    Eliminating heat loss with Foamular XPS insulation in underfloor heating

    Austech External Building Products

    Foamular XPS insulation from Austech External Building Products is recommended for use with underfloor heating systems to eliminate heat loss and save energy.

    Heat loss can be expected from underfloor heating systems installed in thermally inefficient concrete slabs. Foamular XPS insulation presents the perfect solution for such installations by establishing a thermal lock that ensures the heat produced by the heating elements is transferred uni-directionally through the flooring where it is desired, rather than multi-directionally that allows heat to be absorbed and wasted in the sub-floor.

    Foamular XPS also enhances the performance of underfloor heating by maximising the temperature response when heat is needed.

    In the absence of Foamular XPS, it will be difficult to sustain floor warmth without a continual supply of energy to replenish the escaping heat. It’s therefore important to consider a solution such as Foamular XPS insulation before installing an underfloor heating system.

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

    Foamular XPS: A 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-borne bacteria or mould.

    Specifying Foamular XPS for underfloor heating applications

    The recommended material for underfloor heating applications is Foamular 300/30mm (R1.07) or FM 300/50mm (R1.78).  The insulation is required to be placed against the slab edge to 300mm below ground level.
