## Overview

CosySpace XPS Foam Insulation Boards are high-performance extruded polystyrene sheets sized at 1200x600x6mm, designed to optimize underfloor heating efficiency and thermal insulation. With a compressive strength of 300 kPa and thermal conductivity of just 0.029 W/mK, these lightweight, moisture-resistant boards provide durable, eco-friendly insulation that reduces energy consumption and protects against cold and damp, making them ideal for modern, energy-conscious homes.

## Description

Note: Please note that the product colour for 6mm and 10mm boards can be blue or black depending on what stock is available. The CosySpace XPS Insulation Boards are eco friendly as they are manufactured from fully recyclable materials.They are produced through a plastic extrusion process to form polystyrene insulation sheets, 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. These XPS boards are also resistant to cement, plaster, and most alkalis (lime or soda), however, not against organic solvents (i.e. acids)SpecificationsBoard Size - 1200mm x 600mmThickness Available - 6mm, 10mm and 20mmHigh compression resistanceAble to resist repeated freeze and thaw cyclesMoisture proof and Air tightSound Reduction of over 22dbNon-absorbentCorrosion proofLow thermal conductivityStructurally stable in the long runTechnical detailsDensity: 40kg/m3Compressive strength: 300 kPa (this equals to 43.51 pound force per square inch)Thermal conductivity:0.029 w/mk
