Roofing material ondulin: determine the useful width

In the case when it is necessary to determine the right amount of ondulin roofing material, some experts focus only on the overall dimensions of the sheets of material.

Principle of calculation

However, the technology of laying ondulin arranged crate provides that it is necessary to take into account the dimensions of the longitudinal and transverse overlap. As a result, the useful area of ​​the material used is reduced to 1.6 square meters per sheet.

For example, if you need to equip a roof that has an area of ​​100 square meters and a slope of more than 15 degrees, then you need 63 sheets of ondulin and 8 more ridge elements. True, such a calculation is correct when you need to lay the topcoat on a gable roof, which has a simple shape and does not have any architectural difficulties.

As a rule, the roofing material ondulin has the following parameters:

    1. One leaf of ondulin weighs 6 kilograms;
    2. The sheet length is 2 meters;
    3. The width of the sheet is 95 centimeters;
    4. The sheet has a thickness of 3 millimeters;
    5. The height of one wave is 36 millimeters.

Ondulin is lightweight and therefore can be stacked on an existing old roof covering.

If you opt for such a material for the roof, then you will have the opportunity to save on work on the preparation for the installation work.

Since the sheets are lightweight, then no need for reinforced flooring throughout the house. This is the advantage of ondulin compared to the finish coating of slate or metal. There is no need for a continuous crate, due to which the weight of the rafter system is reduced, and other materials are also saved.

Laying ondulin sheets

Lay ondulin sheets you can whole or they can be sawn into two or four parts. You will have the opportunity to combine with flowers and thus give your roof an individual look. Such actions will not lead to a violation of the waterproofing properties of the roof. Installation work can be done on our own, as Ondulin is an easy and easy to install material. At the same time, the service life of such a roof is extended up to 50 years or more.

Summing up the above, it can be noted that, when determining the useful area of ​​ondulin, the existing overlaps in the longitudinal and transverse directions of the sheets should be taken into account and the quadrature of the main material should be increased by them.
