External Wall Insulation Systems

Around 30% of the energy used to heat a typical building is lost through the external walls.

The StoTherm range of external wall insulation systems significantly reduces this energy loss by wrapping the building in a thermally resistant envelope, maximising internal space and maintaining comfortable internal temperatures all year round. And you don't need to compromise on aesthetics: Each system can be finished in a wide range of renders and architectural elements.
