Insulation and finish as one designed system
External wall insulation places an insulation layer on the outside of suitable walls before applying a reinforced basecoat and decorative finish. It can change both the thermal performance and appearance of a property, but it requires more detailed assessment than a straightforward render-only project.
Why manual review is essential
Wall construction, roof overhangs, window reveals, damp risks, services, ventilation and detailing all need consideration. For this reason the online estimator treats EWI as an allowance and Vale Render confirms the correct approach only after reviewing the property.
VAT and specification
VAT treatment and system specification can vary with the nature of the work and current rules. These are confirmed in the formal quotation rather than assumed from the provisional estimate.
