Barrier and handrail fixings

While you may not consider it the most aesthetic solution, B1/AS1 gives one design option as a deemed-to-comply solution for the design and fixing requirements for a timber handrail/barrier to a deck. Where a glass, aluminium or other barrier solution is proposed, it will need to be specifically engineered to meet the loadings given in AS/NZS 1170 for barriers. Specific design will be required for the structural connections of the barrier to the deck and adjacent walls. Where the barrier provides protection against falling from a waterproof deck, such fixings must be designed to ensure the performance requirements of clause E2 External moisture will be met (although no details are provided in E2/AS1).
