The G30 anchor was Sapphire’s first innovation in ultra-rigid balcony anchors. It uses M30 stainless steel studs and a 30mm thermal break zone to reduce deflection and thermal transfer. This system allows for fewer anchors per balcony—typically two or three—compared to older systems requiring six or more. The G30’s rigidity and compatibility with lightweight aluminium balconies have made it a standard for high-performance installation.

Now Passive House certified, the G30 sets a new benchmark in thermal efficiency and sustainability, further reinforcing Sapphire’s commitment to energy-efficient design.
