100mm Knauf Earthwool DriTherm 32 Cavity Wall Insulation Slabs are an effective thermal solution for insulating external wall cavities. These 100mm Earthwool semi-rigid glass wool slabs are designed as a full fill cavity solution and can be used in buildings up to 12m high due to their A1 non-combustible classification. The 32 relates to the product's thermal conductivity value of 0.032 W/mK, which is the lowest and most thermally efficient of the Knauf DriTherm range. Made using Knauf's unique ECOSE technology, as well as a water repellent additive, Knauf DriTherm 32 100mm cavity insulation slabs are soft to the touch and provide excellent protection for the lifetime of the building. They are cut at 455mm wide in line with standard wall tie spacings, producing a closed joint with the adjacent slabs.
