Isomass Isocheck Expandastrip 5 To 9mm Thick Door And Window Frame Seal 18mm X 4m – 20 Rolls

Isocheck expandastrip is an open cell Polyurethane foam, impregnated with chemically stabilised acrylic and backed with a self adhesive scrim tape.

Expandastrip remains permanently elastic and once unpacked and applied will expand to fill the joint, including any irregularities or imperfections. It’s exceptional flexibility and elasticity make it ideal for most unevenly surfaced components and is suitable for use with brickwork, concrete, plastics, steel, timber and fibrous materials.

Expandastrip is ideal for joints between precast units, sealing around doors and window frames, or between corrugated roofing panels, roof structures and roof lights ventilation and air conditioning ductwork. Expandastrip is also used as a primary or secondary seal in vertical and horizontal joints of building facades as well as metal painted cladding systems, window perimeter curtain walling and skylights.

Expandastrip is supplied on rolls compressed to one sixth of its original thickness and supplied with a self adhesive coating to one side.

At its maximum expansion it will provide a light air baffle, however when limited to 25% expansion of its compressed thickness, expandastrip can provide a weather tight seal against wind and driving rain.
