TYVEK DUPONT AIRGUARD REFLECTIVE 1.5 METRE X 50 METRE 12KG
DuPont AirGuard Reflective is an air and vapour control layer that is 100% airtight. It has a metallised surface with a very low emissivity internal vapour barrier that can enhance thermal comfort by reflecting up to 95% of radiant heat back into the building. It is usually installed with an air gap and can be installed on roofs, below ceiling levels and on walls. DuPont AirGuard Reflective provides effective condensation control for all building types, even for high-humidity structures such as swimming pools or textile factories, if installed continuously with all laps and penetrations sealed. Tyvek Metallised Tape is used to seal all laps, penetrations and cuts in the membrane and for connections to adjacent airtight layers at the roof and floor junctions. It can be installed either way, but its reflective surface must always face the airspace. The best method is to install it with the reflective side facing into the building, then fix a standard 25mm batten over the membrane.
