Why is an air sealing tape important?
Air sealing tapes are tapes that provide a sealed building envelope. Eliminating unwanted airflow is the first win when it comes to improving a building’s energy performance. When a building is more sustainable with its energy, it is obvious to start with insulation. A structure is then fitted with insulation material to reduce heat loss. However, there is a difference between the theoretical insulation value and the realized insulation value. Insulation material must always be properly incorporated into a structure. That is, the end result of the overall construction is determined by its processing.
Gaps between insulation and structural members or interruptions when a facade connects to a roof, for example, are usually details that need to be properly sealed. You do that on the warm side with a vapor retarder film and on the cold side with a vapor-open film. With this, the large surfaces are air and wind tightly closed, which means that the first blow to prevent unwanted air flows has been made.
An overview of all our air sealing tapes
VAST-R® Total tape is a one-sided adhesive tape, which offers a universal solution for membranes and helps to give the building shell an airtight finish.
VAST-R® Non-woven tape is a one-sided adhesive tape that is made from non-woven polypropylene and features a VAST-R® high performance adhesive layer.
VAST-R® Nail sealing tape is a one-sided self-adhesive PE foam tape for creating a waterproof seal around (counter) battens used to fix roof membranes in place.
VAST-R® Membrane tape basic is a single-sided tape for making overlaps wind- and waterproof and to repair potential damage.
VAST-R® Facade tape features a facade membrane top layer, polyacrylate-based dispersion adhesive and a siliconized paper liner.
VAST-R® Double-sided tape is an extremely adhesive two-sided tape to give membranes an airtight finish and to make overlaps air- and windproof.
VAST-R® Butyl tape is a double-sided adhesive sealing tape that is used to stick membranes and films to various surfaces.
VAST-R® Aluminium tape basic is a single-sided adhesive tape for making overlaps wind-, air-, water- and moisture-proof and for repairing potential damage.
Tyvek® tape is a one-sided HDPE tape that features a thick layer of water-based acrylic adhesive and a siliconized paper liner.
Tyvek® FlexWrap tape is a flexible tape for making openings in roofs, ceilings and walls air- and waterproof.
Tyvek® Facade tape features a modified water-based acrylic adhesive and a siliconized paper liner.
TAFTEX® Membrane tape is a single-sided tape for making overlaps wind- and waterproof and for repairing potential damage.
TAFTEX® Facade tape features a modified water-based acrylic adhesive and a siliconized paper liner.
TAFTEX® Alu tape is a single-sided adhesive tape for making overlaps wind-, air-, water- and moisture-proof and for repairing potential damage.
Air thingies from Meuwissen Gerritsen
Airtight construction goes beyond just applying a foil. All interruptions or connection will need to be properly shut off. Consider, for example, overlaps of the film, the connection of the film to a window frame, or a penetration of a ventilation duct. In order to achieve airtight building effectively and easily, Meuwissen Gerritsen’s product range includes a range of tapes that help to carefully seal the building envelope on both the hot and cold sides. Depending on the desired processing, our tapes have different properties. Consider, for example, adhesion to various substrates but also applicability in difficult to reach structural parts or processing temperature.
