At the stage of construction, you should especially carefully approach the roofing pies, because the roof very often experiences loads in the form of: precipitation, wind, various temperature differences. All these factors, very strongly affect the material of the roof. If poor -quality installation is performed, then serious problems with internal repairs may occur, and some discomfort may also be created. We need to know what the roofing pie from Ondulin will consist of. Because this material has gained wide popularity in construction.
Absolutely all roofing pies have the basis, because it is a rafter system that will have to be made as high as possible. To achieve this goal, we must draw up a preliminary project, taking into account absolutely all the materials that will be included in our pie. The rafter system should withstand not only this load, but also be sure to have an excellent strength of safety: in order to withstand the weight of snow, as well as a person who will be on it. We also need to include in the roofing pie, insulation. It must be laid out, between the bars of our rafter system, it is first necessary to pull the insulating film. As a heater, we can use either cotton wool or polystyrene, as well as other available insulating materials. Due to the thermal insulation system, warm air will not leave the room that will create very good living conditions, and also reduce the cost of heating. For vapor barrier, it is necessary to apply special PVC membranes, they are light and durable. If there is a special desire, then we can do wind protection. It can already be laid in a vapor barrier film, and there is also the opportunity to lay it separately.
The next layer will be the counter -rope, which will require continuous osp leaves. They will provide excellent air circulation, as well as allow you to create more comfortable microclimate in the house, they also give a strong and even surface to lay ondulin sheets. The crate from the OSP of the sheets must be laid with the interval, in about 1. 5 or 2 centimeters, between our plates. Instead of these sheets, we can apply plywood. In rare cases, a lining carpet is covered, which is capable of a bitumen coating. If we use a bitumen carpet, then we will save a roofing pie for at least 25 years. After these operations, we must lay the sheets of ondulin.
But additional elements in our “pie” will be ventilation, as well as the drainage system. If this is a residential building, then ventilation is simply necessary for us, excess moisture from the room will be removed with the help of it, as well as temperature differences, there will be no fungus, and also mold. The drainage system will take, all the moisture that has accumulated on the roof, thanks to this function, it will prevent any stagnation. Drains, can be performed in two versions, from tin and plastic.
This roofing pie will simply protect our home, from all kinds of natural factors, and will also provide an excellent microclimate inside the house, and will delight us for a very long time. Only high -quality building materials must be used, as well as observe all the necessary rules.
