Underfloor Heating Insulation

Installing insulation in your home is a great way to keep the warmth produced by your heating system inside whilst preventing colder exterior air from getting in. In this guide, we’ll explore the many benefits of using insulation with underfloor heating, including how it can help to reduce the cost of your bills. You’ll learn more about:

  • How insulation reduces heat loss
  • The ways in which increased UFH efficiency results in cost-savings
  • Choosing insulation for electric floor heating
  • Insulation materials for water systems
  • How to buy insulation for your next project

Insulation enhances the efficiency of floor heating

If you’re thinking about underfloor heating for your upcoming home renovation project, then installing good quality insulation alongside your new heating system is vitally important. Losing heat through the floor is a common way for heat to escape a building, so a layer of insulation helps to prevent the heat produced by your system from escaping. Heat loss can be expensive as it wastes energy and means that you must keep the system on for a longer period of time for the room to retain its optimal comfort temperature.

Insulating the floor also ensures that an underfloor heating system will perform to its maximum efficiency. It will assist in promoting quicker heat-up times and evenly distributes the radiant warmth across the surface of the floor. This increased performance means less energy will be required to power your heating system, as the system will need to be on for a shorter period of time. The decreased energy usage will translate directly to your heating bill, saving you significant amounts of money. Insulation can reduce the overall underfloor heating running cost by as much as 50%.

The level of insulation needed in your home depends on the current levels of insulation. Recently built properties often have insulation within the ground floor, but older properties may not have this, so it’s worth checking the level of insulation of your home to ensure an efficient operation of the system.

Selecting the best insulation solution for your home

We offer a range of insulation materials for our electric and water floor heating systems and the best insulation for you depends on which system you’re installing and the perimeters of your project.

The best insulation for electric floor heating

For electric floor heaters, Warmup’s Ultralight Underfloor Heating Boards is an ideal insulation solution. These insulation boards provide 50% more even heating and 30% faster heat up times than standard boards and with this enhanced performance, you could save up to £16.50 / M2 per year on energy costs.

Our Insulation Boards provide a high thermal barrier to cold rising from the subfloor. Available in different thicknesses, this type of floor insulation allows you to choose the suitable level for your home – as a general rule of thumb the more insulation, the more efficient the system will operate, but the level you need will depend on the overall heat loss of your home. Ultralight and Insulation Boards are easy to install and can also be used to insulate walls without adding to the thickness of the wall significantly. They also have soundproofing properties meaning you can soundproof and insulate your home in a single step.

Designed specifically for use with Warmup Foil Heater, the Insulated Underlay helps to reflect heat upwards, making the system more efficient whilst also acting as a moisture barrier and helping to reduce contact noise too.

Finding your ideal water UFH insulation

Many of our water underfloor heating systems feature in-built insulation or can be purchased with accompanying insulation materials onto which the floor heating pipe will be attached to.

Warmup’s water Insulation is recommended for use with the Metro, Nexxa, Forte, Econna and Tectora systems. A wide range of compressive strengths are available to help support differing levels of load-bearing weight and the panels are available in a variety of thickness from 25mm – 100mm.

Our popular VLo Utra-12 Low Build System utilises insulation as part of its construction, resulting in an unparalleled slimline design of just 18mm, making it the perfect choice for all kinds of refurbishment projects.
