Description
Isocheck Expanda Strip is an open-cell polyurethane foam, impregnated with chemically stabilised acrylic and backed with a self-adhesive scrim tape.
Expanda Strip remains permanently elastic and once unpacked and applied will expand to fill the joint, including any irregularities or imperfections. Its flexibility and elasticity make it particularly suitable for most unevenly surfaced components and it is suitable for use with brickwork, concrete, plastics, steel, timber and fibrous materials.
Expanda Strip 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, Expanda Strip can provide a weather-tight seal against wind and driving rain.
Features and benefits:
- Excellent resistance to UV, mildew, and ageing and will not crack, split, bleed or dry throughout continuous movement cycles.
- Can be overpainted using any water-based acrylic or latex paint.
- Non-migratory and compatible with most caulking materials.
- Expandastrip is manufactured to ISO 9001 and approved to DIN 18542 and DIN 4102.
- Guaranteed life of 20 years.
