Saint-Gobain Brands Secure Multiple wins at 2025 INCA Awards

Two of the UK’s leading external wall insulation (EWI) brands – K Systems and Weber, which are both part of Saint-Gobain Exterior Solutions – have secured five collective wins in the 2025 INCA Awards.

At the annual awards ceremony at The Queens Hotel in Leeds, K Systems (a brand previously from Kilwaughter Minerals) was successful in three categories – Refurbishment: Low Rise - Render/Traditional Finish, Refurbishment: Single Storey - Render/Traditional Finish, and Refurbishment: Non-Residential – Render/Traditional Finish.

Weber, meanwhile, won the New Build: Render/Traditional Finish accolade as well as winning the Judges’ Choice award in the Architectural Design category.

The Insulated Render and Cladding Association (INCA) represents the UK’s external wall insulation industry, championing best practice in design, manufacture, supply, and installation. Its annual awards celebrate outstanding achievements across the sector and are recognised as a benchmark of quality and innovation.

Caroline Rowley, Business Development Director at Saint-Gobain Exterior Solutions, commented:

“K Systems and Weber are two premium brands with a proven pedigree, and the multiple INCA successes enjoyed by Saint-Gobain Exterior Solutions further highlights the versatility and breadth of expertise within the group.

“We are delighted to be able to offer such a broad portfolio of solutions to the market and to have that INCA recognition – an industry accolade that is held in such high esteem – is a fantastic endorsement of the work our teams are proud to carry out every day.

“We look forward to building on that success for customers in the future as we continue to deliver design flexibility, sustainable homes and a trusted lasting performance for communities across the UK.”

K Systems was rewarded for successful project completions at St Giles Community Centre in Lincoln (Non-Residential - Render / Traditional Finish), Cheviot Court in North Ayrshire (Refurbishment: Single Storey - Render / Traditional Finish), and the Welwyn and Hatfield Social Housing Decarbonisation Fund in Welwyn and Hatfield.

Weber’s work on the Upper Court Care Facility in Surrey secured the New Build: Render/Traditional Finish victory, with its success in the Judges’ Choice Architectural Design category earned for its work on a Contemporary New Build in Nottingham which the judges described as “a beautifully designed building and an expertly-installed system”.

Kilwaughter Minerals became part of the multi-national Saint-Gobain group in December 2024. In March 2025, Kilwaughter Minerals and Weber were brought together as Saint-Gobain Exterior Solutions, with each company’s market-facing brands continuing to operate and trade as normal.

Saint-Gobain is a global leader in the design and manufacture of solutions for the construction industry and employs 160,000 people across 76 countries worldwide.
