Alex Woodcraft, Managing Director of Ecoalex explains: “The apartment spreads over two floors and the front wall of the solid wall construction loses a large proportion of the heat. The roof area was insulated with layers of insulation and insulated plasterboard. The solid wall construction and design of the property meant that space for internal insulation was limited. We chose to apply Spacetherm WL (Wall Liner), from the A. Proctor Group, a high-performance laminate specifically designed to be adhered to the internal surfaces of existing solid walls without the need for mechanical fixings. At just 13mm thick, and given the limited wall space, the use of Spacetherm WL was ideal.”

Spacetherm WL consists of Spacetherm aerogel insulation blanket bonded to 3mm Magnesium Oxide Board, for use in applications where improved thermal performance is required with limited space. Spacetherm WL can be used with a variety of decorative finishes such as paint, wallpaper and tiles.

“The Spacetherm product was really easy and quick to apply,” comments Alex, “ the boards were fully installed and finished with a lime plaster skim in just two days. Spacetherm is an ideal solution for improving the thermal performance in space-critical applications, like the apartment at Quill Lane, and combined with its excellent breathability was also able to satisfy our requirement to ensure an improvement in air quality throughout.”

Typically, a solid wall will have a U value of around 2.1 W/m2K. Following the application of Spacetherm WL, this can be reduced to around 0.8 W/m2K, dependent on the wall structure.
