Lightweight yet high-density, these water-resistant boards prevent damp and cold penetration while offering long-lasting, stable performance. Made from fully recyclable materials, they provide an eco-conscious, cost-effective solution for insulating concrete floors, lofts, walls, and wet rooms. ## 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 energy This 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 damp CosySpace 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) ## 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 | B07HPF6N6C | | Best Sellers Rank | 621,735 in DIY & Tools (See Top 100 in DIY & Tools) 405 in Panel Insulation | | Brand | Cosyspace | | Coverage | 10.04 m2 | | Customer Reviews | 4.6 4.6 out of 5 stars (18) 4.6 out of 5 stars | | Item Dimensions L X W | 60L x 60W centimetres | | Manufacturer | CosySpace | | Material | Polystyrene | ## Product Details - **Brand:** Cosyspace - **Manufacturer:** CosySpace - **Material:** Polystyrene - **Product dimensions:** 60L x 60W centimetres ## Images ![XPS Boards Floor Underlay Thermal Insulation Underfloor Heating 600 x 600mm x 6mm Sheets - 1.86m2 to 18.60m2 - Image 1](https://m.media-amazon.com/images/I/51ZRy9ZNEUL.jpg) ![XPS Boards Floor Underlay Thermal Insulation Underfloor Heating 600 x 600mm x 6mm Sheets - 1.86m2 to 18.60m2 - Image 2](https://m.media-amazon.com/images/I/61wZ862U10L.jpg) ![XPS Boards Floor Underlay Thermal Insulation Underfloor Heating 600 x 600mm x 6mm Sheets - 1.86m2 to 18.60m2 - Image 3](https://m.media-amazon.com/images/I/61eHRnWGnKL.jpg) ![XPS Boards Floor Underlay Thermal Insulation Underfloor Heating 600 x 600mm x 6mm Sheets - 1.86m2 to 18.60m2 - Image 4](https://m.media-amazon.com/images/I/61mKb4tgCLL.jpg) ![XPS Boards Floor Underlay Thermal Insulation Underfloor Heating 600 x 600mm x 6mm Sheets - 1.86m2 to 18.60m2 - Image 5](https://m.media-amazon.com/images/I/61-6IGv8cVL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for under floor heating *by on Reviewed in the United Kingdom 22 April 2021* - 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. ### ⭐⭐⭐⭐ Did the job... *by on Reviewed in the United Kingdom 2 May 2019* ....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... ## Frequently Bought Together - XPS Boards Floor Underlay Thermal Insulation Underfloor Heating 600 x 600mm x 6mm Sheets - 1.86m2 to 18.60m2 - 220 Pieces Easy Fix Washers, 35mm Diameter Galvanised Steel Fixing Washers for Insulation Thermoboard Backer Boards (220) - 35mm Stainless Steel Washers, Easy Fix Washers, Tile Backer Board Washers, Diameter Galvanised Steel Fixing Washers for Gypsum Board Extruded Plate Insulation Thermoboard Backer Boards(50-PackοΌ‰ --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/88684237-xps-boards-floor-underlay-thermal-insulation-underfloor-heating-600-x](https://www.desertcart.com.br/products/88684237-xps-boards-floor-underlay-thermal-insulation-underfloor-heating-600-x) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-25*
