Masonry Support Systems and Fire Protection Cavity Barriers 

This new whitepaper aims to raise industry awareness of the interaction between masonry support systems and cavity barriers. Authored by our team of industry experts, it delves into the research we have carried out alongside leading cavity barrier suppliers and provides clarity for building professionals involved in the design and detailing of such systems.  

As building codes and safety regulations continue to evolve, the need for clear guidelines and best practice in masonry construction has never been more critical. We identified a need for greater understanding, and more robust data, regarding the often-complex interaction between cavity barriers and masonry support systems and have taken a collaborative approach with all the main cavity barrier suppliers in the market to address this.

Our latest white paper brings this work together, providing clarity for architects, engineers and contractors involved in façade design and detailing. Authored by our industry experts, it highlights typical build-ups, explains how key regulations apply, and shares insights from collaborative testing across multiple suppliers.


“Our goal with this white paper is to demystify the complexities surrounding masonry support systems and passive fire protection. By providing clear insights and practical solutions, we hope to support architects, engineers and contractors to make informed decisions that enhance both safety and structural performance. Our collaborative approach has strengthened the quality of available data and helped ensure that Ancon masonry support systems are thoroughly tested wherever they interact with cavity barriers.”
