Onduline, also known as Ondulin, is a roofing material that is distinguished by its durability and adaptability. This lightweight roofing option has become well-known all over the world due to its cost-effective advantages and resistance to a range of weather conditions. Constructed from organic fibers saturated with bitumen, Ondulin sheets are renowned for their durability and ability to withstand corrosion, rendering them appropriate for use in both residential and commercial structures.
Ondulin’s usefulness goes beyond providing weather protection. Compared to conventional roofing materials, installation is simpler and takes less time because of its lightweight nature. This is a sensible option for new construction or renovations because it lowers labor costs and the structural load on buildings. Furthermore, because of its adaptability, roof designs can be creatively created to suit a variety of architectural preferences and styles.
Ondulin’s superior thermal and acoustic insulation qualities are among its main benefits. By preventing heat gain in the summer and heat loss in the winter, the material helps control indoor temperature. It also absorbs sound, which lowers building noise levels. This makes Ondulin more than just a roofing material—rather, it improves comfort and energy efficiency, making homes and workplaces more livable.

The size of the Ondulin sheet and its useful area
For more than 50 years, the sheet material created by the French business ONDULINE has been one of the most widely used materials for roofing arrangements. Ondulin is currently produced in a number of nations, including Russia. The color shades of various parties may differ slightly because of the characteristics of the technology used to manufacture the material. To ensure that the roof has a visually appealing appearance, it is advised to use roofing material from a single batch after precisely determining how many sheets are needed.
The characteristics of Ondulin
Ondulin is actively used in the construction of light structures such as pavilions, kiosks, awnings, and arbors, as well as capital facilities such as residential, commercial, and industrial buildings. This leaf material’s light weight makes it perfect for repairing old roofs because it can be installed on top of flat, outdated roof coatings without worrying about placing too much weight on the structure’s foundation. The new flooring will weigh roughly 3 kg per square meter.
The material is made using a very basic technique: cellulose fiber is pressed into wavy sheets that resemble conventional slate. Subsequently, bitumen is injected into the base, and cured resins and mineral pigment are applied to the material’s upper layer. Ondulin’s thin thickness facilitates installation; sheets can be raised to the roof, cut, and styled on curved surfaces with ease because the material bends both longitudinally and transversely. The standard sheet has a total area of 1.9 m 2.
Among the benefits of ondulin are:
- long -term operational period (guarantee – 15 years, real service life – 50 years);
- attractive appearance;
- resistance to moisture and atmospheric influences (fluid wind up to 200 km/h, temperature from -40 to +80 ° C);
- high coefficient of noise absorption;
- simple installation;
- resistance to biological destruction, exposure to acids, alkalis, oils;
- ability to withstand a load up to 300 kg/m 2 .
Unlike a regular slate, ondulin doesn’t include any dangerous ingredients or negatively impact your health.
The dimensions of Ondulin
Ondulin, which is produced in Russia under license from a French company, is typically sold there. The standard sheet measures 2000 mm in length, 950 mm in width, 3 mm in thickness, and 36 mm in wave height. The wave’s length, width, and height may all have errors up to +10/-3 mm, +5/-5 mm, and +2/-2 mm, respectively.
The ten waves that are approximately 95 mm wide on each Ondulin sheet must be considered when determining how much material needs to be used to cover the roof. One wave must overlap one another when installing a horizontal row to guarantee the flooring’s strength and tightness. When laying ondulin on a roof with a slope greater than 15 degrees, there should be a vertical overlap of at least 100 to 150 mm. Consequently, one sheet element’s useful area is between 1.60 and 1.64 m³.
When Ondulin is installed on a roof with a slight slope, the sheet overlap on the sides should be two waves, and the vertical overlap should be roughly 200 mm. This necessitates a unique calculation of the sheet material’s useful area.
It’s crucial to compute the roof before buying Ondulin, taking into account the usable area of sheet material, to avoid having to purchase goods from a different batch later on.
The fundamentals of roofing calculations
The forceps that are easiest to calculate have an inclination angle of 15 degrees, each slope of which is represented by a rectangle, and the overlap’s parameters are standard. In this instance, the roof area must be determined and divided into 1.6 m 2 of usable space for one Ondulin sheet.
If the complex roof needs to be calculated, it must be divided into separate planes (triangles and rectangles), the coating area for each plane must be determined separately, and the waste must be added to the product by 5% during installation.
The presence of windows in the roof plane, the usage of elements like yendov, horseback that cover the aprons, cornice grooves, roof ventilation elements, and other roofing system components should all be considered when calculating the roof materials. The computation of ondulin sheets is impacted by their quantity and presence.
The necessity of precise computations
Each leaf of ondulin obviously gains an area of about 0.3 m 2 in comparison to the total area of the standard sheet element; if this is not considered, the material purchased might not be sufficient for the installation of the entire coating.
An expert approach to the Ondulin roof calculations, accounting for the dimensions of the sheet elements, will prevent issues with the procurement and delivery of the missing material, which results in not only extra transportation expenses but also delays the work schedule. Furthermore, there’s a chance that the new Ondulin party won’t look exactly like the old one, which will make the roof look worse overall.

This roofing solution is a popular option for both professional builders and do-it-yourselfers because it not only improves structural integrity but also offers cost-effective benefits. This article tries to show how Onduline functions as a dependable and effective roofing option in various environmental and construction scenarios by looking at its advantages and applications."
Useful area of the Ondulin sheet.
The three types of sheets that make up Ondulin roofing materials vary in terms of their design, size, and usable area. Thus, for instance, Ondulin Smart sheets have a "smart" Smart Lock lock, Ondulin Diy sheets have fewer waves, and Ondulin Compact sheets are—you guessed it—smaller in size.
Without accounting for the end and side overflows, the Ondulin sheet’s useful area is an area. Once you know the useful area, all you need to do is divide the roof’s total surface area into a single sheet of useful area to quickly determine how much roofing material is needed. The roof’s slope determines the leaf ondulin’s useful area. The beneficial area of roofing materials increases with increasing angle of inclination and decreases when installed on gentle roofs.
The following factors are to blame for the shift in the advantageous area:
– the ondulin is mounted with the side overlap in one wave at large angles of inclination, and two waves at the low corners of the side overlap;
– the angle at which the roof of the end overlap of sheets slopes upward with an increase and downward with a decrease.
When there is a lot of rain, a braid of rain, and a strong side wind, leaks must be prevented by increasing the lateral and end overflows. Large overflows also stop leaks when forming lenses out of melted water.
Since the Smart Lock Castle adds another barrier to the water, the end overlap of the Ondulin Smart sheets is 12 cm and stays constant regardless of the angle of the roof tilt.
