Solid Wall Insulation

Why Solid Wall Insulation?

Solid Wall Insulation can be applied either internally (IWI) or more commonly externally (EWI). Planning permission and specification design often dictates the process chosen.

External wall insulation is a panelling of insulation board fixed to the building’s surface. A series of meshes, renders and finishing coats are then applied to complete the system.

A new attractive facade, which is weatherproof and highly insulated, provides the resident with a warmer home and lower energy bills.

Internal Wall Insulation is a simple build-up of insulation board, plasterboard, render and de-signed finish to match internal decoration.

Solid Wall Insulation has revolutionised the way buildings old and new, residential or commercial can be built or refurbished. U-values can easily be achieved that meet current and proposed Part L building regulations, vastly improving the thermal and condensation characteristics of the living or working environment.
