Spacetherm Wallboard has been supplied by the A. Proctor Group to mitigate thermal bridging for the historic Electricity House building in Bristol, recently converted by Crest Nicolson into a series of luxury flats ranging from £230,000 to £530,000. The renowned architect, Sir Giles Gilbert Scott, the creator of the iconic Battersea Power Station, designed the original Grade II listed building.
Used in this instance as a Window Reveal Board, Spacetherm Wallboard was developed to prevent thermal bridging through a component or element of a structure. Spacetherm Wallboard is a high performance laminate, which consists of Spacetherm Aerogel insulation blanket bonded to plasterboard, and is ideal for use in applications where low U-values are required, and space is at a premium.
Planning requirements stipulated that the original window opening aperture sizes had to be maintained, and to alleviate thermal bridging on the existing window reveals, a thin insulation solution was crucial. Spacetherm offers superior thermal performance, which enabled the contractor to insulate the existing window reveals with just 17.5mm overall thickness, whilst still providing a high performing thermal conductivity of only 0.015 W/mK.
