Non-combustible cavity trays
The new range of Non-Combustible Stainless Steel Cavity Trays provides an innovative solution which is fully compliant with the requirements of Document B in regards to fire safety in the external cavities of buildings over 18m high with a steel frame inner leaf.
Designers and contractors alike are faced with the challenge of finding effective non-combustible solutions for cavity trays to replace the systems they have traditionally used to provide watertight protection above elements which cross the cavity such as masonry supports, soffit systems, fire barriers etc.
Uniquely, we can offer a range which includes non-combustible solutions for within the cavity, and also a structural lintel with combined cavity tray providing a non-combustible solution for openings in the external leaf.
INCLUDED IN THE RANGE
The Type 1 NCCT is a highly practical solution to the challenge of non-combustible cavity detailing. The ease of installation in the outer leaf combines with the advantages of its self-supporting structure. These features allow the profiling of insulation and the positioning of the overlap on the cavity facing membrane to be completed independently once the tray is securely built into the brickwork. The base of each tray features a patented indented surface to protect against a slip plane.
Interlocking Trays
The patented design enables the trays to interlock and create a watertight joint which includes an integral weep vent. This unique detail also provides brickwork joint width adjustability of between 7-13mm. No tapes or sealants are required.
Non-Combustible weep vent
To comply with building regulations, non-combustible stainless steel weep vents are placed at 450mm centres on the 4 and 6 brick trays.
Component Range
The range of one, two, four and six brick trays combine with handed internal and external 90°corner trays to accommodate various build conditions and eliminate the need to fabricate trays on-site. The Type 1 tray is suitable for cavity widths between 100mm-225mm.
NCCT1 – One piece, self supporting non-combustible stainless steel cavity tray
NCCT2 – Two-piece non combustible stainless steel cavity tray
Corner Trays Type 1 NCCT-1
90-degree pre-formed internal and external corner trays facilitate the seamless installation around the building without the need to cut or fabricate onsite.
Corner Trays Type 2 – NCCT-2
90-degree pre-formed internal and external corner trays Type 2 facilitate the seamless installation around the building without the need to cut or fabricate onsite.
