Foil insulation

Contact us

If you are looking for an underfloor insulation system then our innovative foil insulation could be the perfect solution. Our ThermalDry underfloor insulation will keep your underfloor warm and dry which will lower the humidity in the living area of your home and therefore increase the temperature.

How our foil insulation works

Our underfloor foil insulation system is a plastic underfloor vapour barrier with bubbles on one side that act as thermal breaks and spacers to allow for drainage that stops water vapour from getting into your basement through the walls. In a nutshell, it acts as a wall waterproofing system for your underfloor that drains water away while insulating your underfloor.

When to use foil insulation

Our ThermalDry foil insulation system is the preferred option for you underfloor walls if you want to finish your underfloor now or in the near future. The ThermalDry foil insulation is mechanically fastened onto the wall using sealed plugs which help prevent any heat loss and puncture holes. This helps insulate your underfloor and will improve the heat retention within your whole property dramatically.

With the added benefit of helping to protect against radon gases and a 10 year basement and cellar guarantee you can sleep easy knowing that your underfloor issue will soon be fixed.
