C A S E S T U D Y

Location: Imperial War Museum, London Fabrication Partner: The Proctor Group

Provide ceiling insulation for Barrel Vault area of Imperial War Museum in London. This area was overheating in the summer and very cold in the winter.Improve u-value to below 0.2W/m2K, while not reducing the floor to ceiling height.

The Proctor Group installed 20 mm of its Spacetherm blanket insulation on the ceiling. Spacetherm is a composite of Spaceloft® insulation and fibrous matting. It has a thermal conductivity of only 0.013W/mk, enabling high thermal performance in a thin, flexible blanket.

Spacetherm achieved a u-value of 0.18W/m2K, which exceeded the specification.Spacetherm’s 20 mm thickness barely reduced the floor to ceiling height.
