Ceiling and roof insulation

Heat rises, and in a home without enough ceiling insulation a lot of it goes straight out through the roof. Insulating the ceiling is one of the cheapest ways to make a house warmer in winter and cooler in summer.

A common sign

“We run the heater all day and the house still feels cold.”
If the warmth is escaping through the ceiling, a bigger heater won’t fix it. Insulation keeps the heat you’re paying for inside the rooms.

About ceiling and roof insulation

Stop paying to heat the roof space.

Ceiling insulation is a layer of batts or blown-in material laid across the ceiling, between the rooms and the roof. It slows heat escaping in winter and stops the hot roof space heating your rooms in summer.

Many older homes have none, or not enough. A good installer will check what’s already there, choose the right thickness for your climate, and keep insulation a safe distance from downlights and other fittings.

Do this first

Insulate before you buy a new heater or air conditioner. A well insulated home can often get by with a smaller system that costs less to run.

Not sure where to start?

Stop guessing, start saving: find your home’s energy score.

Don’t waste money on upgrades you don’t need. A professional home energy assessment shows where your house loses heat and power, so your budget goes where it makes the biggest difference.
