in - the size of the sheet and additional elements

Nobody follows building materials at random - this is at least unwise. Before buying, we always calculate how much is needed. So, for example, choosing ondulin for a roof, its sheet dimensions should be specified in advance. After all, taking an insufficient amount of material, you can, when you buy more, be very upset when you see that the color from the new lot is not at all the same, well, but you also do not want to overpay. Therefore, in this article, we propose to understand the dimensions of Ondulin and its additional elements, as well as to calculate the required amount of this material for the roof of a house.

We measure an ondulin sheet

French three-millimeter roofing with the name ondulin (or euroslate) basically has organic cellulose fibers. For durability and color preservation, the material is impregnated with bitumen with special additives.

In the process of manufacturing standard sheets with ten waves, the following deviations are allowed:

  • in the width of the sheet: from -5 to +5 millimeters;
  • the length of the sheet: from -3 to +10 millimeters;
  • by the wave height: from -2 to +2 millimeters.

And now the very parameters of the evoluer sheet:

  • The width of the sheet is 0.95 meters;
  • the length of the sheet is 2 meters;
  • the height of the crest of the wave - 3.6 centimeters
  • sheet thickness - 0.3 cm;
  • sheet weight - 6 kilograms.

When installing, you will need fasteners with accessories. In addition to special nails, curtain rods, valleys, gables, gutters and fillers for curtain rods, windows and roof fans will be needed. You should certainly take them all into account.

Determine the right amount of roofing

Usually, the company that will install the ondulin roof assumes these calculations. Usually she sells it. However, if you want to cover the roof with a euroslate yourself, then to calculate its amount of ondulin size and school knowledge in mathematics will be quite enough. You just need to represent the entire surface of the roof in the form of the simplest geometric shapes - triangles, rectangles, squares. Easily calculating the area of ​​each, we add them all - this is the area of ​​the roof.

And now the most important thing is to prevent the main mistake by taking “dirty” instead of “clean” sizes. Otherwise, it does not take into account the margin required for overlapping ondulin sheets. It is necessary, otherwise the quality of the roof will suffer. Therefore, a simple multiplication of length and width, giving a sheet area of ​​1.92 square meters, is not suitable for determining the consumption of material. After all, about 0.3 square meters from this sheet will go to the overlap.

Now more accurate calculations. When the roof is laid, the sheets of ondulin overlap not only in the longitudinal, but also in the transverse direction. The length of the overlap will be from 10 to 15 centimeters, and the width - one wave (9.6 centimeters). We get "clean" dimensions:

  • Length - from 1.85 to 1.95 meters;
  • width - 0.864 meters.

With these sizes of an ondulin sheet, its useful area will be less - from 1.6 to 1.64 square meters. And yet: do not forget that the edge of the roof will have to be cut, and the material will need 10% more. From these numbers, and push off, buying roofing.
