ThermoShell - Solid Wall Insulation

Tackling the problem of solid wall insulation, ThermoShell External Wall Insulation offers solutions for upgrading the thermal performance of existing solid walls.

Many older properties have external walls that are either unsuitable for cavity wall insulation (often because the cavity is too small) or have no cavity to insulate (solid walls). The so called "hard to treat" walls still require insulating to reduce heat loss, and the ThermoShell system provides the solution.
