Wetherby Wall Systems Launches the UK’s First Fire-Tested Below DPC Insulation System

Wetherby Wall Systems, part of the ROCKWOOL Group, is delighted to announce the launch of SOQEL A2, a fully compliant, impact-resistant, and moisture-protected External Wall Insulation (EWI) system designed for below damp-proof course (DPC) applications.

Launched on 17th March, SOQEL A2 sets a new benchmark for fire safety and durability in external wall insulation. It’s the first fully fire-tested system for below DPC applications, meeting the latest A2-s1,d0 fire classification required for materials in buildings over 11 meters. This ensures compliance with the UK Building Regulations and provides a solid solution for the construction industry.

With UK building regulations now requiring that materials used in buildings over 11 meters must meet a minimum A2-s1,d0 fire rating, SOQEL A2 offers architects, contractors and specifiers a reliable solution in line with these regulations. Designed for use in below DPC areas, as well as balconies, walkways and plant rooms, the system improves fire resistance, impact protection and long-term moisture durability. Unlike traditional solutions, such as bitumen paint, SOQEL A2 delivers a more effective and resilient alternative.

Game-changing system

This game-changing system integrates Coverrock x-2 pre-coated insulation, which ensures a strong and durable bond for coatings while protecting the A1-rated Stone Wool core during installation. Paired with Heck K+A SL coating and Heck CER Mesh, it also provides superior impact and moisture resistance, withstanding harsh weather and high foot traffic in exposed areas like balconies and plant rooms. 

SOQEL A2 incorporates Heck 4S Silicone Render, ensuring a seamless finish that matches the overall façade system. Unlike traditional below DPC treatments, which may disrupt the building’s aesthetics, it offers a modern, integrated look while maintaining full regulatory compliance. 

Joe Ragdale, Technical Director at Wetherby Wall Systems, comments: “We have worked alongside our ROCKWOOL Group sister company, HECK in Germany to launch this innovative system into the UK market. We are delighted to introduce SOQEL A2, the first system of its kind for below DPC and base areas.”

“This solution provides architects and contractors working on remediation projects with a compliant, durable, and efficient way to enhance building safety while ensuring a seamless finish alongside insulated façade systems.”
