Description
R8.0 Knauf Earthwool Ceiling Insulation Batts
Knauf Insulation has unveiled its latest innovation: R8.0 Ceiling Insulation Batts. Specifically engineered to comply with the new NCC 7 Star energy efficiency standards, these batts are designed to meet the rising demand for highly efficient insulation in Australian homes.
R8.0 Earthwool Batts are the thickest ceiling insulation batts available on the Australian market. Their added thickness allows them to extend over timber joists, effectively minimising thermal bridging and offering better performance than traditional double-layered systems.
Moreover, R8.0 Batts are quicker to install compared to the double-layer approach. Their greater thickness doesn’t complicate installation and removes the need for notching around joists.
