Spacetherm the solution for hard to treat walls. When Matt Mullaly MRICS were looking for a thermal solution to the upgrade of the solid walls at the historic custom house at Gorran Head, Cornwall, they approached the A. Proctor Group.

As a result, Spacetherm® F was specified to improve the thermal performance of the walls whilst minimising impact to the room sizes. Spacetherm® F is one of a range of products from The A. Proctor Group which utilise the most thermally efficient of all insulants, aerogel. The insulation is a composite of fibrous matting and aerogels. It is a low density solid derived from a gel, in which the liquid component has been replaced by gas, using a process known as supercritical drying. This results in a material which has remarkable insulation properties.

Spacetherm® panels are designed to insulate hard to treat, solid walls internally, and due to the extremely low thermal conductivity of only 0.015W/mK, the panels are very thin, and can be fixed directly to the wall, thereby not dramatically encroaching on precious roomspace.

Spacetherm® F can be fixed using stainless steel wood screws to timber straps with a DPC backing, also available from A. Proctor Group. Spacetherm® F utilises Fermacell as the panel, providing a robust board which is ready for decoration.
