Sapphire is proud to announce that its G30 balcony, when used with or without StubGuard, has officially been certified as a Passive House Component by the Passive House Institute – a significant milestone that reinforces the product’s exceptional thermal and structural performance.
With developers and designers under increasing pressure to deliver low-carbon buildings that meet more stringent energy and envelope-performance standards, balcony connections have come under heightened scrutiny as a critical point of heat loss. The G30’s certification provides third-party validation that its design meets the rigorous thermal and structural requirements demanded by Passive House projects and other high-performance residential buildings.
The G30 anchor was Sapphire’s first breakthrough in ultra-rigid balcony connection technology. Engineered with M30 stainless steel studs and a 30mm thermal break zone, the G30 reduces both deflection and thermal transfer while maintaining outstanding structural rigidity. Its efficiency also means fewer anchors are required per balcony, typically just two or three, compared with older systems that could require six or more fixings. This combination of strength, performance and compatibility with lightweight aluminium balconies has made the G30 a trusted choice for high-performance residential construction.
Doug Cumming, Head of Pre-Construction and Innovation said:
“Receiving this certification marks an important achievement for our team. It reflects our commitment to innovation, sustainability, and providing builders with solutions that truly support high-performance, energy-efficient homes. Balcony connections are often overlooked, but they can make a major difference in overall building performance, and we’re proud that the G30 addresses this challenge effectively.”
Passive House Component certification is widely recognised as one of the most rigorous quality assurance processes in the built-environment sector. Products undergo stringent assessment to verify that they meet the Passive House Institute’s demanding standards for energy efficiency, airtightness and elimination of thermal bridging. For balcony connections in particular, reducing thermal bridges is essential, as these weak points can lead to increased heat loss, colder internal surface temperatures, reduced comfort and a heightened risk of condensation or mould.
Passive House criteria require that the temperature factor (fRsi) must not fall below strict limits specific to climate zone – ensuring the internal surface temperature remains high enough to avoid moisture-related issues. The G30’s design enables projects to meet these demanding requirements, supporting buildings that may, in some cases, operate without traditional heating systems.
Sapphire’s newly certified G30 anchor provides designers and developers with an independently validated, high-performance solution for delivering energy-efficient homes that align with the growing demand for low-carbon, thermally optimised building components.
