Ideal for These Home Types
Underfloor insulation is particularly effective for certain types of Australian homes and construction styles.
Suspended Timber Floors
Perfect for homes with raised timber floors and accessible subfloor areas. The most common and cost-effective underfloor insulation application in Australia.
Older Homes with Underfloor Cavities
Heritage and older Australian homes often have large underfloor spaces that were never insulated. These homes benefit dramatically from retrofitted insulation.
Double-Storey Homes
Two-story homes with living areas above garages or other unheated spaces benefit greatly from underfloor insulation to prevent cold transfer.
