## 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 XPS insulation boards, also known as extruded polystyrene insulation boards, are a type of rigid foam board insulation that is commonly used in the construction industry. The boards are made from polystyrene resins and are produced by a process of extrusion, whereby melted polystyrene is forced through a die to form a rigid foam board. They have closed-cell structure that provides excellent thermal insulation and sound proofing properties, making them highly effective at reducing heat loss in buildings. They are also water-resistant, which makes them ideal for use in damp or humid places. XPS insulation boards are lightweight and easy to handle, making them simple to install in walls, roofs, floors, and other building components.

## Features

- Size : 600x600mm Available in 6mm 10mm 20mm & 30mm Thickness
- High R-Value: XPS foam has a high R-value, which measures its thermal resistance. Its closed-cell structure and low thermal conductivity make it an efficient insulator, helping to keep buildings warm in cold weather and cool in hot weather.
- Moisture Resistance: XPS foam is highly resistant to moisture and does not absorb water due to its closed-cell structure. This property makes it suitable for use in areas prone to moisture
- Durability: Cosyspace XPS is 300kpa this helps it withstand heavy loads and pressure without significant deformation, making it suitable for use in various construction applications.
- Widely Used In Walls And Loft Insulation, Underfloor Heating, Roof, Wet Room, Laminate Underlay, Tiling Underlay
- Soundproofing: XPS foam also offers soundproofing benefits by absorbing and reducing sound energy, making it a good choice for acoustic applications or to improve the acoustic performance of a room.
- Lightweight and Easy to Handle: XPS foam is relatively lightweight and easy to handle, making it convenient to work with during installation.
