The A. Proctor Group of Blairgowrie, Scotland, has provided an individual solution for upgrading the thermal insulation of old modular classrooms at Methven Primary School using Spacetherm.

The primary school in Perthshire had old modular classrooms for teaching, which although previously insulated, were not up to current standards. The nature of the modular construction also meant there was a cold bridge where the units were bolted together.

Perth & Kinross Council specified Spacetherm, as its unique thermal performance was ideal, as space restrictions within the classrooms was critical. 6mm Spacetherm F (Fermacell) was used on the walls with 6mm Spacetherm Plywood being installed onto the floors.

Spacetherm is a composite of fibrous matting and aerogels, the newest and most thermally efficient of all insulants. Aerogel is a low density solid derived from a gel in which the liquid component has been replaced by gas using a process know as supercritical drying. This results in a material which has remarkable insulation properties of 0.013W/mK.

The design of the installation of the Spacetherm also meant that the classrooms could be easily dismantled and moved at a later date, without disrupting the integrity of the internal finish and insulation.
