## Overview

CosySpace XPS Boards are 6mm thick extruded polystyrene insulation sheets designed for underfloor heating on concrete floors. Their closed-cell structure provides excellent thermal insulation by reflecting heat back to the floor, improving energy efficiency and reducing heating costs. Lightweight, water-resistant, and recyclable, these boards resist compression, aging, and damp, making them a durable, eco-friendly choice for modern insulation needs.

## Description

Note: Please note that the product colour for 6mm and 10mm boards can be blue or black depending on what stock is available. CosySpace XPS Insulation Boards are manufactured from fully recyclable materials. They are produced from foamed polystyrene, a material that does not deteriorate. The cell structure in the board is built up from very fine closed cells that give the product its excellent physical and mechanical characteristics.An excellent insulation that saves energyThis special cell structure means that the sheet does not conduct heat. When you lay CosySpace XPS boards as an underlay any heat from your room or floor will be reflected back towards the floor surface. This is because you will not be wasting heat through your floor and will utilise your energy in a very green efficient manner, thereby lowering your energy consumption and carbon footprint.Effective protection against cold and dampCosySpace XPS boards do not only take care of the heat, they are also an effective guard against the cold and damp. The cold will be held back by the non-conducting characteristics of the foam and as the CosySpace XPS board is also water repellent, it will not rot or go mouldy and will help hold back any damp from your floor. CosySpace XPS boards are also resistant to cement, plaster, and most alkalis (lime or soda), however, not against organic solvents (i.e. acids)

Review: Perfect for under floor heating - - Specially built for under floor heating - easy to cut for different sizes - package arrived much sooner than expected so that we could start the work! only downside is that they were slighly different sizes. Overall quite pleased.
Review: Did the job... - ....but the sizing wasn't exactly the same on all boards. We used them under 9mm ply so the gaps got covered up but would have been nice to have them all uniform. I would recommend though - it's not as if you see them after the work is done...
