ISO-BLOCO FILLER
The innovative masonry for cavity wall structures
ISO-BLOCO FILLER is a completely new kind of multi-functional insulation and sealing system which has been developed especially for window fitting in cavity walls. It is made up of two components: a highly elastic filling block which seals the masonry opening air tight and a sealing bar made of impregnated foam which provides reliable weather protection for the window connection joint in the rabbet area.
