Spacetherm® Wallboard mitigates thermal bridging for Grade II building

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, while still providing a high performing thermal conductivity of only 0.015 W/mK.

Engineered for unsurpassed thermal performance in space-critical applications, Spacetherm offers exceptional thermal conductivity, plus breathability allied to hydrophobic characteristics. Spacetherm Blanket is an ideal choice for timber or steel frame structures and on request can be cut to a variety of widths and sizes to suit different applications. In addition, it can also be bonded to a wide range of boards and substrates. Its flexibility and ease of use, combined with exceptional thermal performance qualities, which can be retained for up to 50 years, make it a preferred choice for many architects and specifiers.
