Window installers can now take advantage of the new ISO-BLOCO WIN2WALL multi-level sealing tape from ISO-Chemie, which combines excellent performance with competitive cost and is specifically designed for sealing the perimeter joint between windows, doors and walls in the UK.


Not only does ISO-BLOCO WIN2WALL enable windows and doors to be quickly and easily sealed from inside the building, the product will seal gaps from 2 mm to 8 mm, which will accommodate the vast majority of UK window installations, and will come in 2 widths to give the extra thermal insulation equivalent to A Rated (40mm tape) or A+ and A++ windows (65 mm tape)

Among the key advantages of WIN2WALL are not only its thermal performance, but it is also weather tight to 600 Pa (Violent Storm Force 11) and has excellent acoustic insulation properties. Installing a window or door using WIN2WALL will give the window an equivalent or better thermal property than the window unit itself. Even the smaller 40mm size tape will give the joint between the window and wall a U-Value of 1.2, equivalent to an Energy A-rated window.

Other comparable size tapes on the market will not match the 1.2 U-value or the performance of an A-rated window. The larger WIN2WALL size tape will give an U-Value of 0.7, which is even better than a triple glazed Passivhaus standard window. WIN2WALL is applied to the window prior to installation and has very slow expansion speed to give ease of installation for large windows or even patio doors.

WIN2WALL also complies with the Zero Carbon Hub project by using materials that fill the gap between ‘designed performance’ and ‘built performance’ to give a guaranteed on site performance. This makes WIN2WALL particularly useful to new build developers who are looking for excellent and consistent performance across potentially large installation projects.

Ultimately, ISO-BLOCO WIN2WALL offers the installer a more straightforward installation in all weather conditions and the end user reduced energy bills.

Along with ISO-Chemie’s ISO-BLOCO ONE sealing tape, WIN2WALL is also permeable to outward moving vapour diffusion according to the RAL principles of 3-level sealing and is more air tight on the inside than the out. This guarantees that the joint will dry out completely.

ISO-Chemie will launch ISO-BLOCO WIN2WALL during UK Construction Week 2015 at the Build Show, taking place on 6-8 October 2015 at Birmingham’s NEC, Stand B3/240.
