Keyfix, part of the Keystone Group of companies, specialises in the development of non-combustible masonry accessories. Synergising 30+ years of Keystone experience in structural steel including Lintels and Masonry support, Keyfix provides the complete non-combustible solution for external masonry facades.

Keyfix is setting new standards in the delivery of non-combustible cavity systems for projects requiring Document B compliance. In buildings utilising steel frame systems in the external cavity, the innovative non-combustible A1 fire rated Cavity Tray System is a practical solution to provide Damp Proof Course (DPC) protection over lintels, masonry supports, soffit systems and other elements in the cavity such as fire barriers.

Designed for rapid build, the Keyfix Non-combustible Cavity Tray is a ‘Fix + Forget’ self-supporting, single piece tray that clicks together for fast, easy, single handed installation. No additional fixings, sealants or fabrication are required so installation of the trays will not impede the speed of brick laying when compared to any traditional DPC.

Other products in the Keyfix Non-combustible Solutions range include:

- Non-combustible Cavity Tray Lintel

- Non-combustible Retaining Disc

- Non-combustible Weep vents

- Non-combustible DPC
