Innovative technologies declare the use of modern materials, which led to the modernization of the roofing system. The pitched roof is a complex multicomponent design that provides simple protection from the weather, maintaining the most comfortable temperature conditions, equalizing temperature and humidity levels in suspended rooms. High-quality vapor barrier of the roof can only be performed using modern materials. What are these hydro and vapor barrier materials for? First of all, they are necessary to protect the thermal layer from moisture absorption. As a rule, stone or mineral wool is used as insulation. It should be noted that the presented material easily absorbs moisture contained in the air, and this is an undesirable moment, since it loses its unique properties (for example, wetting the material at 5 percent gives a heat loss of up to 50%). In addition to all this, the temperature difference contributes to the formation of condensate, which has a negative effect on the insulation and metal structures. Hydro, vapor barrier will prevent the formation of condensate, protect the heater from the harmful effects of moisture on it. Conventionally, the above materials can be classified into the following types: anti-condensation films (waterproofing) and diffuse membranes.
Anti-condensation films are used for additional protection against rainwater flowing into ventilation inlets, roof leaks, etc. The presented material is mounted under the roof covering. Diffuse membranes - a unique material that has the ability to release water vapor that forms in the rooms and rises under the roof due to convection processes. Membranes should be installed on the inside of the insulation material. Innovative films combine diffuse and anti-condensation properties. They also include an absorbent layer that accumulates condensate water, and subsequently effectively evaporates it.
The vapor barrier of the roof depends on such an indicator as vapor permeability, that is, this is a property of the membranes that promotes the free exit of steam from the structure. Anti-condensation membranes are an indispensable material for the installation and arrangement of attics. Correct installation of a waterproofing film will provide effective ventilation of the insulation layer. The presented materials are laid on top of the insulation, so in this case the need for the formation of the so-called ventilation gap automatically disappears. With the use of vapor barrier membranes, it became possible to lay the insulation of the required thickness, which corresponds to the thickness of the rafters themselves.
The vapor barrier of the roof is carried out using modern vapor and waterproofing materials, which are produced in the form of film rolls, which greatly simplifies the installation process, makes it possible to seal the edges when overlapping, and reduces the number of seams. These materials are used in the installation of any roofing systems from ceramic to composite. As a result, vapor barrier of the roof will improve the protection of the roofing material, improve thermal insulation and extend the operational life of the structure. Steam and waterproofing materials of the following brands are especially popular: Derken, Monarflex, Clober, Tyvek. The vapor barrier of the roof can be made using other heat-insulating materials, the choice on the market is very large, so it will be easy to choose materials with the required vapor permeability - for the calculated specific individual conditions of one or another object.
