Spacetherm WL (Wall Liner) is a high performance laminate specifically designed to be fixed to internal surfaces of existing solid walls without the need for mechanical fixings. Spacetherm WL consists of 10mm Spacetherm aerogel insulation blanket bonded to 3mm Magnesium Board (MgO), for use in  applications where improved thermal performance is required with limited space. Spacetherm WL can achieve similar performance to traditional plasterboard laminates, but at a fraction of the thickness, allowing specifiers greater flexibility and higher performance for refurbishment projects.


Key Features


• Thin insulation system for hard to treat walls.
• Class leading performance.
• Minimum loss of room space.
• Constant long term thermal performance 50 years+.
• Non-hazardous material.
• Easy refurbishment
• No specialist trades required
• Allows wall to breathe



The Spacetherm WL system is suitable for a variety of finishes such as paint, wallpaper and tiles. Spacetherm WL should be bonded to a clean, bare and structurally sound base using Insta-Stik adhesive.
