AirGuard Sd5

AirGuard® Sd5 is a vapour control and water-proof membrane, which consists of DuPont Typar® spun bond and Ethylene-Butylacrylate Copolymer. AirGuard® Sd5 is used to prevent moist indoor air infiltrating into insulation layers in wall and roof constructions. This helps to avoid condensation, and eventually mould, within the insulation material. The membrane offers excellent tear resistance and is easy to place.

Applications

AirGuard® Sd5 is used as a vapour control membrane on the warm side of wall and roof constructions. Thanks to its constant moisture-inhibiting properties, AirGuard® Sd5 is suitable in buildings in climate class 2 and 3, such as homes, offices, schools, etc. AirGuard® Sd5 protects constructions against moisture and ensures an optimised and airtight insulation.

Processing

AirGuard® Sd5 should be applied to the warm side of roof and wall constructions. Use staples to attach the membrane to the underlying construction. It must be possible to read the logo from the inside. Keep an extra 100 mm at all horizontal and vertical overlaps. To ensure effective moisture inhibition, we recommend using Tyvek® tape to tape over staples, joints and overlaps. Use VAST-R® Butyl tape or Tyvek® FlexWrap tape to make openings and joints wind- and watertight.
