Many homes are perfectly suitable for underfloor insulation. To help you find out if your house is suitable for underfloor insulation, ecoMaster has compiled a quick guide for reference.

Number 1: What type of floor is suitable for underfloor insulation?

Concrete slab flooring is not suitable for underfloor insulation. This is because underfloor insulation is installed from below the home, which means the installer should be able to access the space. A concrete floor won’t allow any access.

Timber floors are the most appropriate flooring type for underfloor insulation. Timber floors are supported by wooden joists, to which the insulation is easily stapled. Enclosed sub floors will need an access door to allow installation.

Consult with ecoMaster if you have steel joists.

Number 2: How much space is necessary to install underfloor insulation?

ecoMaster installers only need 40cm clearance under a floor to install the insulation. While many houses are not always built on an even terrain, it’s important that a large part of the house is 40cm above the ground for the installers to get under the floor without risk. For small sections that are lower than 40cm, the installation may require the tight area to be dug out to allow for more room.

Alternatively, solutions such as draught proofing may be considered.

Number 3: What about obstructions and joist spacing?

In addition to the 40cm clearance, there are other factors that will determine how difficult it will be to install underfloor insulation. For example, pipe works, ducting or cabling can make it hard to move around under the floor. Uneven joist spacing can also raise concerns as it requires a special installation technique to achieve perfect coverage.

Number 4: Dangerous deal-breakers

ecoMaster prioritises safety above everything else. There are a few situations where the risk outweighs all considerations, making the home unsuitable for an underfloor insulation installation. These include the presence of asbestos; large areas of rubble or stored materials under the floor; non AS3000 compliant wiring; and homes recently chemically treated for termites.

What will it cost?

The cost of underfloor insulation will depend on the size of the home. Contact ecoMaster with the size of your home in square metres and receive a pricing estimate for the installation.
