125mm Earthwool DriTherm 32 Cavity Slab is a semi-rigid insulation material made from non-combustible, water repellent, glass mineral wool. They are 1200mm x 455mm wide to suit standard vertical wall tie spacings, ensuring a closed joint with adjacent slabs. Manufactured with Knauf ECOSE Technology – no added formaldehyde binder, which is up to 70% less energy intaensive than traditional binders and is made from rapidly renewable bio-based materials instead of petroleum-based chemicals.
TB4000 is targeted at cut-to-fit applications between rafters or joists and enables users to achieve lower U-values with a single layer of insulation than has previously been possible. It is also appropriate for use in floors and walls. With low emissivity foil facings, TB4030 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP).
