TP450 is a soft and flexible open cell polyurethane foam, impregnated with an acrylic based, UV stabilised resin with large joint size tolerance for large movement applications. The resin is water repellent and contains a fire retardant. TP450 has a self-adhesive side to aid initial location and is easy to apply in any weather. Additionally, TP450 has both thermal and acoustic insulation properties.


TP450 provides a weather tight seal against the most severe combinations of wind and rain, with particular suitability for sealing the head and sills of windows installed in timber frame construction and can accommodate up to 37 mm of differential movement within a max. 50 mm wide joint. Extensively tested with BBA accreditation, TP450 has a proven reputation across both the UK and Europe.
