Wetherby secures BBA certification for Its A1-rated Brick Effect façade system

A major step forward in façade safety and compliance has been achieved with the announcement that the popular Brick Effect Render system from EWI provider Wetherby Wall Systems now carries full BBA (British Board of Agrément) certification and achieves an A1 fire rating to EN 13501-1 when installed with stone wool insulation.

This marks a significant upgrade to an already trusted system for the ROCKWOOL Group company. Brick Effect Render has long been favoured for its ability to deliver the traditional look of brickwork while offering faster installation, excellent durability, cost efficiency and greater design flexibility.

With the added assurance of BBA certification and the highest level of fire performance, it now sets a new benchmark for safe and compliant façade solutions.

“Our Brick Effect Render has always been popular for its traditional aesthetic. Now, specifiers and contractors can choose it with full confidence that it meets the highest fire safety and certification standards available in the UK,” said Joe Ragdale, Technical Director at Wetherby.

The system is applied in two layers, starting with a coloured mortar base followed by a complementary top coat. This top layer is carefully cut back to reveal a realistic brick finish that combines visual appeal with exceptional performance. When used with stone wool insulation, the system achieves an A1 classification for non-combustibility under European testing standards.

The BBA certification confirms that the Brick Effect Render system meets UK building regulations and performs consistently across key areas including impact resistance, thermal efficiency, weather protection and long-term durability. Wetherby also offers the option of an extended warranty, with a life expectancy of up to 60 years, providing added reassurance for clients seeking long-term performance.

Available in a wide range of realistic colours such as Bolton Red, Bronte Stone and Manchester Red, the system is suitable for full façades, feature panels or detailed architectural elements. It is widely used in both new build and refurbishment projects where visual appeal and technical performance are equally important.

Now with verified A1 fire safety and independent BBA certification, the Brick Effect Render system offers complete peace of mind for contractors, developers and specifiers working on projects where safety, compliance and design flexibility are essential.
