Product Description

Specialist Insulation for Masonry Cavity Walls

Dritherm 32 100mm is the industry-standard solution to insulating masonry cavity walls. At 455mm x 1200mm the slabs are sized to fit standard wall tie spacing, but can be easily cut to your own required dimensions. Each pack contains 6 slabs, which Knauf have designed to knit together to eliminate air gaps and ensure the best possible insulation and energy saving. While ideal for masonry cavity walls, the Dritherm 32 100mm is an all-around quality insulation, with a thermal conductivity of 0.032W/mK. This makes it a viable option as ceiling or ground floor insulation.

Built to last

Earthwool DriTherm Cavity Slab 32 Ultimate is a high density slab offeringKnauf’s 100mm cavity insulation is made from glass mineral wool, which is water repellent, rot proof and won’t encourage growth of fungi, mould or bacteria. Its quality construction and Euroclass A1 fire retardance means you can rely on it to keep your building warm and safe for years to come.

Insulation Slabs For Cavity Walls

Earthwool DriTherm Cavity Slab 32 Ultimate is a high density slab offering very high levels of thermal resistance for the thermal insulation in residential and non-residential masonry cavity external walls. The cavity slabs knit together when installed to leave no gaps in between that could make them less efficient. Easy to work with, they can be cut down to the size required with little effort and at 455mm wide they suit standard vertical wall tie spacing's, ensuring a closed joint with adjacent slabs
