Calculation of the number of sheets of Ondulin on the roof

Determining the quantity of Onduline sheets required for your roof is crucial to the success of your roofing endeavor. Popular roofing material Onduline, which is cost-effective and long-lasting, is available in standard sheet sizes that, when installed properly, cover a predetermined area.

First, take precise measurements of your roof’s dimensions. The width and length of each area where Onduline sheets are to be installed are included in this. To simplify computations for roofs with intricate shapes, divide the area into smaller rectangles or triangles.

Next, find out what size Onduline sheets are available where you live. These sheets usually have standard dimensions, such as 2 meters by 0.95 meters, or something comparable. For exact measurements, check with your supplier as they may differ slightly.

Divide the total roof area (measured in square meters) by the area that one Onduline sheet covers to determine the quantity of sheets needed. To calculate the required number of sheets, divide the total roof area by 1.9, for example, if each sheet has a surface area of roughly 1.9 square meters.

It’s a good idea to take extra sheets into account in case of overlaps, cutting waste, or unforeseen circumstances. This guarantees that you have sufficient material to finish the job quickly and without having to make additional trips to the supplier.

Features of the Euro -Shifle

Pressed cellulose is used to make wavy bitumen slate. Apart from bitumen impregnation, the roof coating is enhanced with a protective-decorative layer made of ceramicized granulators or mineral crumbs, as well as thermo-adopted resins.

The ease of installation of ondulin is determined by its structure:

• Sheets have a low weight (about 6 kg);
• Euro -shifers 3 mm thick is easily cut with standard tools (knife -off wood, electric saws);
• The coating of wavy sheets is attached by means of roofing nails with a sealing gasket or self -tapping screws.

With the help of Onduline’s roof material, you can perfectly coat a building to protect it from outside influences. When installed correctly, roof flooring can withstand heavy snow loads, powerful wind gusts, and rain-induced moisture transfer.

Ondulin’s coating has a 15-year warranty; however, its real life may extend to 50 years.

High-quality, totally safe for human health components are used in the production of Euro-shifers. Different parts of the material may have slightly different shades because the appearance of the coating is somewhat dependent on the characteristics of mineral pigments. It is best to use ondulin from a single batch so that the color of the roof is uniform.

To precisely calculate the number of sheets needed for the euro-shifter, preliminary calculations must be done correctly.

Principles of calculating ondulin on the roof

The useful area of the working sheet must be determined before ondulin on the roof can be calculated. The size of the overlaps during installation determines this indicator. The vertical overlap ranges from 150 to 300 mm, while the side overlap occurs in one or two waves.

Since a roof with a small angle of inclination experiences maximum snow loads, it is crucial to maintain the maximum strength of the rafter structure and provide a continuous crate if the angle of slope of the roof does not exceed 10 degrees.

The ideal cutting board is for a continuous crate. The side overflow of two waves is installed on the roofing flooring; the vertical overlap should extend at least 300 mm.

When dealing with roofs that have slopes between 10 and 15 degrees, the snow load is less, so using a crate made of bars or boards laid in 450 mm steps (measured along the axes of the crate’s details) is sufficient. The vertical overlap of the euro-screen should be 200 mm, and the side overlap should be one wave.

The step of the discharged crate rises to 600 mm when the slope’s angle surpasses 15 degrees, which is the most common occurrence. One wave makes up the side overlap, and a 150 mm vertical overlap is possible.

A typical leaf ondulin measures 950 mm in width and 2000 mm in length, with an area of 1.92 kV. m. The size of the overlaps should be subtracted from these values in order to calculate its useful area.

The useful area of bitumen slate sheets varies based on the parameters of the roof slopes’ tilt angle, and can be approximately 1.3, 1.5, or 1.6 square meters.

Calculating the amount of sheet material

You can calculate the useful area of the euro-shifter sheets by knowing the angle of inclination of the roof’s slopes. This indicator should be computed independently for slopes at various angles if the roof has a complicated shape.

The roof area must be divided into a useful area of one coating element in order to determine the number of sheets needed to lay the roofing.

Typically, the roof slope is shaped like a triangle, trapezoid, or rectangle. Mathematical formulas are all that are needed to determine the slope area. The total area of a complex roof is determined by adding the areas of all of its slopes.

Roof areas should not be determined by the structure’s dimensions, but rather by the lines of cornice overhangs!

Finding the ideal value of vertical overflows for a specific roof will help you avoid having a lot of scraps when installing the coating from the euro-shifter. They may surpass the suggested limits for slopes that have an inclination of any kind.

It is not advisable to make the upper row of non-nicious stripes because the skate element’s 200 mm overlap will reduce the row’s visible portion and detract from the roof’s overall aesthetic appeal.

If the roof is simple, then an additional 10% must be added to the calculated amount of sheet material; if the roof is complex, meaning there are many angles, adjacents, and transitions, then an additional 15% to 20% must be added.

Don’t forget to account for yndovs, skates, and other components that call for the use of branded coatings from ondulin manufacturers when calculating the material needed for roof installation or repair. Aprons are used around roofing windows, chimneys, and other structures.

The computation is done based on the skate’s length, yends, forceps, and adjacency.

Calculations are involved if the goal is to apply an original coating to the roof using sheets of different colored Euro-strop. Drawing a large-scale color scheme and tallying the number of sheets in each color is the most practical method.

One can use a specialized program or calculate the roofing materials from ondulin on their own.

The number of Onduline sheets required for your roof must be determined in order to guarantee a seamless and effective installation procedure. Take precise measurements of your roof’s dimensions first. In order to account for any overhangs or extra features like dormer windows, this takes into account both the length and width.

Once the measurements are known, refer to the Onduline sheet manufacturer’s specifications. The coverage area of each sheet is usually included in these specifications. To find the number of sheets you’ll need, divide the total roof area by the coverage area of one sheet. It is advisable to include a tiny buffer, say 5–10%, to account for any cutting errors or losses during installation.

When calculating, take the roof’s shape and layout into account. More sheets might be needed to completely cover all the areas on a roof with intricate shapes or many angles. If the slope or sections of your roof differ, figure out how many sheets you’ll need for each section separately.

Finally, find out if Onduline sheets are offered in packs or bundles when making a purchase. By using this packaging information, you can make sure that the right amount is ordered. Recall that having a few extra sheets is preferable to running out during installation. You can calculate and buy the appropriate quantity of Onduline sheets for your roofing project with confidence if you follow these steps.

The article "Calculation of the number of sheets of Onduline for your roof" on the "All about the roof" website will walk you through the simple process of figuring out how many sheets of Onduline you need. You can precisely estimate the number of sheets needed for your roofing project by following a few easy steps and using basic measurements of the dimensions of your roof. With the help of this guide, you can make sure you buy the correct quantity of Onduline without having to worry about overspending or hassle.
