ThermalStream® – Incorporates flame retardant foam.
ThermalStream® is a new luxury carpet underlay for underfloor heating systems. It incorporates flame retardant foam for improved safety and features punched holes allowing a quicker heat transfer between the underfloor heating pad and your carpets. Most underlays for underfloor heating are thin (usually around 8mm thick) and sacrifice greatly on comfort underfoot. ThermalStream® is 10mm thick and wins the battle using clever technology which gives your carpet the softness it deserves without sacrificing on heat loss.
We also test to ISO International Standards and British Standards
As seen in CFJ & The Stocklist magazines – Wilsons Underlays voted Flooring Innovation Winners two years running (2022 and 2023)

Memory foam vs standard recycled foam
Why is memory foam better than standard foam? Well the graph speaks for itself, but simply – under compression testing, standard foam recovers 78% as opposed to our underlays which are up to 92%.
This graph also indicates our foams hold their thickness better in the long run which in return results in a longer life performance of your carpet, enhanced comfort properties underfoot and less furniture indentation marks.
