Key Considerations For MOD Sites

Due to the sensitive nature of this project, details have been made deliberately ambiguous, however, it is important to note that the core aim for infrastructure on all MOD sites is as follows:

Infrastructure is a key enabler of Defence capability, the vision for which remains: Infrastructure that is optimised, affordable and supports our Defence capabilities, outputs and communities both now and in the future.

Ministry of Defence: Building Performance Standards

With this in mind, it was clear that our partners at Fifth Elevation needed a solution that was robust, efficient and effective to meet the rigorous demands of an MOD facility.

Supplying A Secret Fix Aluminium Coping System

HJA’s secret fix coping system was the natural choice for Fifth Elevation’s project for a number of reasons:

  • Anti-Rattle functionality
  • Wind-tested to 144mph
  • The coping itself delivers a clean visual line that is watertight (due to there being no bolts on the system)
  • Super quick installation
  • Strong aluminium
  • Clip on installation
  • Prevents cold bridging
  • Exceptional weatherproofing capability
  • Low maintenance

All these benefits (and more) combined, ensure a durable, long-term solution for the end-client.

The ease of installation can be seen in the below video – which the team at Fifth Elevation filmed to demonstrate its simplicity. 


We partner with a variety of roofing and cladding companies and work hard to maintain positive relationships with them. The team over at Fifth Elevation are no exception and were very pleased with the finished result.

Their team of installers were able to fit approx. 30 meters of the secret fix coping system in a few hours, making for an efficient, high-quality solution.
