Mapei is proud to announce that it is officially registered with the IAA (Installation Assurance Authority) as an approved External Wall Insulation (EWI) system designer. The accreditation highlights Mapei’s continued commitment to delivering high-performance and independently-verified solutions that meet the highest standards in the industry.

The IAA ‘is the technical authority and industry body that provides a quality assurance framework under a single compliance platform. This gives homeowners, key stakeholders and funders the confidence that insulation work is carried out to the highest standards and subject to a level of rigor and surveillance which helps ensure it is done ‘Right First Time’.

“For our customers, this registration represents more than a certification; it’s a promise of added value. IAA-backed systems benefit from robust guarantees, third-party oversight and alignment with government-backed energy efficiency initiatives. Whether you’re a contractor, specifier or local authority, partnering with Mapei now means greater peace of mind, compliance with the latest industry requirements and support from one of the most trusted names in the sector,” commented Ahmed Sobhy, Mapei Category Manager – EWI and Coatings.

Mapei BBA-accredited EWI thermal insulation systems incorporate EPS insulated panels or Mineral Wool applied on various substrates covering most sectors’ requirements. They form part of Mapei’s full system product portfolio which offers a fully integrated building envelope solution that spans from the foundation to the roof.
