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' 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' 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.

Siderise 'CT' is a lightweight solution that is simple to install and provides a durable solution to the problem of damp penetration below the roofline of a masonry structure. It is easy to handle and can be installed on-site without any specialist equipment.


Physical Properties

The product 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. 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's design features include dual aluminium skins to produce a secondary defence against moisture ingress. The aluminium faces 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 as is used for all Siderise® fire barriers to maintain continuity of performance. Refer to the Installation Instructions and Standard Details for product sequencing.
