Featuring a low thermal conductivity of 0.029 W/mK and a compressive strength of 300 kPa, these lightweight, recyclable boards excel in underfloor heating setups and damp-proofing. Their closed-cell structure ensures energy efficiency, durability against freeze-thaw cycles, and sound reduction, making them an eco-friendly, cost-effective solution 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. 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 ## Features - Best Used With An Underfloor Heating Kit On Concrete Flooring a Low Cost Proxy To Tile Backer Board - High Density, Light Weight And Low Cost Make This Foam Board Ideal In A Poorly Insulated Property - XPS Boards Are An Extruded Polystyrene Insulation Board Made Through A Plastic Extrusion Process - Widely Used In Walls And Loft Insulation, Underfloor Heating, Roof, Wet Room, And Non Moisture Areas - Stable Performance, Anti-ageing, Resistant To Compression, Water Resistant, Lightweight, Recyclable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5MRYTPC | | Best Sellers Rank | 188,885 in DIY & Tools ( See Top 100 in DIY & Tools ) 130 in Panel Insulation | | Brand | Cosyspace | | Country of Origin | United Kingdom | | Customer Reviews | 4.6 4.6 out of 5 stars (199) | | Included Components | No | | Item Dimensions L x W | 12L x 6W metres | | Item Thickness | 10 Millimetres | | Item Type Name | xps Insulation Board | | Manufacturer | CosySpace | | Material | Polystyrene | | Model Number | Cosysapce | | Number of Items | 1 | | Number of Packs | 18 | | Recommended Uses For Product | Thermal Insulation, Moisture Protection | ## Product Details - **Brand:** Cosyspace - **Item thickness:** 10 Millimetres - **Material:** Polystyrene - **Product dimensions:** 12L x 6W metres - **Recommended uses for product:** Thermal Insulation, Moisture Protection ## Images ![XPS Foam Insulation Boards 1200 x 600 x 10mm - Electric and Water Underfloor Heating Tile Laminate Underlay Thermal Extruded Polystyrene Insulation Sheets (18, 1200 x 600 x 6mm) - Image 1](https://m.media-amazon.com/images/I/41yReJd6ptL.jpg) ![XPS Foam Insulation Boards 1200 x 600 x 10mm - Electric and Water Underfloor Heating Tile Laminate Underlay Thermal Extruded Polystyrene Insulation Sheets (18, 1200 x 600 x 6mm) - Image 2](https://m.media-amazon.com/images/I/21uZkKthLyL.jpg) ![XPS Foam Insulation Boards 1200 x 600 x 10mm - Electric and Water Underfloor Heating Tile Laminate Underlay Thermal Extruded Polystyrene Insulation Sheets (18, 1200 x 600 x 6mm) - Image 3](https://m.media-amazon.com/images/I/31N65mGnk7L.jpg) ## Available Options This product comes in different **Size, Item Package Quantity** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/646247087-xps-foam-insulation-boards-1200-x-600-x-10mm-electric](https://www.desertcart.tn/products/646247087-xps-foam-insulation-boards-1200-x-600-x-10mm-electric) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-11*
