ISO-BLOCO HF is an impregnated sealing tape, which under compression, is suitable for thermal and acoustic insulation as well as sealing against drafts and dust.

■  particularly ideal as a sealing and insulation layer in conjunction with the iso³-Window Sealing System
■  permanently elastic, providing a constant high level of acoustic and thermal insulation
■  vapour diffusion permeable - breathable
■  suitable for use as a sealing tape in construction joints
■  self-adhesive to aid installation/location
■  compatible with all established sealant compounds
■  low temperature expansion
■  constant quality control to ISO 9000 and DIN standards

ISO-BLOCO HF can be used between window couplings or in the perimeter joints between assorted building elements. It is also outstanding as a mastic bond breaker / backing rod or as a general sealant for internal use. However above all it is characterised for its thermal and acoustic insulating properties.
