INCA is the Insulated Render & Cladding Association, representing system designers, specialist installers and key component suppliers to the external wall insulation industry.

All system designers offer BBA or BRE tested systems, proven in UK climatic conditions. Vetted installers have at least two years' experience in applying insulated render and cladding systems (except Provisional and Small Works members).

INCA's remit is to represent its members' interests by upholding the industry's reputation in:

• providing information and impartial advice on proven insulated render and cladding systems;
• promoting its use, concept and advantages for both refurbishment and new build;
• promoting vetted qualified installers;
• representing the industry when liaising with government, local authorities and other bodies;
• the promotion of quality through the development of uniform technical and professional standards and codes of practice.
