BBA Agrément Certificate
Certificate type
Siderise Cavity Tray, classified A2-s1, d0 to EN 13501-1. It is composed of aluminium facings and stone wool core providing a factory-engineered, pre-formed, and ready-to-fit cavity tray solution.
Application
Siderise CT Cavity Tray has been specially developed to meet the new requirements of Approved Document B for relevant buildings, where the use of traditional combustible cavity trays is no longer permitted above 18m in steel-framed structures (SFS).
Reaction to Fire
Siderise CT Cavity Tray has a ‘Reaction to Fire’ classification of ‘A2-s1, d0' to EN 13501-1 (Classification report available on request) and is therefore compliant for use with steel-framed structures (SFS) in relevant buildings above 18m.
Damp Proofing
As with traditional cavity trays, Siderise CT Cavity Tray provides an essential damp proof course (DPC) that crosses the cavity of a masonry wall to direct water out of the external face of the wall and to prevent dampness from permeating the internal skin of a wall.
Physical Properties
The Siderise CT Cavity Tray has a running length of 1m with a 50mm overlap joint. It is manufactured to triangular sections with a height of 150mm, an additional 50mm ‘top flange’ to the back wall and a 105mm ‘bottom flange’ at the base. The width is then manufactured to suit the cavity size with product made available in 5mm increments. A typical cavity width accommodated for the product is between 100mm to 350mm (for other cavities please contact Technical Services). Drainage is facilitated via weep holes as normal.
Description
Siderise CT Cavity Tray design features include dual aluminium skins to produce a secondary defence against moisture ingress. The aluminium faces of the Cavity Tray are robust and durable to cope with site installation whilst ensuring that the water permeability is not compromised. The same unique formulation of stonewool is used in the central core of the Cavity Tray as is used for all Siderise® fire barriers to maintain continuity of performance. Refer to the manufacturers SFS or Blockwork Installation Instructions and Standard Details for the Cavity Tray product sequencing. Please also see manufacturers product page for all resources.
