Grayson Building Products has welcomed the publication of the Masonry Association of Great Britain’s latest Technical Note, “The Importance of Compression in Cavity Fire Barriers.”
The guidance provides valuable clarification for designers, specifiers and contractors by reinforcing a principle that has always been fundamental to the design and installation of FireBlox™ Plus—that controlled compression is essential to maintaining the long-term fire performance of a non-ventilated cavity barrier.
The independent guidance highlights the importance of allowing for factors such as construction tolerances, drying shrinkage, differential settlement, structural loading and building movement when specifying and installing cavity fire barriers. These are all real-world considerations that can affect cavity dimensions throughout a building’s life and must be taken into account to ensure continued fire protection.
At Grayson, we fully support these findings.
FireBlox™ Plus has always been designed and installed with controlled compression in mind. Our technical guidance has consistently recognised that buildings are dynamic structures and that cavity barriers must be capable of maintaining their integrity as construction materials settle, dry and move over time.
The Masonry Association’s latest Technical Note reinforces this engineering-led approach and provides further confidence for architects, fire engineers, principal designers and contractors seeking robust, evidence-based passive fire protection solutions.
As the construction industry continues to raise standards following the Building Safety Act, independent technical guidance has never been more important. Grayson is proud that FireBlox™ Plus has long embodied the principles now being reinforced by the UK’s leading masonry trade body.
FireBlox™ Plus combines proven installation methodology with extensive independent fire testing and third-party certification, giving specifiers confidence that they are selecting a cavity barrier designed to perform not only on the day it is installed, but throughout the life of the building.
We commend the Masonry Association of Great Britain for publishing this important guidance and welcome the continued focus on improving best practice across the construction industry. By working together to promote technically robust, independently supported solutions, we can continue to improve building safety and deliver greater confidence for everyone involved in the design, construction and occupation of our buildings.
