ISO-BLOCO HYBRATEC - Expanding tape (55/6-40 mm) (10 m)

Multifunctional Tape with Integrated Foil Barriers

ISO‑BLOCO HYDRATEC combines the quality features of high‑performance window joint films with the advantages of MF 1‑certified multifunctional sealing tapes (formerly BG 1 and BG R certified). This hybrid technology delivers excellent air impermeability and driving‑rain resistance from the film layers alongside the high expansion force and long‑term movement accommodation of pre‑compressed soft PUR foams.

RAL‑Compliant Multifunctionality

With an a‑value of 0.00 m³/(h·m·daPaⁿ), ISO‑BLOCO HYDRATEC is 100 % airtight on the inside, eliminating heat loss by convection. Its functional core offers high sound and thermal insulation, and its weather‑protection layer withstands driving rain up to 1050 Pa—well above average. Multiple integrated barrier layers follow the RAL principle: “inside tighter than outside.”
