Foamglas insulation for Corpus Christi College

Foamglas was judged to be able to insulate the building and at the same time provide the compressive strength needed to support the roofing system.

Richard Keep, associate at Rick Mather Architects, said: 'Foamglas was installed with a single-ply membrane and a timber or stone roof deck on top of this.' Foamglas cellular glass insulation is available in a range of compressive strengths from 400kN to 1600kN per m2.

Keep added: 'As a practice we have used cellular glass insulation many times as it meets high-performance criteria but at the same time has very good eco-credentials, which is incredibly important to the ethos of our practice.' Manufactured from 68 per cent recycled glass and a small element of carbon, Foamglas cellular glass insulation is totally impervious to water, does not deteriorate with age and its thermal properties remain constant.

Its core is totally non-combustible (Euroclass A1) and it cannot contribute to a fire or give off toxic fumes.
