Underfloor insulation

If your home sits on stumps and the floors are freezing in winter, underfloor insulation can help. It’s fitted from underneath, so your carpet and floorboards stay where they are.

A common sign

“Our floorboards are so cold we wear socks all winter.”
Cold air under the house draws warmth out through the floor. Insulating underneath stops that loss and makes rooms feel warmer underfoot.

About underfloor insulation

Warmer floors, warmer rooms.

Homes built on stumps or piers have open space under the floor, which lets cold air sit right under your feet. Underfloor insulation is fitted between the floor joists from below, slowing heat escaping through the floor.

The installer needs enough room to get under the house. They should also check for damp or poor ventilation under the floor, because those need sorting before insulation goes in.

Ask this

Ask them to check the space under the floor for damp and ventilation first. Insulation in a damp subfloor can make a moisture problem worse.
