Non-combustible Cavity Tray System

Keyfix is setting new standards in the delivery of Non-combustible Cavity Tray Systems for projects requiring Document B compliance in buildings utilising steel frame systems in the external cavity. Our innovative non-combustible A1 fire rated Cavity Tray system is a practical and technically superior solution to provide DPC protection over lintels, masonry supports, soffit systems and other elements in the cavity such as fire barriers.

Classified A1 Fire Rated

Manufactured using only Class A1 Non-combustible Grade 304 austenitic stainless steel ensures a lifespan of 125+ years for the entire system. For coastal locations Grade 316 austenitic stainless steel should be specified to ensure compliance with relevant British Standards and Warranty Provider requirements.

2

Rigid Self Support

The unique design of the Keyfix NCCT enables the stainless steel tray to be self-supporting across the cavity and requires no support from the internal structure, eliminating clashes with other components. Standard trays can be used to protect varying cavity widths from 50mm+.

3

Requires no Sealants or Mastics

The Keyfix NCCT is the only Cavity Tray of its type on the market with a mechanical dry seal at joints. The patented ribbed joint overlap eliminates the use of any sealants at joints which removes the possibility of installation errors caused by onsite conditions.

4

Integral Stop Ends

The Keyfix NCCT incorporates integral Stop Ends on each tray to ensure water is trapped and channelled outwards via the Keyfix NCW (Non-combustible Weep). The integral Stop Ends facilitate perp joint width adjustability of +/- 3mm between 7-13mm if required.

5

No Thermal Bridge

Completely self-supporting, the Keyfix NCCT is installed in the outer leaf with no connection whatsoever with the inner skin and therefore does not create a thermal bridge or differential movement issues.

6

Onsite Simplicity

The modular system incorporating integral Stop Ends, Non-combustible Weeps, and prefabricated external and internal corner trays with ribbed joints provide bond /coursing adjustability and removes the need for onsite fabrication. Detailed component schedules and location plans ensure easy planning and ordering with stock available quickly via our extensive distribution network.

Fully Accredited Solutions

The Keyfix Non-Combustible Cavity Tray System has been awarded a BBA Certificate and is the only non-combustible cavity tray system to not rely on tapes and mastics to make watertight joints, therefore eliminating one of the main reasons for product failure.

Listed on the NHBC ‘Accepts list’, the system is approved by both Premier Guarantee and LABC following their comprehensive review of innovative products and systems.
