Main functions.

Using correct design structure and the combination of an under roof waterproofing layer, a vapor barrier and a suitable thermal insulation layer, can be provided on long time optimal properties roofing and wall structures. This applies mainly to the required parameters of the diffusion balance, conservation thermal resistance structures, ensuring the watertightness of the structure. At correct application underlaying films, due to their properties, ensure the waterproofness of the structure - both during the installation of the roofing, and as a waterproofing layer throughout the entire life of the roofing. The materials also ensure the release of water vapor into the outer space of the object. Thus, the melted snow, blown by the wind, rainwater or condensate will not disappear from the roof for inner material designs. At correct installation thanks to vapor-tight films, there is no moistening of the heat-insulating layers, which would lead to a significant increase in thermal conductivity. Therefore, the materials ensure a long service life of thermal insulation and prevent the occurrence of condensation in roof and wall structures, since water vapor does not penetrate into the dew point area in the thermal insulation space. In addition, the structure is air-tight and heat leakage is prevented. For connecting vapor barrier films, connectors are supplied. self-adhesive tapes UTAFOL SP 1 and UTAFOL SP AL,.

Material Handling and Transport

Transportation is carried out in clean vehicles. Despite the fact that each film and membrane is packed in polyethylene to avoid contamination, care must be taken during loading and other types of work so that mechanical damage and rupture of the film or membrane does not occur. Products are stored in a room where UV radiation does not reach. The materials can be used in structures where the temperature range in the material placement area is from -40 o C to +80 o C. It is recommended to connect vapor-tight and roofing films, membranes with a tape at a temperature above +5 o C.
