Detailed product description
Iso Bloco One consists of impregnated, compressed PU foam with a special functional impregnation. The tape offers excellent temperature resistance from -30°C to +90°C and is suitable for installation conditions from approx. +5°C. The open cell structure ensures optimum vapour diffusion, while the impregnation enables high driving-rain tightness up to 1,000 Pa.
Compared with standard joint sealing tapes, Iso Bloco One combines three sealing levels in one product, reduces installation errors and increases energy efficiency. Typical areas of use are construction, industry, the trades and demanding DIY projects. For best results the tape should be chosen to match the joint width and laid evenly.
