Weather proofing is an important consideration because balcony brackets have to penetrate the façade and connect back to the main slab.
There are a number of different ways of achieving water proofed solutions. To assist, Sapphire
can provide a composite sleeve (with excellent thermal properties) sleeve to shroud the arm, or can use web infills to fill the voids, and give an easier surface to weather proof against.
Many clients choose to weather proof around the arm at the point of façade penetration, however it has also be achieved at the point of the thermal break within the cavity.
