Isowindow Airtight Foam

ISOWINDOW AIRSTOP FOAM is a specially formulated high density Pu foam designed for sealing of difficult areas such as pipe penetrations and openings, ideally suitable for masonry construction as well as timber frame; ISOWINDOW AIRSTOP FOAM is considerably denser than other non-airtight foams available on the market.

Due to the composition of ISOWINDOW AIRSTOP FOAM better insulating properties are achieved then other PU foams. ISOWINDOW AIRSTOP FOAM can be used with Airstop window tapes around Doors and Windows to offer higher insulation properties and air tightness.

ISOWINDOW AIRSTOP FOAM is highly suitable for around doors and windows, it will put pressure on the frame during expansion like other foams on the market , in addition to this it is moisture diffusing, this is an important fact when it comes to ensuring the longevity of wooden window frames in particular

Due to expansion and contraction as well as structural settlement particularly around openings such as doors and windows it is not recommended that it is used solely in these areas as a total airtight solution but part of our overall window sealing system.
