Isomass Isocheck Expandastrip Frame Seal 4000mm x 15mm x 8mm to 16mm

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.

Once unpacked and applied it will expand to fill the joint, including any irregularities or imperfections.

With its exceptional flexibility and elasticity, it is perfect for most unevenly surfaced components and is suitable for use with concrete, brickwork, steel, plastics, timber and fibrous materials.

Expandastrip is supplied in rolls that are mechanically compressed to one-sixth of their original thickness.

There is a self-adhesive coating to one side.

At its maximum expansion, it will provide a light air baffle.

Furthermore, when limited to 25% expansion of its compressed thickness, Expandastrip can provide a weather-tight seal against driving rain and wind.

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.
