Dio-Met’s parapet / cavity wall glass balustrade is a building regulation compliant, fully tested solution for occurrences whereby a roof covering cannot be punctured or the parapet / cavity wall is not suitable to fix to. 

The construction of most brick walls is the same; single skin brickwork outer wall, cavity void, blockwork inner wall and topped with coping stones or capping profiles. Unfortunately this poses an installation puzzle not only for retro-fitted balustrades and ‘DIY extensions’ but this type of wall is also often drawn by architects with a glass balustrade and with no real consideration of how the balustrade might attach; since installing a balustrade bolted to only the coping stones would not be safe.

Any glass balustrade system will only ever be as strong as what it is fixed to, so to achieve the loading requirements set out in BS6180 (0.74kN for an external domestic application) at 1100mm high when fixed to a cavity wall, the balustrade system should be proven by a structural engineer.

The only workable solution, where no other provision has been made for balustrade attachment, is to transfer all the load through a substantial handrail which is in turn bolted back to the main structure of the building and this is where our Parapet Glass Balustrade provides a safe, tested solution. Wherever possible, additional fixings can be added as a custom solution to improve ridgidity.
