Advantages of the ventilated roof
The most well-known options for roofing are:
- roll roofing (simple and inexpensive, but unstable to the processes of decay);
- roofs of sheet materials (slate, metal, evroshifer - service life reaches 40 years);
- membrane roofs (good load strength);
- coatings made of piece materials (ceramic tile - durable and environmentally friendly);
- Roof sandwich panels (good strength and temperature properties, but the service life is limited to 30 years).
When installing roofs, two problems arise. First, with continuous gluing, it is necessary to remove the old material that is saturated with moisture. Secondly, the blistering from air bubbles remaining after installation leads to ruptures and leakage of waterproofing. This is due to residual moisture accumulated in the insulation. You can order a turnkey roof on the website www.roofkey.ru.
Problems can solve the ventilated roof, which has additional layers. Consider, for example, a flat roof.Here, the para-insulation does not allow the warm air to penetrate from below into the insulation, so moisture does not accumulate in it. The bias layer is designed to remove moisture in case of damage to the waterproofing. Greater efficiency of such coatings is provided by the presence of ventilation from the inside.
The advantages of the roof with a ventilated roof include:
- ease of installation;
- cost savings during renovation;
- swelling of the roofing is excluded;
- resistance to temperature extremes, frost, ultraviolet radiation.
There are such coatings and disadvantages:
- air flow under waterproofing contribute to a large loss of heat, therefore, a large thickness of insulation is required;
- hit in a layer of humid air in the summer.
