Swift solutions for EWI

External Wall Insulation (EWI) is the application of an insulation layer to the outside wall of a building in order to improve the building’s energy efficiency.

By minimising heat loss in cold weather and heat gain in warm weather, EWI creates a more comfortable living environment and reduces heating costs. The insulant is typically expanded polystyrene or mineral fibre of varying thickness, typically finished with a render, brick / stone effect finish or a cladding.

AfS have two products designed to sit within EWI and provide comfortable nesting spaces for swifts and other small birds.
