Warmup Insulated Underlay sits between the cold subfloor and the Foil Heater, reflecting heat upwards therefore making the underfloor heating system more efficient and effective. The foil backing acts as an effective moisture barrier. The Insulated Underlay has been specially developed for installation under the Foil Heater and Dual Overlay as part of a complete and stable system. The underlay is a thin polystyrene insulation barrier with effective acoustic properties to reduce contact noise.
The insulated Underlay and Dual Overlay make an ideal combination for installation of soft and resilient floor coverings such as carpet and vinyl over the Warmup Foil Heater.
Available in various sizes from Eco Friendly Heating and Flooring underfloor heating specialists.
