The weight of one sheet of Ondulin

It is important to consider the weight of roofing materials when making installation and structural integrity decisions. In contrast to more conventional roofing materials like tiles or shingles, ondulin is lightweight and a popular option for roofing because of its affordability and durability. Because each sheet of Ondulin weighs roughly X kilograms, it is easier to handle during installation and places less strain on the structural integrity of the roof.

Ondulin is lightweight, but it doesn’t compromise strength or resistance to the elements. Made of cellulose fibers impregnated with bitumen, it provides outstanding wind, rain, and UV protection. Its composition not only adds to its longevity but also guarantees that it can weather the elements without gradually losing structural integrity.

Because Ondulin sheets are lightweight, installing them is simple. This feature makes roofing easier, which lowers labor costs and makes it more do-it-yourself friendly for enthusiasts. The sheets are made to tightly interlock, improving the roof’s resistance to water infiltration—a common issue with roofing materials—by creating a tight seal.

The weight of each material must be taken into account when organizing a roofing project to make sure the structure can support it. Compared to heavier alternatives, Ondulin’s lightweight design not only makes installation simpler but also places less stress on the building’s framework. Because of this feature, it is a sensible option for a range of roofing applications, including both residential and commercial structures.

Features of Ondulin – a useful size of a leaf, overlap and width, technical characteristics

Euro-shifer, also known as ondulin, is a highly dependable roofing material. It will be necessary to know the standard size of ondulin during the calculation measures in order to prevent shortages or surpluses during roof laying.

Features of the manufacture of ondulin

The name "Onulin" comes from the French company that holds the patent for this product, Onuline. This material differs favorably from traditional asbestos cement slate in that it is made entirely of safe and environmentally friendly components.

Pure cellulose is utilized in the manufacturing process, and etheric resins and bitumen are used to impregnate it. The Italian-French version of "Ondwill" first surfaced not too long ago. This new material is designed to look like ceramic tiles and has a composition similar to ondulin.

The following procedures are employed in the ondulin production process:

  1. Cleaning cellulose. Garbage and impurities are removed from its composition. Then the substance is soaked in water, with pigments diluted in it and modifiers. The resulting raw materials are called "pulp".
  2. Pulp processing. This happens on a special conveyor, where the material is pressed to a thickness of 3 mm. Having dried up and hardened, the pulp acquires specific waves.
  3. Bituman impregnation. Pulp base with an area of ​​1.9 m2 is impregnated using oil bitumen.
  4. Stuffing of finished material. The packaging is used as a heat -shrink film equipped with a label and accompanying information.

Sheet size, taking into account the overlap – useful width

The fact that Ondulin is consistently made in standard sizes is incredibly convenient. If variations in the width or length of wavy sheets are observed, we can infer that forging interrogative quality is most likely the subject of discussion. Once the useful size of the Ondulin sheet is known, determining the total coating quantity is a simple process.

The Ondulin sheet’s standard size is:

  • Ondulin"s working width – 950 mm. Very convenient size to arrange a roof of small and medium area.
  • Length – 2000 mm. Round number makes the calculation of the material very simple.
  • Thickness – 3 mm. Small deviations are allowed in this parameter.
  • Profile wave height – 36 mm.
  • The weight of one sheet is 6 kg. One square meter – 4 kg.
  • Liszt Square – 1.9 m2.
  • Useful area of ​​Ondulin Smart – 1.6 m2. At the same time, vertical and horizontal overlaps are taken into account.

Armed with information about the total area of ​​roofing slopes, to calculate the number of ondulin sheets, no significant efforts will be required. All that is needed is to divide the area of ​​the roof into an indicator of the useful area of ​​one sheet (1.6). For compensation for circumcision, 15% is added to the amount received. Also, one should not forget about adjusting the size of the ondulin sheet, taking into account the overlap: this is affected by the angle of slope of the slopes. In this case, the beneficial width of Ondulin will differ from the working. When calculating the useful width of the Ondulin sheet from the standard indicator, the size of the side overlap is taken away.

The strengths of Ondulin

When ondulin sheets were first introduced, their use was limited to quickly patching and caulking leaks on metal, slate, and tile roofs. The practice of applying the Euro-shifer revealed that it is a very suitable roofing material on its own.

This was made possible by the qualities listed below:

  1. Small weight. Without exaggeration, we can say that Ondulin is the easiest material for the roof. This allows you to lay it directly on the old slate or profiled sheet without dismantling.
  2. The duration of the service. Ondulin roofing can be painlessly transferred to 100 frost and defrosting, which allows the manufacturer to give a warranty for 25 years. As practice shows, Euro -shifer has been serving at least 50 years.
  3. Good strength. The presence of a wavy profile allows the material to have a bearing capacity of 650 kg/m2. He is not afraid of snow loads up to 300 kg/m2.
  4. Hydrophobic. Ondulin does not pass and almost does not absorb water, which allows guaranteeing reliable protection of the rafter structure from getting wet.
  5. Soundproofing. The surface of the Euro -shifter has noise -absorbing characteristics. On such a roof is almost inauded to rain, hail or strong wind.

When selecting ondulin for roofing, it’s critical to consider that this material is combustible. The sheets will start to distort if you operate above the manufacturer’s recommended temperature range of + 110 degrees. This means that baths, arbors with barbecues, homes with fireplaces, and solid fuel stoves shouldn’t use Euro-Shifer.

How to cut ondulin and its characteristics: the size of the leaf, thickness, useful area and weight of one sheet

An essential step in lowering a home’s heat loss is installing insulation on the roof.

The roof should shield the structure from the elements and wind.

There are numerous materials available, but a few stand out as being the most popular.

Ondulin, a material with French origins, is one of them.

Russia has already begun producing this material.

Ondulin, and what are its advantages and disadvantages

Ondulin is made of bitumen-saturated cellulose mixed with minerals and resins.

Ondulin is perfect for residential structures. Because it’s so inexpensive.

When laying a roof, the same question always comes up: "How to cover the roof beautifully, high quality, and inexpensively?"Among the materials claiming to simultaneously meet all three requirements, Ondulin earned a rightful place.

This substance is occasionally referred to as an Euro-shifer. He’s attractive, warm, and reasonably priced. What is he in reality?

We will first go through the benefits and drawbacks of ondulin before discussing how much of it is consumed when it is laid on the roof and problems with its working area.

  • High -quality insulation from water,waterproofing. A characteristic arrangement of the fibers of the material, characteristic only of ondulin, as well as bitumen impregnation – all this guarantees the absence of water, riding this material from its ingestion. If she got there, then when freezing, the roof was deformed.
  • Price quality. The use of simple materials, but at the same time possessing a gamut of useful properties, immediately brought this material to the market leaders in this indicator. Its quality is much higher than its price.
  • Withstands large temperature changes. The range of operation, in which the use of ondulin is allowed – from minus 40 degrees of frost to 80 degrees of heat.
  • Strength. Ondulin is stressful – it withstands a hurricane wind, gusts of squall wind can reach 70 meters per second (this is 200 km per hour), the pressure of the mass of snow. Strength – 300 kilograms per 1 sq.m. Abundant summer rains also does not pose a danger to him.
  • Noise insulation. The nature of the interweaving of Ondulin fibers provides him with excellent soundproofing.
  • Simplicity of use. The flexibility of the material gives him unsurpassed possibilities for laying. Easy to bend and lay in the right place.
  • Durability. The service life is up to 50 years, and the warranty on water resistance is 15 years.
  • Environmental friendliness. Safe for you and the environment due to the use of natural, natural components.
  • Chemical stability. Resistant to acids, alkalis, oils, fungi. This is important, for example, in areas with the presence of chemical industry enterprises that emit a drop of chemicals into the atmosphere.
  • Ease. How much ondulin weighs? One sheet weighs about 6 kg.
  • Designing is successful because it is presented in a wide range.
  • Flexible, can be transported by folding it in half or twisting.
  • The material is absolutely fireproof, but at the same time, Not a fire. When heated to 250-300 degrees, it is spontaneous.
  • It is for this reason that with the roof of kindergartens, hospitals, social facilities and institutions, it is laid by sections so that in the event of a fire situation, fire would not be thrown into neighboring sections of the roof.
  • It can also change the color from the effects of sunlight and It has a tendency to fade. It can also fade it, depending on the fall of the sun, where there is more, where it is smaller, turning into a variegated canvas.
  • Bitumen spots can appear on the surface of the sheet. This is considered the norm and is not a marriage.

Ondulin the size of the sheet

The leaf ondulin sizes for the roof are constant and have predetermined values (the ondulin’s working size):

2000 mm in length

The working width of Ondulin is 950 mm.

Naturally, there are tolerances or errors stated by the manufacturer, i.e., the difference between the nominal and actual sizes, just like in any technical business.

These tolerances for ondulin are as follows:

  • In length – 2 meters tolerance – more by 10 mm or less by 3 mm
  • Width – 95 cm plus minus half a centimeter.
  • In thickness, the deviation is allowed in two tenths of millimeters, 0.2 mm.

Size of Ondulin work sheet

Now that we are aware of the size of Ondulin for the roof, we can determine the leaf’s usable area and the Ondulin wave’s height.

Useful area of Ondulin (the size of the leaf ondulin, taking into account the overlap)

How can the size of the Ondulin for the roof be calculated? The Ondulin sheet has a standard total area of 1.9 square meters. Visible, overwhelming, and moving areas are not counted as useful areas. One wave may overlap another, or there may be two waves.

Furthermore, the variation in the roof slope, also known as the angle of inclination, can affect the sheet of sheets from top to bottom. Everything that is crucial to know about installing ondulin is covered in this article.

Ondulin’s working area is thought to be between 1.3 and 1.6 square meters, with a very steep roof, when using large letters of sheets stacked on top of one another to create two waves.

Despite the masters’ assertion that you won’t make a mistake if you figure out how many sheets there are and divide the roof area value by 1.5.

A dedicated program is available to determine the quantity of sheets. You can use our online calculator or safely download ONDULINEROOF from the Internet.

Actually, all you really need to know is the roof’s area and size. It gets easier if it has a straightforward geometric profile that can be split into distinct rectangles, triangles, or at the very least trapezoids, the area of which is found using well-known formulas.

The area of the roof, which is the sum of the areas of geometric shapes and their components, can be used to calculate the number of sheets of Ondulin by dividing the resultant value by 1.5, 1.3 for a very steep roof, or 1.6 for a gentle roof that is up to 10 °.

How much does Ondulin sheet weigh?

The leaf ondulin weighs 6 kg, give or take 300 grams.

How to cut ondulin

Ondulin frequently needs to be cut during installation, occasionally into tiny pieces in order to lay the material around chimneys and other intricate roof areas. If the overlap appears to be excessive, you frequently need to trim the excess.

Clerical knife on a cutting sheet

Recall that ondulin was cut from the "facade," or the front side, which is what fits into the sky. Moreover, it is sliced by the space between the waves rather than within them.

How is ondulin cut? The following is the cutting method:

  1. An incision is made. That is, cutting begins with the performance of the cut on the front side. Then the sheet is bent, turned over, and it is cut further.
  2. How to saw ondulin? For these purposes, ordinary stationery knife. It allows you to carry out even cutting that does not leave the "covered" edges, everything will be clearly and evenly.
  3. This is if it is implied on the sheet. If across, then there is nothing better than a classic hacksaw for a tree. But there are certain features. Such cutting also goes on the front side. But you need to pre -make high -quality markings in order to cut exactly along the line.
  4. If you need to cut many sheets, you can use the "circular", that is, the circular saw. The circular saw gives an even correct incision.
  5. As for cutting a grinder, you can use it, but carefully. It is necessary to ensure that the edges of the cut are not melted, since when cutting a grinder at high speeds due to friction, the temperature of the material at the cut site from the circle rises.

Ondulin should not be cut in the sun. It is imperative to perform this shadow work in a cool room if possible.

Alternative roofing

A roof made of corrugated board, galvanized iron, roofing material, tiles, and the most significant material available today—metal tiles—could be an alternative to an Ondulin roof.

The roof’s galvanized iron covering is well-maintained and offers long-term protection from rain and moisture.

Because the snow on the roof doesn’t accumulate over time, you can use thinner rafters and save money on a galvanized roof.

  • Classic roofing material – Star among roofing materials. It is easy to transport, it is at all inexpensive, easily fits – it is in advance in demand. Now an improved roofing material has appeared more modern brands, it has become even more popular. Mechanically resistant to influence, durable, has high elasticity – it is not for nothing that they are covered with roofs of residential buildings, at least many houses of Soviet buildings are covered precisely by roofing material.
  • Corrugated board (profile) – high -quality modern material pressed from rolled steel. Very durable, light, easily mounted, resistant to environmental effects and durable.
  • Metal tile – King of the roof. Metal with tiles combines the advantages of both, eliminating their disadvantages. It looks better than just metal, and properties are better than that of the tile. Ensures the simplicity of installation and durability, it is very popular among builders. Why is there a place for other materials, like Ondulin? The question is in price.
  • Tiles It happens from burned clay (ceramic tiles), thermoplastomosite, sand solution with cement (cement-sand) or lime with sand with heat treatment (silicate tiles). The most famous clay tiles are made of plastic clay with a low melting point (sometimes a material such as a shame is added to it). Classic tiles are fragile and heavy. The roof for it should have a steep slope for a slope of water. Modern models can be laid on gentle roofs (10 °).
  • Is there some more slate, but he is seriously not considering. And in Europe, it is prohibited for use due to asbestos. Although we can still cover the sheds. The manufacturer is still important here – now they manage to do unevenly.

Ondulin: sheet dimensions (width and length), useful area, wave height, weight of the sheet, thickness, and working area; how to saw and cut ondulin into pieces

This article will teach you about the dimensions of the Ondulin leaf (length and width), the roof sheet’s useful and working area while accounting for overlap, the wave’s height, and the weight of the Ondulin leaf. We will ascertain the millimeter thickness of the sheet, as well as the proper tools for sawing and cutting an ondulin leaf.

Technical characteristics of Ondulin

In the first part of the 20th century, ondulin made its debut on the construction industry. This material is a more ideal and cozy substitute for slate.

Due to the use of premium materials in his construction, Ondulin has numerous benefits. We will discuss the primary properties of a substance like ondulin.

The dimensions of the Ondulin sheet

The dimensions of ondulin’s width and length are 95*200 cm, and it is produced and sold in sheets with a thickness of about 3 mm. The surface of the sheet is corrugated, and the waves are 36 mm tall.

Because the ondulin sheets are layered over one another during installation, the material’s usable area is only 1.6 m. When conducting settlement work intended to determine the required quantity of material, this fact should be taken into consideration.

Every ondulina leaf produced by pressing pulp fiber and then coating completed sheets with a bitumen mixture. Mineral components and curing resins are applied as the final layer on the ondulin sheets.

Their details:

  • Protective qualities;
  • Duration of life;
  • An attractive appearance.

The majority of onilin sheet manufacturers follow industry standards, and a 2 to 5 mm size error is acceptable. One onion leaf has a surface area of about 1.92 square meters.

The usable area of Ondulin, the number of overlaps, and the ceilings must all be considered when determining how much material is required to coat the roof.

The weight of the leaf ondulin

Ondulin’s low weight is a result of his construction from light materials. It weighs roughly 6 kg per sheet. These Components form the foundation of Ondulin:

  • Cellulose fibers;
  • Purified bitumen;
  • Smolly polymer impregnation;
  • Natural pigments made on the basis of mineral harmless components;
  • Mineral filler.

Thanks to this ready-made, the bitumen and polymer compositions are impregnated under high pressure into the cellulose base of the ondulin sheets. The product’s strength margin is wide.

You can get various shades of ondulin sheets by adding different mineral dyes.

The installation of ondulin is greatly facilitated by its small weight. Additional funds won’t be needed because it is not necessary to purchase more pricey construction equipment in order to lay sheets.

Furthermore, the transportation of Ondulin sheets to the construction site is executed without any issues.

Ondulin service life

Every year, Ondulin roofing materials gain more and more appeal. This is due to a number of factors. This material has great technical qualities and is universal and LEGOK in installation.

Furthermore, Ondulin has an extremely long service life. Long-standing producers of ondulin offer warranties to their clients for a maximum of 15 years on their products. In actuality, Ondulin has a far longer service life.

The Ondulin coating can withstand 20 or even 30 years without needing to be repaired if the sheets were installed correctly and the roof is maintained in compliance with the guidelines.

The length of Ondulin’s service life is attributed to the material’s high stability at varying temperatures. This is particularly crucial during the off-season, when there are frequent and dramatic variations in the outside air temperature.

Ondulin is not affected by strong frosts or intense heat. Such unfavorable conditions prevent the material from melting or cracking.

Ability to support large loads is one of Ondulin’s other key advantages. There is one subtlety here, though. Only if the crate is arranged correctly—this component is in charge of the proper distribution of loads—will the material be able to bear the weight produced, say, by a significant quantity of snow.

In the first part of the 20th century, ondulin made its debut on the construction industry. This material is a more convenient and sophisticated version of slate. Due to the use of premium ingredients, ondulin has numerous benefits. We will discuss the primary attributes of this kind of content as


It’s likely that even people unrelated to construction have heard of Ondulin.

The use of this contemporary roofing material is growing.

We advise you to carefully read the entire publication to get a sense of this contemporary material if you’re unsure about which is better: metal tiles or ondulin.

The production of Ondulin

Ondulin is made in Russia as well as overseas. The natural raw material used to make ondulin is cellulose, which is easily obtainable and safe for the environment. Even though Odulin is sometimes referred to as a "Euro-Shifer," its primary distinction from slate is that it is more environmentally friendly and doesn’t contain any asbestos fibers that could be harmful to people’s health.

Ondulin’s fame was fueled by attributes like these:

  • high strength;
  • elasticity;
  • environmental resistance;
  • small weight;
  • Wide color scheme.

Ondulin essentially doesn’t absorb water because of its low water absorption, which can cause roofing material to freeze and break.

When it rains, the ondulin roof makes less noise than a roof composed of galvanized iron, profiled sheet, or metal tiles because of its excellent absorption of sound.

There is currently a huge variety of color schemes available on Dulin. This allows you to always select the color of Ondulin that will work best to cover the roof of your suburban cottage or bathhouse.

Once the quantity of ondulin sheets required for the roof device has been determined, you must determine the purchase price.

The weight, width, and length of the roofing ondulin sheet, as well as its physical attributes, are its primary characteristics. How much ondulin costs. Where do I purchase?

Ondulin Type Weight of One Sheet (approx.)
Standard Ondulin Sheet Around 6 kilograms

Due to their reputation for being both lightweight and durable, onduline roofing sheets are a well-liked option for roofing solutions. Because Onduline sheets are generally lightweight—roughly 6 kg or 13 pounds—handling and installing them is made easier.

This lightweight feature lowers the load-bearing requirements of the roof structure while also making transportation and installation more manageable. This is especially helpful in areas where structural support is important, like those that are vulnerable to earthquakes or where keeping construction costs as low as possible is necessary.

Onduline sheets are made to withstand a variety of weather conditions well, even though they are lightweight. They are made of bitumen, organic fibers, and resins and are designed to offer strong defense against moisture, UV radiation, and temperature changes. This guarantees durability and dependability in a range of weather conditions, from humid tropical settings to severe winter weather.

In summary, each Onduline sheet’s manageable weight promotes structural integrity and reliable weatherproofing while also improving installation efficiency. All of these qualities combine to make Onduline a great option for roofing applications on homes and businesses, offering durability and practicality.

For every roofing project, the weight of a single sheet of Onduline roofing material is an important factor to take into account. Knowing its weight enables homeowners and builders to assess the installation’s viability and guarantee structural integrity. With an average weight of 6 to 7 kg per square meter, onduline sheets are a lightweight yet strong choice for a range of building applications. This weight factor highlights the usefulness and effectiveness of utilizing Onduline for roofing solutions by influencing transportation costs, handling ease during installation, and the overall load on the roof structure.
