Application and typical uses of the product
NBT Pavaflex can be used in loft spaces, between rafters and within walls and floors in new build, renovation and conservation projects. It is not suitable for in-cavity
wall insulation or under ground floor slabs. The high density ensures excellent slump resistance while the elastic form maintains size and shape well while still allowing the flexibility to ensure a snug and complete fit
