ISO-BLOCO T-MAX is a special PUR sealing tape impregnated with a fire resistant polymeric dispersion. It is specifically designed for larger joints which require large movement accommodation. In addition to supplying a weathertight seal against wind driven rain it also has thermal and acoustic insulation properties, complying with UK Building Regulations.

ISO-BLOCO T-MAX is particularly well suited for multistory timber framed buildings where a large amount of differential movement is expected between fenestration or roofs and the external facades, allowing up to 39 mm of movement, with a single tape. Ideal for window head or cill and under roof eaves.
