Tyvek AirGuard Reflective Vapour Barrier from DuPont - 50m x 1.5m Roll

This DuPont AirGuard Reflective Vapour Control Layer (VCL) is 100% airtight, perfect for roofs, ceilings, and walls. Its metallised surface has very low emissivity, reflecting up to 95% of radiant heat back into the building, significantly enhancing thermal comfort. When installed and sealed properly, it provides condensation control, suitable for high-humidity environments like swimming pools and textile factories. Using Tyvek Metallised Tape is recommended for sealing laps, penetrations, and connections to adjacent airtight layers. This high-performance reflective vapour barrier defends against heat loss via radiation and convection, effectively managing moisture and controlling interstitial condensation. It boasts a Class E fire reaction and is available in a 50m x 1.5m roll covering 75m. With an emissivity of 0.05 and a water vapor transmission (sd) of 2000m, this membrane can be applied to airtight suspended timber floors, wall constructions and various roof constructions..
