Insulation acts as a barrier to heat flow, and will therefore help to keep heat inside your home during winter. Insulating the walls, ceilings and under floors can increase the thermal performance of your home, helping to reduce energy bills by up to $450 per year.

Insulating your home is a simple and straightforward process that can be done over the weekend as a DIY project.

Up to 30 of internal air temperature escapes through the ceiling, so this is the best place to begin upgrading insulation levels. You should aim for the highest R-Value your budget will allow, in order to gain the maximum benefits. The higher the R-value, the better the thermal performance of your insulation.

Glasswool insulation provides high thermal and acoustic performance and is one of the most sustainable insulation products available. The Earthwool® range of glasswool insulation offers a super-soft option. Earthwool is easy to cut and handle, and contains no added formaldehyde.

All Earthwool products from Knauf Insulation are made using recycled glass and with ECOSE® Technology, which is based on rapidly renewable materials instead of petro-based chemicals.
