Warmup Ultralight Underfloor Heating Board

Warmup Ultralight Underfloor Heating Board The Warmup Ultralight Underfloor Heating Board is a high-performance insulation board designed to improve the efficiency, heat distribution and responsiveness of electric underfloor heating systems. Its innovative 4-in-1 construction combines insulation, heat spreading, decoupling and sound reduction, helping to retain radiant heat within the room while providing a more even and faster warm-up. Designed as a low-profile solution for electric underfloor heating, Ultralight is just 6mm thick, making it particularly suitable for renovation and refurbishment projects where maintaining a low floor build-up is important. Its lightweight construction also makes the boards easier to transport, handle and install than conventional insulation boards. Key Features 4-in-1 underfloor heating insulation - Combines insulation, heat spreading, decoupling and sound reduction in a single board. Improved heat distribution - The integrated aluminium layer helps distribute heat more evenly across the floor surface. 50% more even heating - Warmup states that Ultralight provides 50% more even heating than standard insulation boards. 30% faster heat-up times - Helps electric underfloor heating reach the desired temperature more quickly. Low-profile 6mm thickness - Minimises the additional height added to the floor construction. Large board dimensions - Each board measures 800 x 1200mm, covering 0.96m². Lightweight construction - Each board weighs approximately 1.1kg, making transportation and installation easier. Dust-free installation - The board can be cut to shape using a standard utility knife without generating the dust associated with cement-coated insulation boards. Integrated decoupling layer - Helps protect tiled and stone floor finishes against potential damage caused by lateral movement in the subfloor. Sound reduction properties - Provides acoustic performance comparable to dedicated acoustic insulation materials. Suitable for electric underfloor heating - Designed for use beneath Warmup electric floor heating systems. 10-year limited warranty - Provides additional peace of mind for installations. Improved Underfloor Heating Performance Insulating beneath an electric underfloor heating system helps reduce heat loss into the subfloor, directing more of the generated warmth upwards towards the finished floor. This can improve system responsiveness while reducing the energy required to achieve the desired floor temperature. Warmup's Ultralight board incorporates an aluminium heat-spreading layer which helps distribute heat across the floor more evenly. Warmup reports 50% more even heating and 30% faster heat-up times compared with standard insulation boards. In Warmup's testing, an electric underfloor heating system operating at 150W/m² over an insulated screed took approximately 110 minutes to reach 27°C without Ultralight. With Ultralight installed beneath the heating system, the same floor temperature was reached in approximately 34 minutes. Actual performance will depend on the floor construction, insulation, heating system and room conditions. 4-in-1 Construction The Warmup Ultralight Underfloor Heating Board uses a multi-layer construction engineered to provide several functions within one low-profile board. The insulation layer helps reduce downward heat loss, while the aluminium layer assists with the rapid and even distribution of heat from the electric underfloor heating system. A decoupling fleece layer helps accommodate lateral movement within the subfloor, providing additional protection for tiled and stone finishes. Ultralight also incorporates sound-reducing properties, helping to reduce noise transmission through the floor construction. Lightweight and Easy to Install Ultralight has been designed to be easier to handle than traditional insulation boards. Its larger format means each board covers 0.96m², while the lightweight construction weighs approximately 1.1kg per board. The boards can be cut to accommodate corners, curves and other complicated areas using a standard utility knife. The absence of a cement coating also means the boards can be cut without producing the dust associated with many traditional insulation boards.

Its low 6mm profile makes it particularly useful for refurbishment projects where floor height is restricted. It can be used beneath a variety of compatible floor finishes and provides an effective insulation layer beneath electric underfloor heating systems. For tiled installations, the integrated decoupling layer also provides additional protection against movement within the subfloor. Installation Ultralight is installed onto a clean, dry and suitably prepared subfloor. Warmup recommends priming the surface with a solvent-free primer before applying a suitable flexible, cement-based adhesive. The boards are then positioned into the fresh adhesive with staggered joints. The boards can be cut to suit the shape of the room and around fixed objects using a standard utility knife. Installation should always be carried out in accordance with the Warmup installation instructions and the requirements of the chosen floor finish and underfloor heating system. Why Choose Warmup Ultralight? The Warmup Ultralight Underfloor Heating Board provides a practical way to enhance the performance of an electric underfloor heating installation without adding significant floor height. Its 6mm low-profile design, large 800 x 1200mm dimensions, lightweight construction and 4-in-1 performance make it suitable for both new installations and refurbishment projects. By combining thermal insulation, heat spreading, decoupling and sound reduction in one board, Ultralight provides a comprehensive foundation for a more responsive and comfortable electric underfloor heating system.
