6mm XPS Insulation Board (Styrofoam LBH-X-P)

Maximise the efficiency of your heating system without sacrificing floor height by using our premium 6mm XPS insulation boards.

6mm XPS Insulation Boards FAQs

Do I need insulation boards with my underfloor heating mats?

While it isn’t a necessity, we strongly recommend having insulation boards under your electric underfloor heating mats. These mats help to reduce the amount of heat that is drawn down into the subfloor, meaning you will experience more efficient heating.

Can I use these boards in a bathroom or a wet room?

Yes, you can! Because XPS insulation is water-resistant and doesn’t rot or degrade when it comes into contact with moisture, it’s a great choice for bathrooms and wet rooms as long as proper waterproofing measures are implemented.
