We are proud to announce that the Infinity Tray has now achieved full BBA certification (British Board of Agreement), marking a significant milestone in our continued commitment to compliance, product performance, and quality within the UK construction sector. This independent approval reinforces Infinity Tray as a trusted, regulation-ready solution for modern cavity wall construction.
BBA approval is widely recognised as one of the most respected third-party certifications in the construction industry. For architects, specifiers, contractors, and building control professionals, it represents independent verification that a product has been rigorously assessed for durability, safety, and fitness for purpose under real UK site conditions. With increasing scrutiny around building safety, external wall compliance, and fire performance, this certification provides vital assurance that Infinity Tray is fully suitable for use on regulated construction projects.
Designed for Modern Construction and Evolving Building Regulations
Manufactured in the UK using A1 fire-rated stainless steel and fully non-combustible materials, the cavity tray system delivers robust moisture management while supporting modern façade fire strategies and long-term structural integrity.
In recent years, updates to Approved Document B and Regulation 7 of the Building Regulations have placed strict limitations on the use of combustible materials within external wall systems, particularly on residential and high-risk buildings over 18 metres, soon reducing to 11 metres. Infinity Tray directly supports compliance with these requirements by offering a fully non-combustible cavity tray solution manufactured entirely from stainless steel.
This makes Infinity Tray particularly suitable for use in high rise residential, commercial, healthcare, education, and mixed-use developments where fire safety, compliance, and long-term performance are critical.
Key Technical Features of the Infinity Cavity Tray System
Infinity Tray is supplied as a full, integrated, non-combustible cavity tray system designed to accommodate a wide range of construction details and site conditions. Key considerations engineered into the system include:
- A full suite of non-combustible cavity tray components, including over door and window lintels, window and door brick reveal stop ends, doorsills, and associated accessories
- Suitability for modern methods of construction and contemporary façade detailing
- Long-term resistance to corrosion and environmental exposure
- Excellent heat resistance and fire performance
- Manufactured in controlled UK production environments
- Reduced maintenance risk over the lifecycle of the building
- Suitable for fusion welding where fabrication flexibility is required
- Independent verification of fitness for purpose
- Assurance of long-term durability in UK environmental conditions
This is particularly important in today’s construction environment, where compliance risk, programme pressure, and inspection scrutiny continue to increase across all project types.
Non-Combustible Performance and Fire Safety at the Core
Fire safety performance is no longer optional in external wall design – it is fundamental. Infinity Tray is manufactured using A1 fire-rated stainless steel, classified as non-combustible under European standards. This ensures:
- No contribution to fire load within the cavity
- Compliance with government prohibitions on combustible materials
- Support for external wall fire strategies
- Improved safety performance across the building envelope
Where cavity trays interface with other façade components, Infinity Tray supports the use of compatible non-combustible accessories, including A1-rated cavity weep vents and approved sealing systems, further strengthening overall façade fire compliance.
Specification & Compliance
We understand how critical it is to balance performance, compliance, and build efficiency on live projects. With rising regulatory pressure and increasing programme demands, having a fully certified, non-combustible cavity tray system in place helps de-risk both design and construction phases.
To support efficient project delivery, we offer comprehensive Take-Off & Measures, supplying full masonry or material-specific take-offs covering ties, fixings, fire barriers, cavity trays, insulation, bricks, and blocks.
