Tyvek AirGuard Smart
Tyvek® AirGuard® Smart is an airtight variable vapor barrier, which consists of HDPE Tyvek® and features a polymer coating. Tyvek® AirGuard® Smart offers high moisture-resistance in the winter and low moisture resistance in the summer. As a result, Tyvek® AirGuard® Smart is ideal for constructions where the cold side offers no or very little breathing properties. The active layer adapts to the relative humidity and will expel moisture outdoors in the summer if it has become entrapped within the construction.

Applications
Tyvek® AirGuard® Smart is used as a vapour control air seal on the warm side of wall and roof constructions. Thanks to its variable moisture-resistance (Sd rating), Tyvek® AirGuard® Smart is perfect for flat roof constructions where insulation (mineral wool) has been applied to the underside. The Tyvek® base ensures lightweight, strong, tear-resistant and extremely effective protection for insulation material. Tyvek® AirGuard® Smart is not suitable in damp areas, such as bathrooms and indoor pools.
Processing
Place Tyvek® AirGuard® Smart on the warm side of wall and roof constructions. Use staples to attach the membrane to the underlying construction. It must be possible to read the logo from the inside. Keep an air cavity (for ventilation purposes) between the membrane and the wall or roof finish. Keep an extra 100 mm at all horizontal and vertical overlaps. To ensure an effective air seal, we advise using Tyvek® FlexWrap tape and Tyvek® tape to make overlaps, joints and openings moisture-repellent.
