## Overview

CosySpace XPS Foam Insulation Boards are high-density, extruded polystyrene sheets sized 1200x600mm with 10mm thickness, designed for underfloor heating and insulation. Featuring a compressive strength of 300 kPa and thermal conductivity of just 0.029 W/mK, they provide superior heat retention and structural stability. Water-resistant and recyclable, these boards reduce energy consumption while protecting against cold, damp, and mold, making them an eco-conscious choice for modern 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Insulation
*by F***D on 30 December 2022*

Used these to add insulation to the inside of an asbestos roof on my duck enclosure.The old roof was prone to condensation below 7°c so added these panels with a 5cm air gap between them and the roof then stuck Mylar sheets to the underside as a vapour barrier.The result was a +3°c inside temperature. Raising it from +2°c v outside to an average of +5°c.The dew point of the ceiling has changed dramatically and even in sub zero temperatures outside there is only a fine mist of condensation on the Mylar. Anything above zero and there is zero condensation.Boards were very easy to cut to size where needed, mainly scoring and snapping with a Stanley knife or where slightly more awkward shapes were needed I used a hacksaw.I sat them on screws fastened into the rafters so didn’t actually fix them but I would imagine they could be screwed carefully to a wooden surface or possibly glued or otherwise stuck to a surface as long as you used an adhesive that doesn’t damage the material.

### ⭐⭐⭐⭐⭐ Easy to cut
*by J***  on 26 May 2025*

Easy to cut and install used to insulate pond walls before liner installation

### ⭐⭐⭐⭐ Arrived damaged
*by P***N on 23 January 2025*

Arrived with damaged packaging to one edge, funnily enough, it's on a protected side, not the unprotected ends, I'd suggest better protection for transit, oh, and it was delivered to No.15, not number 11! Apart from that, it looks perfect for the job in hand, which is to insulate the walls in a built in wardrobe, to stop condensation mould. I can get around the slight damage when cutting to fit, which I'm sure I'll have to. The sheets are larger than I expected, even though it does give dimensions, so will cover areas pretty quickly. The blue will stand out a bit in the wardrobe, so I may paint it in the future. I've treated the walls twice, I'm waiting for the mould block paint, coming tomorrow, then the glue on Tuesday, I'll report back once the job is done. It looks good value for money, it's thicker than foil, should insulate better, should save on heating, protect clothes and cut easily.UpdateIt cuts really easy with a craft knife and straight edge. It's stuck really well with a water based adhesive, fits really flat to the wall. So I can't really fault this product. Warning, make sure that you buy enough, I'm a sheet short I think, although I may be able to patch an inconspicuous part with the odds and sods of offcuts, which unfortunately there's not a lot of, as you can only order a minimum of 10 sheets!
