INCA – The Membership

INCA, The Insulated Render and Cladding Association, is THE recognised trade association for the external wall insulation (EWI) market in the UK.

Whilst we work closely and collaboratively alongside other associations within the insulation industry – TrustMark, SWIGA, National Insulation Association (NIA), Installation Assurance Association (IAA) to name but a few, what sets INCA and its membership apart is that we are solely focussed on external wall insulation within this wider insulation market.

We also support all industry sectors – new build, refurbishment, domestic, non-domestic, high rise, low rise, off site, MMC, self-build etc and all size of projects too … any form / size of construction / renovation which involves external wall insulation.
