Thermal Stream Underfloor Heating Carpet Underlay

(5 customer reviews)


SKU: ThermalStream Roll Category:

Product Description

ThermalStream is perhaps the best underlay for underfloor heating. It’s thickness of 10mm makes it really soft to walk and it uses flame retardant foam with punched holes allowing a much quicker heat transfer between your underfloor heating and your carpets.

You can buy other underlays for underfloor heating but these are mostly rubber underlays which are thin and give very little softness underfoot – ThermalStream is changes the whole concept with new technology.

Thickness: 10mm
TOG: 1.1 approx.
Roll Size: 15m2 (11m x 1.37m)
Foam: Flame Retardance
Comfort: 5*

5 reviews for Thermal Stream Underfloor Heating Carpet Underlay

  1. John Westfield

    I’m a fitter and really impressed with this. I’ve mainly used Heatflow or King in the past but this stuff feels far better to walk on. Good to see new & better products on the market. Will be using this again – Thanks John.

  2. Megan Rushton

    Made our carpets feel soft to walk on vs other underlay we have in the house. Worked well with our underfloor heating too – ours is water pipe system which connects to our boiler.

  3. Arthur D.

    Bought this underlay twice now, worked very well in both rooms and carpet feels soft so does what it says on the tin!

  4. Jessica Drayton

    Very nice underlay and works a treat on our new Westex Carpet with electric UFH system. We were going to go with the shops thin rubber underlay which felt very hard to vs normal foam underlays, but after doing some research, this underlay is far better. The holes in the underlay also have made a big difference to heat transfer to the carpet so we only have to keep our settings on 50% capacity which is a big plus on energy savings monthly.

  5. Roger Field

    This has been down 6months now and still feels better than our carpets in the other room, i’ve just bought another roll to do the next rooms – wife loves the softness feeling of the carpet now.
