Impact Plus Thermal Insulation Underlay is the perfect choice for use under wood, laminate and carpet floors with or without underfloor heating fitted over. It is fully water, vapor and draft proof so blocks out the cold from below. This insulation also greatly reduces impact and airborne noise levels between rooms above and below. At only 6mm thick it will not build your floor height up to much, is light weight easy to cut and simple to lay.

Impact Plus Thermal Underlay

Laminate Insulation for use with our 150w Aluminium Foil heating systems will maximise the efficiency of the foil heating system.

Impact Plus Insulation provides an acoustic layer beneath the Foil mats, providing a perfect cushion for the heating to lay on. Therefore, making it the recommendation for any Laminate or Wood floor that is 8mm in depth or above.

** If installing under an LVT or Karndean floor, then XPS thermal board should be used **

Made from a high-grade closed-cell acoustic foam, designed to replace the cheap and thin underlays typically provided with wood and laminate flooring.

Our Impact Plus thermal insulation has been designed to provide a high thermal barrier between the subfloor and foil underfloor heating system when used with our Aluminium Foil underfloor heating, Impact plus thermal insulation greatly increases the efficiency of your system.

This drastically reduces your underfloor heating system’s heat loss and running costs. Importantly it will protect your heating and its warranty under the final floor, which standard underlay may not.


Impact plus insulation is manufactured in compliance with BS EN ISO 9001:2001. And is certified by the BBA Certificate 04/4186. Our Impact Plus insulation complies with BS and EN 13164:2001 certifications. Thermal insulation products for buildings.
