Foamular extruded polystyrene insulation available from Austech External Building Products is recommended for floor heating systems to help reduce heat loss and lower operating costs.

Placed below ground around the edge and under the concrete floor slab, Foamular extruded polystyrene insulation creates a thermal barrier to minimise heat loss, lowering operating costs and reducing energy demand.

Foamular is guaranteed to maintain its physical and thermal properties for 20 years. Being a closed cell extruded product, Foamular XPS will not rot or decompose in below grade applications.
