Concrete floor insulation

Certain areas in the home lose a lot of heat if they’re not insulated – concrete slabs are one example. While the slab itself is very effective at retaining and storing heat, warmth can escape around and under the slab if a thermal break is not created.

How it works

Insulation under concrete slabs is important because of the principle of thermal bridging. Basically this means that when materials with poor insulating qualities come in contact – such as concrete slabs and wooden floors or joints – heat loss will occur. The way to stop this is by creating a thermal break, a layer of material that conducts heat poorly and stops heat transfer between the two layers.

It is important to insulate not just under, but also around the sides of the concrete slab.

How it’s made

Under-slab insulation is usually made of polystyrene and is specifically designed for concrete slabs.

Why it’s good

• Moderate cost
• Enhances the performance of your underfloor heating
• Moisture-resistant
• Good thermal insulation properties

Is it safe?

There are no health or safety risks associated with the use of polystyrene under-slab insulation.

How much will it cost?

Concrete slab insulation will cost between $12 – $20 per m2 installed. this will be done as part of the construction process.
