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.
Reaction to Fire: Classified 'A2-s1, d0' to EN 13501-1
Thermal conductivity for Stonewool Core: λ90/90 = 0.034 W/m.K (EN 12667)

Chemical | The base stone wool is chemically inert. An aqueous extract of the rock wool is neutral (pH7) or slightly alkaline. Resistant to most acids and weak alkaline solutions. |
Biological | Vermin and rot proof and does not encourage the growth of fungi, moulds or bacteria. |
Effect of water | Product assembly provides suitable damp proofing in accordance with codes of practice for masonry constructions. The stonewool core is non-hygroscopic and unaffected by humid atmosphere. |
Compatibility | Protect from mortar snots during installation. |
Maintenance | No maintenance required unless disturbed. |
Handling | Easy to handle but should be treated with due care to ensure material integrity and shape are maintained. See Safety Data Sheet 7.1. |
