ISO-CHEMIE’s new ISO-BLOCO WIN2WALL has been specified by leading aluminium window and door installation specialists, Leeds-based Aluminium Frame Co Ltd.

WIN2WALL was specified for its thermal and acoustic benefits provided to complete a Schüco residential windows’ installation and the company has been so impressed by the multi-level tape’s performance that it will be specified for future work.

WIN2WALL combines excellent performance with competitive cost and is specifically designed for sealing the perimeter joint between windows, doors and walls.

The product enables quick and easy sealing from inside the building of gaps from 2mm to 8mm therefore accommodating the vast majority of UK window installations. It is supplied in two widths to provide the extra thermal insulation equivalent to A Rated (40mm tape) or A+ and A++ windows (65 mm tape).

Paul Clarke, owner of Aluminium Frame Co Ltd, said that WIN2WALL provided demonstrable installation improvements when compared to an alternative mastic sealant, and added:

“WIN2WALL is not only quick and easy-to-use but clearly offers improved all round airtightness and acoustic performance. It’s a good quality product that also delivers a neat finish to complement the good looks of the aluminium windows. We’ll definitely be using on future installations.”

WIN2WALL is weather tight to 600 Pa and has excellent acoustic insulation properties. Installing a window or door using the tape will give the window an equivalent or better thermal property than the window unit itself.
