Knauf Earthwool — Glasswool Insulation Batts

Knauf Earthwool is a soft, safe and easy to handle range of glasswool insulation batts suitable for residential and commercial applications. Available in a full range of R-values for wall insulation batts, ceiling insulation batts and roof insulation batts, Earthwool glasswool is one of the most widely used bulk insulation products in Australian construction. Its soft, non-itch formula makes it easier to handle and install than traditional fibreglass insulation batts, even in tight wall cavities and confined ceiling spaces.

Knauf Earthwool DriTherm — Cavity Wall Insulation

Earthwool DriTherm is a cavity wall insulation product designed specifically for double brick cavity walls — the most common external wall construction in Perth residential buildings. This silicone treated glasswool insulation provides an effective thermal barrier between external and internal walls, improving energy efficiency and reducing heat transfer year-round. Its moisture resistant properties make it particularly well suited to Perth's climate, where summer heat and coastal humidity place high demands on building insulation performance.

Knauf XPS — Rigid Foam Board Insulation

Knauf XPS is a rigid foam board insulation product suitable for a broad range of thermal insulation applications, including external wall insulation, green roofs, edge beams, basement walls and slab edge insulation. With excellent water resistance and high compressive strength, XPS foam board is one of the most durable rigid insulation board options available for both above ground and below ground applications.
