What is the roofing pies for the roof of ondulin

The choice of roofing pies should be treated very seriously and carefully, especially during construction. This is all very important because the roof constantly holds heavy loads, for example, such as temperature differences. All this can be reflected on roof materials. If the installation is poor -quality, problems with internal repairs may arise.

Many roof pies have a rafter system, which is performed very high quality. For this, a project must be drawn up in which all materials of the future pie should be taken into account.

The construction system must withstand the load, as well as have a sufficient margin of strength. The insulation is considered to be a mandatory component of the roofing cake. It should be laid between the bars of the rafter system and the vapor barrier film must be stretched first. Even in the role of insulation, there may be mineral wool or foam or other thermal insulation materials. Thanks to this, warm air will not leave the room for a long time and thus will create very good conditions for living. After the insulation, waterproofing will be used as which PVC membranes can be used.
