Lightweight yet high-density, these water-resistant boards prevent damp and mold, ensuring long-lasting performance. Made from fully recyclable materials, they offer a sustainable, cost-effective solution ideal for concrete floors and various 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) ## 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 | B07HPD6FF2 | | Best Sellers Rank | 630,772 in DIY & Tools ( See Top 100 in DIY & Tools ) 419 in Panel Insulation | | Brand | Cosyspace | | Coverage | 8.55 m2 | | Customer Reviews | 4.6 4.6 out of 5 stars (18) | | Manufacturer | CosySpace | | Material | Polystyrene | ## Product Details - **Brand:** Cosyspace - **Manufacturer:** CosySpace - **Material:** Polystyrene ## 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/31yqw-YD4pL.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/51-GROV15TL.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/51yr2OO8eaL.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/51-WQXxVEiL.jpg) ## Available Options This product comes in different **Size** 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.sg/products/790228905-xps-boards-floor-underlay-thermal-insulation-underfloor-heating-600-x](https://www.desertcart.sg/products/790228905-xps-boards-floor-underlay-thermal-insulation-underfloor-heating-600-x) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-15*
