Advanced Protection for Every Build
We understand that effective party wall protection is critical in both masonry and timber frame construction. That’s why we’ve developed two industry-leading systems. One system tailored for masonry low-rise buildings, the other for timber frame structures, each offering comprehensive fire stopping and thermal performance you can trust.
Whether you’re working on a traditional masonry build or a modern timber frame project, ARC’s Party Wall Systems deliver fully tested, third-party certificated solutions that enhance safety, support energy efficiency, and help meet or exceed regulatory requirements.
One Goal, Two Tailored Systems

The ARC Masonry Party Wall System
is specifically designed for low-rise masonry construction, offering robust protection against fire spread through the party wall cavity while minimising heat loss at key junctions. With nine high-performance components that work together or individually, the system ensures seamless integration into any masonry project.

The ARC Timber Frame Party Wall System
delivers the same high standards for timber frame buildings; a fully tested, complete solution designed to prevent the spread of fire in hidden cavities whilst sealing vulnerable junctions to reduce thermal bypass and reduce energy bills. Fully tested and certified, it’s a complete solution that protects properties and the inhabitants within them.
Fire Safety and Energy Efficiency Built In
Both systems go beyond compliance – they’re about future-proofing your build. By targeting common details in the party wall cavity, each system not only prevents the unseen spread of fire but also significantly reduces uncontrolled heat loss, supporting greater sustainability and lowering heating bills for the end user.
Each system includes expertly engineered components which ensure full coverage from foundation to roofline.
