Knowing the subtle differences between each type of roofing material can have a big impact on both functionality and appearance. Schifer is one such material that frequently sticks out because of its unusual wave-like profile, which gives roofs a certain charm. The characteristic height of these waves, which are vital in defining a roof’s overall appearance and functionality, is referred to as "schifer wave height."
Schifer, sometimes referred to as slate, is a naturally occurring stone that has been used for roofing for centuries because of its enduring quality. The difference in elevation between the peaks and troughs of the stone tiles is known as the schifer wave height. This variation affects the roof’s practical features, like wind resistance and water drainage, in addition to its aesthetic appeal.
Schifer tiles are usually cut to precise measurements, including wave height, for consistency and simplicity of installation. The type of schifer and the manufacturer’s specifications can affect the wave height. Generally speaking, a smoother, more understated appearance can be achieved with a lower wave height on the roof, while a higher wave height may produce a more pronounced textured appearance.
Schifer’s natural color variations, which range from deep grays to earthy greens and purples, and its aesthetic versatility make it a popular choice among architects and homeowners. When renovating a building, the wave height of the Schifer tiles can make all the difference in obtaining the right architectural style or preserving historical authenticity.

Asbestos -cement slate: nominal and useful sizes
Even with the abundance of different roofing options, Russian developers continue to be interested in slate. This is because slate sheets have a price advantage in addition to their technical qualities. The material’s roofing slate dimensions vary in terms of sheet thickness, width, and length.
The computation of the quantity of materials on the slopes, accounting for overlap and cornation descent, is one of the preparatory steps before beginning the installation of slate on the rafter system.
Self: sizes of wavy sheets
Asbestos-cement sheets come in two varieties: wavy and flat. For roofing, flat sheets are not appropriate. Basically, walls and partitions are constructed with this material. Roofs with a minimum slope of 12 ° are covered in wavy sheets.
Slate is one of the most versatile roofing materials available. Its dimensions allow you to choose the best possible length and width for the slopes of the sheets, and by cutting the slate, you can achieve low-waste roofing.
The production of wavy slate follows GOST 30340-95. Since you can develop individual TU for production, not all factories follow it. In this instance, the variations in slate size are discernible.
The width, length, and thickness of the leaf, as well as the height and separation between waves, define the parameters of the wavy slate. Five, six, seven, and eight mile slates are identified based on the total number of waves on the surface.
Two slate brands are governed by Russian GOST:
- Grassu brand 40/150 with a wave height of 40 mm; wave step 150 mm;
- Cipher brand 54/200 with a wave height of 54 mm; Wave step 200 mm.
Slate of wave dimensions in roofing products vary based on the type of profile.
Types of profiles with wavy slate rectangular shapes are categorized as follows:
- Unified profile. Standard sheet width – 1125 mm, sheet length – 1750 mm. Allows minimizing waste due to large types of sizes compared to other types of sizes.
- Ordinary profile (° C). Standard sheet width – 680 mm, sheet length – 1120 mm.
- Reinforced profile (WU). Standard sheet width – 1000 mm, sheet length up to 2800 mm.
The most common application for unified profile sheets is in residential construction. Because of its 8 mm thickness, enhanced profile is advised for use in industrial construction.
Dimensions of the 7th and 8th wave slate
The most common application for slate sheets, which have seven or eight waves, is roofing for one- to two-story homes and cottages. Cover the outbuildings, such as the baths, with slate. Slate is still used for fences, just less frequently.
The weight of the material, as well as the load indicated by various sheets on the rafter system and the bearing walls, all affect how big a slate sheet should be.
During installation, the slate’s width is one or two waves wide. Developers are drawn to the seven and eight-wave slate because it differs slightly from other sheets in terms of nominal and useful areas.
The dimensions of slate sheets
Slate’s extreme wave is lower in height and has a smaller radius. For overlap to occur, a reduction in parameters is required in order to overlap with the subsequent sheet.
Crucial! The weight and size of the slate indicate that at least three persons must participate in the roofing process, and extra reinforcement should be added to the rafter system before installing the slate.
Wave size 8 slate
One 8 wave leaf has a useful area of 1.57 kV.m, subject to a 16 cm overlap. The sheet’s nominal area is 1.978 square meters. The standard sheet weighs 26.1 kg.
Typical slate wave, size 8:
- sheet width 1130 mm;
- sheet length 1750 mm;
- Leaf thickness 5.8 mm.
Wave size 7 slate
Seven wave sheets have a nominal area of 1.715 square meters. The area of the useful sheet is 1.336 square meters. Weight of a standard sheet is 23.2 kg.
The wave’s standard slate size is seven.
- sheet width980 mm;
- sheet length 1750 mm;
- Leaf thickness 5.8 mm.
GOST 30340-95 governs the height and step of the waves in the seventh and eighth wave slates.
- wave height – 40 mm;
- wave step – 150 mm;
- sheet thickness – 5.2 or 5.8 mm.
Crucial! The extreme waves of the sheets—covered on one side and covers on the other—are taken into consideration when calculating the slate roof. The overlap maintains the integrity of the roof structure and waterproofs the roof.
Additional types of slate sheets
Used less frequently in the configuration of 5 and 6 wave slate private roofs. The majority of them are covered by storage and production buildings.
Eight wave sheets are the same size as the geometric dimensions of five wave slate. Because there is a significant discrepancy between the nominal and useful areas of the 5-wave slate due to its reduced wave count, adhering to the required overlap results in a material surplus.
Six wave sheet dimensions:
- width – 1125 mm;
- length – 1750 mm;
- sheet thickness – from 0.6 to 0.75 mm;
- Wave step – 200 mm.
7.5 mm thick shifter sheets can sustain a significant load when bent and are resistant to mechanical damage. Compared to equivalent slates with a thinner sheet, this slate has twice the impact and frost resistance.
The following benefits of slate account for its popularity:
- inexpensive cost;
- long service life;
- moisture resistance;
- non -combustibility;
- low thermal conductivity;
- Frost resistance.
Another benefit of the material piggy bank is that you can make the asbestos-cement sheet roof by hand. Additionally, because the slate has been stained by the factory, these products are no longer plain and gray.
In the realm of private construction, slate sheets remain relevant. Prior to purchasing, it’s crucial to ensure that the roof can be made without incurring extra costs.
The dimensions of the sheet 6, 7 and 8 of the wave slate (weight per 1 m2, useful area, length, width, thickness)
The most widely used roofing material that has been around for a few decades is slate.
Real slate is a naturally occurring layered mineral, hence the term "slate" is not totally accurate.
The roofing material’s official name sounds like an asbestos-cement sheet, but "slate" is a well-established term that makes no sense to change.
There are two primary kinds of material: wave and flat. Flats are utilized for facing projects or to construct home and auxiliary space partitions.
Because a roof coating is only applied in waves, the waves produced by the stiffness create a material that is stronger than flat.
Slate is a material that is widely used because it is very dependable, long-lasting, and simple to install. The market’s recent introduction of numerous alternative roofing coatings composed of metal, bitumen, or synthetic materials could not significantly alter the situation because builders still primarily use tried-and-true, conventional methods when choosing materials.
Technical characteristics of the wave slate
Wave slate is a type of roofing material that is shaped like wavy rectangular sheets. Slate is produced using a plastic molding composition that consists of the following components:
- Portland cement. M300-500 brands are used, as a percentage of the material the material is 80-90%.
- Chrysotil-Assbest. (10-20%).
- Water.
Traditionally, the material was produced with a light gray natural color. However, coating samples made with dye additions have recently been available on the market to give the material a specific color, greatly enhancing its aesthetic appeal.
Slate nails are used to mount overlapping sheets to the rafter system during installation. Skates and docking elements are also manufactured by industry; however, builders frequently use metal elements without knowing this, which detracts from the aesthetics of the roof.
Slate of the wave dimensions of the sheet (7 and 8 waves)
As per GOST, there exist solely two categories of size:
Depending on the type, slate 8 mi waves also come in different sizes. Sheets are separated by profile type:
Tagged with the uv acronym.
Wave size of slate 8:
- Sheet width – 1130 mm;
- Length – 1750 mm;
- Leaf thickness-5.8 mm for profile 40/150 and 6-7.5 mm for profile 54/200.
The wave’s slate 7’s dimensions:
- Sheet width – 980 mm;
- Length – 1750 mm;
- Leaf thickness-5.8 mm for profile 40/150 and 6-7.5 mm for profile 54/200.
The slate 6 is wave-sized.
- Sheet width – 1125 mm;
- Length – 1750 mm;
- Leaf thickness-5.8 mm for profile 40/150 and 6-7.5 mm for profile 54/200.
The wave’s magnitude and slope
- Sheets 680 mm wide;
- length – 1120 mm;
- The thickness of the sheet is 5.8 mm for the profile 40/150 and 6-7.5 for profile 54/200.
There is a tiny range of variation in the wave’s slope 8.
The marking profile, specifically made for industrial settings, has a thickness of 8 mm, a sheet width of 1000 mm, and a length of up to 2800 mm.
The maximum allowable dimensions are +10 and -5 mm for width and ± 15 mm for length.
The number of waves
The terms "seven-wave" and "eight-wave" already indicate how many waves there are.
A 7-wave sheet is most frequently used in individual construction because it is simpler to handle and easier to lift to the installation location.
Since the overlap in both brands is the same and there is nothing to make up for the difference in one wave, its useful area is less than that of the 8-wave.
Nonetheless, the demand analysis reveals that a 7-wave option is most frequently used.
How much slate roof weighs
An essential metric that determines the load on the rafter system is sheet weight. Now, let’s determine the weight of the slate leaf of slate 8 using the wave and 7 wave.
The profile sheet has a weight of 40/150.
The weights for the 54/200 profile are 26 and 35 kg, respectively.
About 10.41 kg is the weight of the slate 8 wave 1 m2.
Compared to other roofing materials, slate is known to weigh more, which means that the rafter system’s device needs to meet specific requirements. Consideration should also be given to the wind load. The water that is absorbed by the coating during rainy seasons can have a significant impact on a large portion of the roof.
The wavy slate’s weight
Effective area
One sheet installation is overlapped, and two waves are installed less frequently. Concurrently, the sheet’s useful area reduces by the overlap’s size.
- For a 7-wave sheet, the useful area is 1.336 sq. m.;
- The useful area of the slate 8 of the wave – 1.57 sq.m.
The sizes are shown with a single wave overlap, which is most frequently used in construction. Оногда именно возникнуть соблазных положить лист встык, для экономии материала.
One or two sheets saved will allow water to enter the space.
Advantages and disadvantages of slate coating
There are several indisputable benefits to the wave slate:
- Long service life. On average, the coating retains its qualities for about 40 or more years, depending on the conditions of use. It is noted that even with a combination of the most unfavorable factors, the coating serves at least 10 years.
- Simplicity of installation. Work does not require high qualifications, it is enough to have a general idea of styling techniques.
- Allows partial repairs or the replacement of individual sheets that became unusable.
- The strength of the material contributes to the safety of installation – the slate coating freely withstands a person’s weight, allows you to walk on coating.
- Does not accumulate an electric charge, Absolutely safe in fire.
- Much cheaper other roofing materials.
- Relatively small weight Coating allows you to do without construction lifting equipment when installing.
Negative traits about Shifer are unavoidable. Among them are:
- The fragility of the material. Slate is not plastic, does not allow any deformation.
- Moisture absorption ability reduces the service life and causes the formation of fungus, mold, over time, moss appears, which must be cleaned. This drawback can be neutralized by staining.
- The content of asbestos as a component of the material is a significant threat to health.
Despite the lack of precise medical data on the matter, this is the primary cause of slate’s removal from the market. There is statistical data on the percentage of incidence among employees in businesses, but not on the people who live in homes coated in slate.
However, danger must be acknowledged as it exists. Respiratory protection equipment should be used individually when performing installation work.
The material’s drawbacks are easily countered; all you need to do is be aware of them and take appropriate action to avert potential mishaps. However, slate makes a strong case for itself as a cost-effective and dependable roofing material thanks to its clear benefits, which have been demonstrated and validated over many years of use.
The wave slate’s dimensions are as follows: length, width, thickness, and useful area; wave counts are 6, 7, and 8. The sheet weighs one meter.
This article will tell you how big the slate is, including its length, width, and lengths of waves 6, 7, and 8, as well as its thickness and useful area of one square meter. It will also tell you how much the slate wavy coating weighs and discuss the benefits and drawbacks of the roof.
Wave slate: an overview of technical characteristics + its comparison with other coatings
A decade ago, the wave asbestos -cement slate was the most popular roofing. Later his positions in the market were shaken. Modern analogues of this material appeared – made of metal, bitumen and even plastic. However, despite this, many consumers when coating the roof prefer not popular ondulin, but the usual wave slate. This is explained by the fact that most modern materials have not yet passed the test of time, they poured into our markets only 10-15 years ago. A completely different matter – wave slate. It is known that for him and 50 years of operation in our conditions is far from the limit. In addition to durability, slate has a lot of other advantages: low price, practicality, and ease of installation.
Wave slates are rectangular sheets made of asbestos cement with a wave-shaped profile. To make them, a plastic solution made up of the following is formed:
Chrysotil-Axbest serves as a reinforcing aggregate and cement as a binder in the Portland slate. Chrysotil-Assbest gives the material a strong structure by holding a delicate cement mortar in a predetermined wavy form.
The characteristics of the wave slate
Examine the wave slate’s key technical features, which enable it to be used everywhere and on a variety of building types.
Slate is made in accordance with GOST 30340-95. This document states that sheets with 6.7 or 8 waves should be found in asbestos-cement wavy sheets.
The most useful sheets are those with waves seven and eight. This is because their nominal and useful areas differ slightly. The nominal total area of an eight-wave slate is 1.978 m^2, while its useful area is 1.57 m^2. That is, a small portion of the material is lost when installing such a slate on overlaps (1-2 waves on both sides). Regarding the seven-wave slate, the same can be said. Its useful area is 1.3362 and its nominal area is 1.715 m 2.
When installing the roof, there will be a slight increase in the consumption of the six-wave slate. The standard sheet with six waves has a total area of 1.97 m³. In addition, 1.41 m 2 is a useful area. Overlaps thus occupy around 20 percent of the total material.
Some factories produce material with 5 waves in addition to slate with the 6th, 7th, and 8th waves. It should be noted, nevertheless, that this type of material is made in accordance with the factory’s specifications rather than the GOST standards.
Wave lengths of profiles
The height and pitch of the wave determine the type of slate profile. Sheets with two different section types—40/150 and 54/200—are released, per GOST. Simultaneously, the wave height is indicated by the first figure in the fraction (numerator), and its step (in millimeters) is indicated by the second figure (denominator).
The wave height is the distance between the highest and lowest point of the slate of the slate. In a fraction denoting the type of cross section, an ordinary wave height (40 mm and 54 mm) is indicated. There are also extreme waves. On one side of the sheet, the wave is called overlapping, and on the other – overlapping. The height of the overlapping and private waves is the same. The height of the overlapped wave is slightly less. For slate sheets with a section of 40/150, an ordinary and overlapping waves – 40 mm, the height of the overlapped wave is 32 mm. Section 54/200 implies the following height values: for ordinary and overlapping waves – 54 mm, for an overlapped wave – 45 mm.
A wave step, represented by the second fraction figure (150 and 200 mm), shows the separation between the vertices of two adjacent waves.
The size and profile size of the slate directly affect its thickness. 5.8 mm thick sheets with a 40/150 profile are produced. Increased thickness is necessary due to the larger cross section; otherwise, the material will not be able to support its own weight and will disperse during installation or the first few hours of operation. As a result, the thickness of sheets with profile 54/200 is either 6 mm or 7.5 mm.
The current GOST regulates the wave slate’s dimensions as follows: length: 1750 mm; width: 1125 mm (slate with 6 waves); length: 980 mm (slate with 7 waves); and width: 1130 mm (slate with 8- um waves).
Many manufacturers also produce slate in non-standard sizes at the same time. To ensure that the quantity of material ordered is accurate, it is best to clarify this point at the time of ordering.
The weight of a separate sheet is important to consider when purchasing because the slate must be installed manually. This parameter is dependent on the material thickness, wave count, and profile magnitude.
The weight of typical slate sheets (produced in accordance with GOST):
- Type 40/150, 7 waves (dimensions 1750x1130x5.8 mm) – 23.2 kg;
- Type 40/150, 8 waves (dimensions 1750x1130x5.8 mm) – 26.1 kg;
- Type 54/200, 8 waves (dimensions 1750x1130x6 mm) – 26 kg;
- Type 54/200, 8 waves (dimensions 1750x1130x7.5 mm) – 35 kg.
Slate is typically white-gray in color. However, the slate’s color palette has greatly increased as a result of the application of staining agents. Red, green, blue, brown, yellow, brick, and other colored sheets are produced by factories.
There are two approaches to perform shifter staining:
- Coloring pigments are introduced into the composition of the liquid asbestos mass at the stages of slate production. The color is as resistant as possible, as it permeates the entire thickness of the material. However, the staining of slate in the mass is performed only according to the manufacturer’s own TU and does not meet the requirements of the current GOST.
- Pigmented compositions (acrylic, alkyd and polymer paints) are stained with ready -made sheets of slate. Similar decoration is practiced by factories producing colored slate in GOST. Also, paints can be used for your own coating of slate – to improve its decorative qualities, update the appearance and extend the service life.
Regardless of the staining technique, the slate’s color decoration increases its resistance to frost, lowers its absorption of water, and shields it from damage. In comparison to the gray analogue, the colored slate has an average 1.5 times higher durability.
We can use slate on the roofs of residential and commercial buildings in challenging conditions because of its mechanical and physical characteristics.
The primary attributes are:
- A concentrated stamp load – at least 150 kgf (for 40/150 – with any thickness and 54/200 – for a thickness of 6 mm) or at least 200 kgf (type 54/200, thickness 7.7 mm). In other words, slate freely withstands the weight of objects of 150 or 200 kg. On the slate roof you can freely move during installation, at the stage of operation and repair. Significant snow loads are also not afraid of her.
- Density – observed at a level of at least 1.6 g/cm3 – for the type of 40/150; at least 1.65 g/cm3 – for the type 54/200 6 mm thick; at least 1.7 g/cm3 – for type 54/200 7.5 mm thick. The higher the density indicators, the greater the strength of the slate and its weight.
- The limit of the strength of the bend – 16 MPa – for the type of 40/150; 16.5 MPa – for the type 54/200 6 mm thick; 19 MPa – for type 54/200 7.5 mm thick.
- Residual strength – persists at 90%. This is the level of strength of the destroyed slate.
- Water resistance – 24 hours.
- Frost resistance – 25 cycles – for a shifer type 54/200 6 mm thick and type 40/150, 50 cycles – for shifer type 54/200 7.5 mm thick. These numbers indicate the number of freezing and thawing cycles, which do not lead to visible slate destruction.
Take a closer look at the image below:
Advantages and disadvantages of the wave slate
We will compile all of the wave slate’s benefits into a single list to help you better understand its characteristics. The following are some advantages of this material:
- Durability -On average, the operation of slate roof lasts 30-50 years. Staining further increases this period.
- Fire resistance – slate does not burn, does not spread the flame, so according to GOST 30244 it is characterized as non -combustible material.
- Resistance to atmospheric influences. The slate does not rot, does not deteriorate under the influence of precipitation, withstands significant wind loads.
- Low thermal conductivity. The slate preserves heat in the room well in the cold season, so when arranging a roof, you can save on some part of the insulation layers. At the same time, in the summer, slate, on the contrary, isolates the room from intensive solar radiation. It heats up little, in contrast, for example, from a metal tile or corrugated board.
- Sound -absorbing properties. Asbestos -cement sheets tend to absorb sounds, so the noise of the falling rain or hail will not be heard in the house with a slate roof.
- Decorative. The choice of color wave slate allows you to get a roof with high decorative properties. However, the gray traditional slate also fits well with the architecture of modern cities and villages.
- Simple installation. A roofer covering the roof with a slate does not have to have high qualifications. The scheme and technology of laying wavy sheets are very simple and does not require specialized skills and tools. You can cut slate with almost any cutting tool used in everyday life. For example, a hacksaw, a grinder, a disc saw.
- The use of a sparse crate. Slate – solid material, not bending and not changing shape. Therefore, the roofing crate can be mounted with a fairly large step, optimally – 0.75 m.
- Small cost. The cost of erecting a roof from slate, as a rule, is 2-3 times lower than from other materials. The low price of slate sheets, together with the low cost of their installation, allows you to get high -quality roofs without significant damage to the family budget.
Naturally, despite all of his advantages, slate is not a flawless material and has drawbacks. The following are the main drawbacks of asbestos-cement sheets:
- Fragility. Slate is not able to withstand serious shock loads. For example, a large hail or stone that fell on the roof can leave holes on it. Shipye also does not bear bending efforts, with a minimal attempt to bend, he cracks. This can happen, for example, when the slate is laid on unevenly exhibited rafters or when non -cutting was used for the crate.
- Light weight. A square meter of slate can weigh up to 15-20 kg. This mass of the roof requires the installation of a carefully verified rafter system that withstands significant loads.
- Growing on the surface of mosses and lichens. This is because slate is porous material, into which plant parasites are very easily populated. In addition to deterioration of the decorative type of slate, mosses and lichens relax its fibers, lead to accelerated formation of cracks and the destruction of the material. For the prevention of this process, slate is treated with water -repellent impregnations or paints.
- The content of asbestos. There is an opinion that asbestos -cement sheets, due to the content of asbestos, are non -ecological and dangerous for health. There is another point of view, according to which the dangerous properties of the slate are exaggerated and negative effects are possible only from asbestos fiber (dust) not related to cement mass. If the sheets periodically cover with olifa or paint, then the appearance of asbestos dust in the air is almost impossible. In any case, the slate in our country is not prohibited and the statement about its dangerous action is debatable.
Thus, with appropriate use and extra care, some of the slate’s drawbacks can be mitigated. Some flaws are ludicrous, while others don’t really affect how well the roof functions in the long run.
Considering the material’s undeniable benefits against a few minor drawbacks, we can come to the following conclusion: despite the emergence of more contemporary alternatives, slate roofing remains competitive and promising, with a wide range of applications.
A thorough rundown of the tried-and-true wave slate roofing material. Technical analysis and comparison of slate with alternative coating types for
"Knowing the height of Schifer waves is essential for roofing professionals. This measurement establishes the minimum thickness of roofing material needed to efficiently withstand weather conditions. It has an immediate effect on how well-performing and long-lasting roofs are against weather, wind, and other factors. Roofers can choose durable materials and installation techniques and ensure long-lasting roofs by understanding Schifer wave height."
Weight and size 8 wave slate
One of the most widely used roofing materials a few years ago was asbestos-cement coating. It was widely used in private construction as well as on the roofs of industrial buildings. Although it is easily installed and readily available, the weight of the slate is not the lightest, which requires many builders to use more precise calculations when designing roofs. Such a roof, when styled properly, will withstand atmospheric phenomena and cold for over 50 years, shielding the house and other structures from harm.
The main parameters of asbestos -cement slate
Slate comes in two primary varieties:
The flat option is primarily used for wall cladding and the installation of different partitions in the construction of the economical type; it is rarely used as roofing material. Such materials are manufactured with the aid of specialized technology. Its foundation is a thin chrysolite fiber asbest, which makes up up to 10% of the substance’s overall mass. He is the source of the material’s strength and stiffness, which define its flat form.
Two varieties of flat slate exist, based on the technology used in production:
They differ greatly in their traits. Plot slate needs to be shielded from the elements once it is installed, so different paints are used to coat the sheets.
Sheets of asbestos-cement with a wavy profile are called wave slate. Depending on how many waves there are, it could be:
The GOST has set specific sizes for each option. The primary traits of every species consist of:
- Wave parameters;
- Sheet thickness;
- The width and length of the sheet;
- Schifer weight;
- Color;
- Physical and chemical properties.
All of the aforementioned species are produced using a plastic solution made of Portland cement, asbestos-containing chrysotile, and water. It has durability, firmness, and strength from the combination of these elements. In the video, the production process is demonstrated:
The most popular among consumers and widely used in construction are sheets featuring the seventh and eighth waves. The roof is the primary use for them.
Canvases with five waves are made in accordance with that specific factory, not GOST, unlike those with six, seven, and eight waves.
The size and value of the profile determine this parameter. The transverse section determines the variation, which ranges from 5.8 to 7.5 mm.
The sheet’s length and width
The range of widths for a given profile type is 980 to 1130 mm. Regardless of the quantity of waves, all types have a length of 1750 mm.
This parameter’s value varies depending on the species and is directly influenced by the number of bends, dimensions, and thicknesses. This number is crucial to consider when selecting the roof’s material because it will have an impact on the entire structure, placing weight on the walls and foundation.
Slates with wave dimensions that meet GOST standards can typically be produced in a variety of colors. Although light is the most common color, you can paint sheets in other colors thanks to modern technology.
- The ability to withstand quite large weight loads – up to 200 kg, which allows you to freely move along the roof during installation, and also not be afraid of the load provided by snow;
- High density that provides strength;
- Water resistance up to 24 hours, and when processing with special compounds and longer;
- Frost resistance.
Numerous benefits come with this material, including its high resistance to atmospheric phenomena and durability. has a low heat conductivity, is easy to install, and absorbs noise and fire. It is affordable due to its low cost and suitability for a sparse crate.
While it is not without its share of weight, it is also quite substantial, so this should be considered when selecting it for roofing. Slate is very prone to damage from shock loads, and high humidity can cause mosses and lichens to grow on its surface.
Parameters depending on the number of waves
The slope 6 wave is typically 1750 mm by 1125 mm in size. It is manufactured in compliance with GOST and needs to meet the following technical requirements:
- With a wave step 20 cm;
- Rib height 5.4 cm;
- The thickness of the leaf within 0.6 – 0.75 cm;
- The width of the canvas – 1125 mm;
- Length – 1750 mm.
In addition to having fewer ribs than the previous profile, Speaker 7’s wave parameters have additional differences.
Its width is only 980 mm, while its length is likewise 1750 mm. Additionally, it is 0.58 centimeters thick.
Every wave is leveled off from the 150 mm-sized step before it. The GOST states that it should be 40 mm tall.
Like all other species, the slate of an 8 wave has a width of 1750 mm, but it is significantly wider than that of a sheet with seven waves, which is 1130 mm. Similar to Semillevov, the height and step of the wave for such a material are 40 and 150 mm, respectively.
For convenience, the parameters of all kinds that aid in more precisely estimating the weight and dimensions of the slate are condensed into a table.
Because of their parameters and qualities, the eight-wave and seven-wave types are the most sought-after in the construction industry, particularly for use as roofing materials. When covered in such a material, the roof will endure a long time and provide dependable protection from winds, precipitation, and the cold.
One of the most widely used roofing materials a few years ago was asbestos-cement coating.
Wave Height | Definition |
Schifer Wave Height | The height of waves measured from the trough to the crest, specifically in the context of roofing, indicating the maximum vertical distance. |
Anyone working in roofing needs to know how high a Schifer wave can get. This measurement indicates how well water and debris can flow off the roof by measuring the distance between the wave’s base and peak. Higher wave heights result in more effective drainage, which lowers the possibility of damage and water pooling.
The height of Schifer waves is significantly influenced by roofing materials. Higher waves are typically formed by materials with more rigidity, which can improve drainage but may need careful installation to avoid possible problems. On the other hand, flexible materials with lower wave heights, like EPDM, might need different drainage and maintenance strategies.
Schifer wave height is also influenced by climate and roof pitch. Naturally, steeper pitches promote faster water runoff, which has an impact on wave formation. Wave height becomes essential in areas that frequently experience high levels of rain or snow to prevent water buildup, which over time may cause leaks or structural damage.
In the end, any roofing system’s longevity and efficacy depend on its ability to comprehend and control Schifer wave height. Homeowners and contractors can guarantee ideal drainage and protection against weather-related wear and tear by selecting materials and designs that are in line with regional climate conditions and installation best practices.
