AlfaFlex is a single-sided, aggressive adherent film tape for a durable airtight sealing of vapour control layers at the thermal insulation. An airtight building shell saves energy and protects from construction damages.
AlfaFlex is universally applicable at roofing and interior construction and, thanks to its elastic and flexible foil, it is ideal to seal penetrations of the insulation level (e.g. exhaust pipes, electro pipes, rafters, cables etc.). Ideal for joints at building boards (e.g. OSB-boards).
Also best suitable for the sealing of penetrations and overlaps of roofing underlays!
