Our bulk packs of Knauf Dritherm 37 are perfect for large projects. 75mm cavity slab insulation is a glass mineral wool insulation designed for insulating masonry cavity walls - ideal for extensions to older properties where cavities may be smaller than modern structures, or to be combined with other insulation methods to achieve a regulations-compliant u-value. 

75mm Knauf Dritherm 37 is designed to “friction-fit” within the entire width of a 75mm wall cavity, and is cut to fit between typical wall-tie spacings.
