INCA - About The Organisation

About INCA: The Insulated Render and Cladding Association (INCA) is the recognised trade association for the External Wall Insulation (EWI) industry, representing the major system designers, a nationwide network of specialist installers and the key component suppliers.

INCA is at the forefront of transforming the energy efficiency of homes and businesses in the UK – the mission: to represent members of the External Wall Insulation industry through technical excellence, effective collaboration, strong marketing and communication and member benefits.

What Is EWI (External Wall Insulation)?

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 much more comfortable living environment and reduces heating costs.

EWI is a composite system made up of three basic components: an insulant, a fixing, and a render or cladding. The insulant is secured to the wall using either special adhesives or purpose-made fixing screws/dowels. The final surface, which provides both the aesthetic and weatherproofing functions of the wall, is usually a coloured render but could also be a brick effect or other specialist finish. A range of EWI systems are available allowing the building owner to prioritise between cost and technical performance.
