Why Join 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 key component suppliers throughout the UK. But why join INCA?

About INCA

INCA, the Insulated Render and Cladding Association, was formed back in 1982 to represent a then relatively new external wall insulation industry in the UK.

Back then, with EWI being such a new concept, much of the focus was on getting the system recognised, accepted and established within the UK construction industry.

As the EWI industry has expanded and evolved so too has the role of INCA. Today it is recognised by Government as the national trade association for the external wall insulation industry in the UK and whilst it is still very much focussed on promoting the benefits of the systems and finishes, it’s now also about driving best practice, quality assurance and influencing government policy and decisions which impact the industry as a whole and hence benefit the membership.

The current INCA mission says it all: To represent members of the External Wall Insulation industry through technical excellence, effective collaboration, strong marketing, communication and member benefits.

Who INCA Represent And How We Work

As a body INCA represents all the major EWI system designers in the UK along with a nationwide network of specialist installers and all the key component suppliers to the external wall insulation (EWI) industry.

Collectively the INCA membership are delivering high quality new build and refurbishment projects in both the residential and non-residential sectors across the UK. It is the first point of contact for Government and other key stakeholders and has active dialogue with all relevant governing departments and organisations including: BEIS, CLC, BEEF, EEIG, BUILDUK, CITB, SWIGA, Trustmark amongst others.

INCA Awards

There are various member events, meetings and conferences held each year. Of these the highlight of the calendar has to be the annual INCA Awards where external wall insulation excellence is recognised and rewarded and the very best in EWI is showcased for all to see.

Award nominations are free and open to all members with categories representing all sectors of the industry. Judging is by an independent panel of industry experts and winners are announced at a glittering “black tie” awards ceremony. You can Read More About THe INCA Awards Here >.

INCA – The Future

INCA fully supports the Governments commitment to Net Zero carbon emissions by 2050 and EWI has a hugely important part to play in this drive. The simple fact that domestic dwellings alone account for around 18% of carbon emissions demonstrates just how important EWI is and will continue to be in both the retrofit and new build markets.

INCA is therefore committed to continue to provide its members with the guidance and support they need and to help them set the benchmark for years to come by delivering highest quality installs of energy efficient, visually stunning and technically excellent projects.
