

There are two possible types of cellular polycarbonate structures during the transverse section:

The structure of its released sheets is as follows:

2H: rectangular cells in a two-layer structure.

Three-layer construction known as 3x combines additional inclined partitions with rectangular cells.

3H-Three-layer sheets with a 6, 8, or 10 mm thickness are made using a rectangular honeycomb structure.

5W, or five-layer sheets, typically have a thickness of 16 to 20 mm and a rectangular honeycomb structure.

5x – five-layer sheets with straight and angled ribs are released at a thickness of 25 mm.

Temperature modes of use of cellular polycarbonate

The resistance of cellular polycarbonate to unfavorable environmental conditions is very high. The type of material used, the standard of the raw materials used, and adherence to production technology all have a direct impact on the operating temperature conditions. This indicator ranges for the great majority of panels from – 40 °C to + 130 °C.

Certain varieties of polycarbonate can tolerate temperatures as low as -100 °C without losing their structural integrity. The material’s linear size changes with temperature. This material’s linear thermal expansion coefficient, which was calculated using standard DIN 53752, is 0.0065 mm/m-°C. Cellular cells can expand up to 3 mm per m in both length and width of the sheet, but this is the maximum that is allowed. As can be observed, polycarbonate expands significantly when heated, so proper gaps must be left when installing it.

Cellular polycarbonate’s linear dimensions vary with the outside temperature.

Chemical resistance of the material

Decorative panels are subjected to a multitude of damaging elements. The majority of chemically inert substances and compounds are relatively resistant to cellular polycarbonate.

It is not advised to use sheets in contact with the following materials:

1. Concrete and cement blends.

2. Plasticized PVC.

3. Pesticide-infused aerosols.

4. Important cleaning products.

5. Acetic acid, alkalis, and sealants based on ammonia.

6. Solvents with halogen and aromatics.

7. Methylene alcohol solutions.

The following substances are highly resistant to polycarbonate’s chemical resistance:

1. Mineral acids concentrated.

2. Alkaline and neutral salt solutions.

3. The majority of oxidizing agents and restorer types.

4. Alcoholic solutions—apart from methanol.

Silicone sealants, as well as those specifically made for them, are EPDM and analogous sealing components when it comes to sheet installation.

Mechanical strength of cellular polycarbonate

The cellular structure of the panels allows them to bear heavy loads. Furthermore, extended contact with small particles of the sand type can cause abrasive effects on the sheet’s surface. When sufficiently hard materials come into contact with one another, scratches may form.

The brand and structure of the material have a significant impact on the polycarbonate’s mechanical strength indicators.

The panels’ testing process produced the following outcomes:

Cellular polycarbonate is inspected for strength indicators in compliance with ISO 9001: 9002 standards. With proper sheet installation and the use of special fasteners, the manufacturer guarantees the preservation of operational characteristics for a minimum of five years.

Leaf thickness and share

Production technology makes it possible to produce various sizes of cellular polycarbonate. At the moment, the industry produces panels with varying internal structures that range in thickness from 4, 6, 8, 10, 16, 20, and 25 mm. Polycarbonate has a density of 1.2 kg/m3, as established by the DIN 53479 standard’s measurement procedure.

The resistance of cellular polycarbonate to ultraviolet radiation

The properties of cellular polycarbonate can offer trustworthy defense against harmful UV radiation. In order to accomplish this effect on the sheet’s surface during the production process, the co-sector applies a layer of a unique stabilizing coating. Providing technology ensures that the material will last at least 10 years.

In this instance, the polymer’s fusion with the basis prevents the protective coating from peeling off during operation. Make sure you check the markings carefully and align the sheet correctly before installing it. It is time to turn out the coating that provides UV protection. Depending on the color of the panel, its light transmission can range from 83% to 90% for unpainted sheets. Colored transparent panels allow only 65% of light to pass through, while light that does pass through them is perfectly dispersed by polycarbonate.

Thermal insulating properties of cellular polycarbonate

Cellular polycarbonate has very decent thermal insulation characteristics. Moreover, the heat of the resistance of this material is achieved not only due to the fact that it contains air inside, but also because the material itself has a large heat resistance than glass or PMMA of the same thickness. The heat transfer coefficient, which characterizes the thermal insulating properties of the material, depends on the thickness and structure of the sheet. It ranges from 4.1 W/(m² · K) (for 4 mm) up to 1.4 W/(m² · K) (for 32 mm). Cellular polycarbonate is the most acceptable material, where you need to combine transparency and high thermal insulation. That is why this material has become so popular in the production of greenhouses.

Industrial polycarbonate greenhouse.

Fire characteristics

Polycarbonate cells are resilient to the effects of elevated temperatures. This material falls into category B1, which is classified as difficult and self-adjusting by the European Union. Polycarbonate does not release harmful or poisonous fumes when it burns, neither to humans nor to animals.

The structure of the object and the creation of through holes are destroyed by the effects of high temperatures and open flames. The material is taken out of the heating source and has its area drastically decreased. The formation of holes allows combustion products and excess heat to be removed from the fire’s focus.

Lifetime

Cellular polycarbonate manufacturers guarantee that the material’s primary technical properties will remain intact for a maximum of ten years, as long as installation and maintenance guidelines are followed. The sheet is protected from ultraviolet light by a unique coating on its outer surface. Its damage causes the panel to prematurely destroy itself and drastically shortens its service life.

Noise insulation

The low acoustic permeability of polycarbonate is attributed to its cellular structure. The panels’ noticeable soundproofing qualities are directly influenced by the kind of sheet and how it is constructed inside. A minimum thickness of 16mm for multilayer cellular polycarbonate guarantees the extinction of sound waves within the 10-21 dB range.

Moisture resistance

This sheet material is essential for roofing because it is impermeable and does not absorb moisture. The primary challenge in the water-cell polycarbonate interaction is getting through the panel. It is nearly impossible to remove without dismantling existing structures.

Honeycombs that have been exposed to prolonged moisture may bloom and eventually disintegrate.

During the installation process, only specific fasteners with sealing elements should be used in order to prevent such a development of events. A unique ribbon is used to glue the edges of polycarbonate. Using compressed air from a cylinder or compressor to clear the honeycomb is the simplest method of cleaning them.

In order to shield the edges from moisture, 1. A unique adhesive tape; 2. a unique profile intended to be placed over the tape.

The color scheme of panels

The market is supplied with cellular polycarbonate in both painted and transparent forms.

Manufacturers provide the following color panels to consumers:

Additionally, there is a silver panel version that is totally opaque. Cellular polycarbonate’s light permeability is contingent upon both its internal structure and thickness. Light transmission for transparent materials ranges from 86% for 4 mm sheets to 82% for 16 mm sheets. The material is colored in an array, which contributes to the color’s preservation over the course of its service life.

Purpose and scope of application of material

The primary applications of cellular polycarbonate in construction are in the building of roofs and enclosed structures.

Because of its remarkable qualities, this material is being utilized more and more in the production of the following components:

1. Structures with arches

2. Leaning over the front entrance

3. Bus stops

4. Sunny driving conditions

5. Sound-absorbing barriers placed beside high-speed highways and railroad tracks

These panels are used in private homes to glaze summer kitchens, verandas, attics, and arbors. The construction of agricultural greenhouses with varying levels of durability is another application for solar panels.

The complexity of the installation of cellular polycarbonate

Cellular polycarbonate is installed by bolting it to a frame made of aluminum or steel profile. Bending the sheets over the stiffeners is permitted; this feature is frequently employed in the production of roofs and visors. The panel’s minimum radius of rounding is inversely correlated with its thickness. It is impossible to bend 25 mm thick cellular polycarbonate.

There are several guidelines that must be followed when installing something.

1. To cut panels up to 10 mm thick, use a saw with small teeth and a sharpened knife.

2. Drilling is done using a drill that is at least 40 mm away from the edge.

3. Self-cutting screws with sealing washers hold the panels to the frame.

4. Using unique connecting elements, separate sheets are joined together.

We will go into great detail about the exceptional technical properties of cellular polycarbonate, which are contributing to its increasing use in our nation.

Anyone thinking about using polycarbonate in roofing projects needs to understand labeling. Specifications regarding polycarbonate sheets’ thickness, UV protection, impact resistance, and fire rating are frequently found on their labels. These labels offer crucial details that assist customers in choosing the best kind of polycarbonate for their particular requirements.

The strength and durability of polycarbonate sheets are directly impacted by their thickness, which is commonly expressed in millimeters (mm). Better insulating qualities and increased impact resistance are typically found in thicker sheets. Comprehending the thickness markings on polycarbonate sheets guarantees that the materials you select are appropriate for the planned use, be it industrial skylights, residential roofing, or greenhouse construction.

Polycarbonate sheets that are labeled with UV protection can withstand prolonged exposure to sunlight without yellowing, discoloring, or losing their mechanical properties. For outdoor applications, where extended UV exposure may compromise the lifespan and visual appeal of the roofing material, this information is essential.

Polycarbonate sheets with fire rating labels show their safety standards compliance and flammability characteristics. In order to ensure safety and comply with building code requirements, different applications might need different fire ratings. Verify that the polycarbonate sheets fulfill the required safety requirements for your project by looking at the fire rating label.
