Retrofit House Insulation Solutions for Existing Homes

A well insulated house - new or old - means less energy to heat and cool and improved comfort for you and your family. It will also reduce the risk of illness from damp, cold and mould.

About 10% of a home's heat can be lost through the floor, 24% through the external walls and a whopping 40% through the ceiling.

Insulation creates a thermal barrier to help keep heat inside the home in winter and to keep the heat out in the summer - making it a more comfortable place to live.

Insulating while renovating is cost effective, and will not break the bank!

Ceiling Insulation: Fresh insulation over existing
Underfloor Insuation: Remove foil insulation
Replace with: Fresh underfloor insulation
Ground Barrier: Vapour Barrier to minimise moisture
Acoustic insulation: New and existing internal walls
