The ongoing issue of hard-to-treat walls in the UK can be overcome using Spacetherm - an ultra-thin insulation for thermal upgrades saving valuable space without altering the exterior fabric of the building.

One project that benefited from this ultra-thin insulation was at 20 Follet Street, Tower Hamlets, London. Using innovative technologies the solid wall Victorian House in a Conservation area was upgraded with an 80% carbon emission reduction. The historic nature and context of the house, its position fronting directly onto the street and the proximity of adjacent buildings have played a key part in the selection of material and renewable technologies. This retrofit solution enables the resident to remain in occupation of the house.

Whole house modelling was undertaken using SAP in conjunction with extended SAP worksheet. AutoCAD produced plans and elevations were used to assist with visualisation and detailed design.

The A. Proctor Group Ltd supplied Spacetherm P (Spacetherm insulation bonded to Plasterboard) to this project where it was installed in the exposed walls to give a U-value of 0.23 W/m2K. Spacetherm can be supplied on its own and cut to size or laminated to a number of facings to suit your individual requirements. Its remarkable performance is achieved through the use of flexible aerogel blankets. The insulation used in Spacetherm is material derived from silica gel.
