Why Install Warmup Underfloor Insulation?

Underfloor heating systems heat-up a room much faster than traditional centrally-heated radiators and require less energy to do so. To make your heating even more efficient and to save even more money on your heating bills, we recommend you also install Warmup Insulation to work alongside the floor-heater.

Underfloor insulation is important in reducing heat-loss whilst rapidly improving the heat-up times of a floor heating system. Many of our insulation solutions also feature soundproof and waterproof properties.

Benefits of Underfloor Insulation

Warmup insulation keeps the warmth produced by the heater inside the room, saving you both energy usage and money. As the underfloor heating system warms up to the optimal comfort temperature, the insulation enhances this heat and evenly distributes it into the room quickly.

For our Electric systems, Warmup Insulation Boards and Ultralight Insulation can be ordered separately and sit on top of the subfloor, acting as a secure base onto which the system can be installed. Most of our Hydronic Systems come with insulation panels as part of the overall system and typically utilise our Metro or Clypso Insulation. Warmup’s Total-16 System includes a built-in low-profile layer of insulation.

Greater energy-efficiency

The thicker the insulation below the floor heater, the greater the energy-efficiency, however deeper insulation will affect floor build-up height. Warmup Insulation products come in a range of depths and sizes to provide you with the optimal solution for your project to prevent energy-wastage.

Suitable for all subfloors

Our insulation products are suitable for use with all subfloors and can be used with all floor finishes. Some floor heating systems require a specific combination of insulation and accessories for a successful heating solution. Please find the details of these products below.

For use in any project

All our insulation products can be installed in new-builds or renovation projects.  For use in older properties with high levels of heat loss, a floor heater with insulation may not deliver the necessary heat output for optimal comfort.  We recommend carrying out a heat loss calculation as part of your project.

Underfloor Insulation Cost

All Warmup Insulation and Heating System Accessories are competitively priced and feature high-quality composition and a research-led design approach.

The exact price of the insulation depends on the size of your project and the heating system you are installing. The Insulated Underlay starts at £28.33 for a 2.5 sq.m coverage; the Insulation Boards are available from £19.16 per board and the Metro and Clypso Insulation panels are available in larger packs covering a greater floor area – enquire today for a quote for your project.

Whilst insulation may seem like an additional expense when installing a floor heater, the improved performance and energy-efficiency that the insulation provides more than makes up for this initial cost through the savings you can make on your heating bills.
