Our Airtightness systems are the most efficient and reliable on the market. Manufactured by Dafa, a world leader in designing high performance sealing, absorption and protection products, our signature system, AirStop, supports the latest design in sustainable construction and energy efficiency, including Passive House standards. The AirStop system is the most well thought out system of vapor barrier solutions on the market.
The Dafa AirStop system consists of strong foils, vapor barriers and a comprehensive range of accessories to ensure optimum airtightness in your building. Used together, they guarantee the building is airtight. The decisive factor for sustainable building. The system can include plinth seal and sill foils, internal wall vapor barriers, window and door lining solutions, cable collars, vent/pipe collars, rafter collars, corner accessories and Dafa tape.
DAFA Airstop System is the guarantee for the good performance of your thermal insulation. It not only prevents the internal moisture from penetrating the thermal insulation, which can cause enormous problems (condensation, mold, etc.), but also prevents the air layer in the thermal insulation from remaining stable, which improves the energetic performance of the Building and living comfort increased.
DAFA Vapor Barrier Foils – are designed for use depending on the type of building and requirements relevant to the project. Different colours make them easily distinguishable. So you can always be sure that you are working with the right vapour barrier foil.
DAFA ProFoilTM – vapor barrier foil for professional building applications where high breaking strength during construction is critical. DAFA ProFoil is a CE marked, 100% virgin polyethylene (PE) material. The foil’s multilayer structure gives it high tensile and tear strength, despite only being 0.20 mm thick.
DAFA EcoFoilTM – is an environmentally friendly, 100% regenerated, CE marked PE vapor barrier foil. The foil is closed to diffusion, thus ensuring that vapor does not migrate into the structure. DAFA EcoFoil has high tensile and tear strength.
DAFA UniFoilTM – is a 100% pure CE marked polyethylene (PE) material. The foil has high tensile and tear strength, despite being only 0.15 mm thick.
DAFA HiFoilTM -is an intelligent, moisture-adaptive vapor barrier that adapts to the humidity conditions. If moisture builds up on the outer side of the vapor barrier, DAFA HiFoil wicks the moisture to the inner side, where it is dissipated via the building’s ventilation system.
DAFA DiFoilTM – is a vapor-permeable vapor barrier for building components ex-posed to sunshine, attics and periodically heated buildings. The vapor barrier allows periodically occurring condensation to pass through the foil, while sealing enough to stop normal vapor pressure.
