Wetherby secures BBA certification for façade system ..

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.

With the added assurance of BBA certification, 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.
