Warm insulation side
Vapour control membranes

AirGuard Sd23

AirGuard® Sd23 is a vapour control and watertight membrane, which consists of DuPont Typar® spun bond with a polypropylene coating. AirGuard® Sd23 is used to prevent moist indoor air from 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® Sd23 is used as a vapour control membrane on the warm side of wall and roof constructions. Thanks to its constant moisture-inhibiting properties, AirGuard® Sd23 is suitable in buildings in climate class 2 and 3, such as homes, offices, schools, etc. AirGuard® Sd23 protects constructions against moisture and makes sure that insulation material is perfectly airtight.

Processing

AirGuard® Sd23 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.
