Cavity Barriers in Masonry External Walls

Description

This CPD module explores the critical role of cavity barriers in ensuring fire safety within masonry external wall constructions. It highlights the importance of passive fire protection, focusing on barrier placement, location, and integration within complex masonry designs—including stepped and uneven brickwork.

Beyond fire performance, the session examines key design considerations such as drainage, moisture management, thermal and acoustic properties.

Attendees will gain insight into UK compliance pathways, including relevant regulations, statutory requirements, and the Building Safety Act. The CPD also underscores the value of third-party certification, with examples covering product performance, environmental credentials, and industry-recognised schemes.

Practical guidance is provided on detailing around masonry supports, projections, and congested areas, with an emphasis on best practice. The module concludes by reinforcing the importance of competence, accountability, and traceability throughout the design and construction process—supporting the Golden Thread of information through effective interface detailing, training, installer competency, site inspections, and record-keeping.
