Without Foamular XPS, sustaining floor warmth will require the continual supply of energy to replenish escaping heat. With unstable and ever increasing energy costs, Foamular XPS insulation is the solution. Before you finalise your plans to install underfloor heating, be sure to consider what you are placing under the underfloor heating.

How to Create a Continuous Thermal Barrier with Foamular XPS

When placed under the slab and around the exposed perimeter, Foamular XPS creates a continuous thermal barrier, limiting temperature fluctuations, reducing heat loss and prolonging the life of the Underfloor Heating system.

For maximum performance Foamular XPS is laid against slab edge, over the flat floor areas and into trenches prior to concrete pour. Foamular XPS is a lightweight and easy to handle insulation which is simple to cut and trim and does not require the use of special power tools during the installation process.

Foamular XPS: High Performance Product

Foamular XPS maintains a 20 year 90% thermal properties guarantee even when covered by concrete, giving the consumer long-term energy and environmental savings. Foamular XPS is not affected by moisture, soil born bacteria or mould.

How to Specify Foamular XPS for Underfloor Heating Applications

The recommended materials for Underfloor Heating applications is Foamular 300/30mm (R1.07) or FM 300/50mm (R1.78). The minimum requirement is for the Insulation to be placed against slab edge to 300mm below ground level.
