Comfortzone Coated Insulation Boards

If you’re installing an underfloor heating system on a timber substrate, you’ll need a coated insulation board. This board from Comfortzone offers rigidity and strength to give stability for laying tiles, carpets or laminate flooring. Not only this, using insulation boards can also reduce your running costs by as much as 50% thanks to the minimisation of downward heat loss. Saving you money on your energy bills whilst providing a more efficient way to heat your home.

With a cement coating on both sides of the insulation board, it will give extra strength whilst also being 100% rot and waterproof, making it perfect for bathrooms/wetrooms.


• Single coated insulation board for use with timber substrates
• Choice of thickness - 6mm or 10mm
• Size of board: 1200 x 60mm
• Made using a high-density extruded polystyrene core with a polymer modified, glass fibre reinforced cement coating on both sides
• Rigid and super strong - perfect for providing stability for tiling
• 100% rot and water proof
• High thermal insulation properties - can reduce running costs by as much as 50%
• Eliminates downward heat loss
• Lightweight and easy to work with
• If using the 6mm board, fix to the substrate using a full bed of flexible tile adhesive - see recommended extras
• If using the 10mm board, you can fix using adhesive or screws and washers
• Ideally you’ll need to lay the boards across the floorboards at 90 degrees for maximum stability
