- Warmup Insulated Underlay
Warmup Insulated Underlay is a thin insulation barrier that reflects heat upwards, making the underfloor heating system more efficient and effective. It also reduces contact noise and the foil backing acts as an effective moisture barrier.
Warmup insulated underlay has been specially developed for installation under Warmup dual overlay as part of a complete stable overlay system. It is the ideal duo for installation of soft and resilient floor coverings such as carpet, vinyl and linoleum, in combination with the Warmup foil heater.
Thanks to the structural integrity and design of the Warmup Insulated Underlay, a heat resistance of as much as 0.19 (Rm value)is achieved.
Features and benefits
- Resists heat loss and increases the efficiency of the underfloor heating system
- Extremely effective in reducing contact noise
- Very thin at only 6mm in depth
- Lightweight and easy to install
- Foil backing acts as a moisture barrier
- Recommended for use in combination with Warmup Dual Overlay, for best results under carpet and resilient flooring such as vinyl and linoleum

The Warmup Insulated Underlay is a thin insulation barrier that reflects heat upwards, making the underfloor heating system more efficient and effective. The insulated underlay has been specially developed for installation under the Warmup Dual Overlay system in combination with the Warmup foil heating system.
Ensure that the base is clean and dry. Install the insulation with the silver foil facing down. After fitting the first rows, roll out the next section of underlay. Remove the protective film from the self-adhesive overlap and stick both rows together, creating a damp proof situation.
Carpets and Underlays
Carpets and Underlay have a higher TOG value and a greater resistance to heat transfer, so it is important to choose carpets and underlays that have low Tog ratings. The thicker the carpet and underlay the longer the warm up time; this will have the effect of slowing the heat transfer of the flooring into the room. It is important to check the suitability for use with under floor heating. If you need to use an additional underlay ensure it has a low Tog rating, no greater than 0.8Tog, ideally 0.5 Tog.
Warmup Underlay and Vinyl Flooring
Vinyl Type Flooring This type of floor may be used over the Warmup Dual Overlay, but it is important to remember that high temperature adhesives suitable for underfloor heating must be used. When vinyl floor coverings are to be glued, fit the Warmup dual underlay and overlay 24 hours before.
NOTE: The maximum Tog rating for the carpet, underlay and the Warmup Dual Overlay should not exceed 2.5 Tog. When fixing carpet to the Warmup Dual Overlay it is recommended to use a tackifier adhesive or the double stick method of carpet installation. If using the stretch method of installation the gripper must be installed before the heating system. In order for the gripper to function correctly, the top surface of the gripper should be level with the top surface of the Warmup dual overlay system or insulated underlay. This can be achieved either by using an architectural gripper or a timber spacer under a conventional gripper to raise it to the correct level.
