Why install Warmup Underfloor Insulation?

Underfloor heating systems heat-up a room much faster than traditional systems 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 and also rapidly improves the heat-up time of the floor heating system.

Benefits of Underfloor Insulation

Warmup insulation dramatically reduces heat-loss, keeping the warmth inside the room, saving you both energy usage and money. As the heater warms up to the optimal comfort temperature, the insulation enhances this heat and evenly distributes it into the room quickly. After the system clicks off, the boards help by retaining the heat in the space.

For our Electric cable systems, Warmup Insulation Boards can be ordered separately and sit on top of the subfloor, acting as a secure base onto which the system can be installed. They are 1/4″ thick and dramatically reduce downward heat loss.

Greater energy-efficiency

We believe 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 offer the optimal solution for your project to prevent energy-wastage without raising floor height too much.

Suitable for all subfloors

Our insulation product range offers options that 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 of our insulation products can be installed in new-builds or during 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.

Insulation for our Electric Range

Our range of insulation products enhance the energy-efficiency and response times of electric floor heating systems. Find out more about each product’s unique attributes below:

Warmup’s Insulated Underlay has been specifically designed to be used with the Foil Heater. The underlay reflects heat upwards and decreases downward heat loss, making the heating system more efficient. The product also acts as an effective moisture barrier.

Underfloor Insulation Cost

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

Warmup insulation boards are sold in full boxes. A box of insulation boards includes 6 4’x2′ boards. For this box, covering 48 sf, the cost is $231.00.

Warmup underlay is sold in a large roll. 1 roll of underlay covers 270 sf. The cost for this roll is $504.00.

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.
