For air tight joint sealing

Energy-saving thanks to absolute airtightness

ISO-BLOCO AIR is an absolutely air tight, pre-compressed and self-expanding joint sealing tape. With its proven hybrid technology, ISO-BLOCO AIR meets the requirements of the German Building Energy Act (GEG) for 100 % air tight building envelopes and joints. The thermal eduction function in the construction joint is enhanced due to the effective sandwich design. The most important key indicators for ISO-BLOCO AIR are the a-value of ≈ 0.00 m³ / [h · m · (daPa)2/3], the impermeability to driving rain of more than 750 Pa and fulfilment of the requirements of BG 1 and BG R in a single tape.
