ACS A-Tray™ A1 Non Combustible Cavity Tray

A stainless steel cavity tray made from non-combustible material. This satisfies the latest regulations regarding fire safety and overcomes the problems that alternative products manufactured from combustible material pose.

The system is produced in-house from stainless steel sheet and provides a barrier to aid the passage of water from the internal structure/ cavity of the building to the exterior leaf.

Composed of two components:

• GT2 – This is a single sloping planar metal sheet which acts to dissipate moisture away from the inner leaf of the cavity wall. Its shape ensures water flows from the cavity towards the horizontal GT1 component embedded in the outer leaf of masonry. To aid the stability of the product, the upstand section is fixed to the internal leaf.
• GT1 – This is a single planar horizontal metal sheet with an angled upstand to the rear embedded into fresh mortar of the external masonry. This section collects water from the above mentioned GT2 section and drains it through the weep holes in the external masonry. The upward lip which is placed in the cavity space serves to prevent moisture from returning into the cavity.
