G.James Testing Laboratory

The G.James Testing Laboratory began operation in November 1989 with testing the curtain wall faµade for the Chifley Tower project in Sydney. Since this time the laboratory has achieved NATA accreditation (1992) and completed over 150 tests on various G.James windows, sliding doors and custom curtain wall combinations. These tests have been both for specific projects and the research and development of various G.James aluminium framing systems and glazing techniques.

This in-house testing facility allows G.James to firstly, provide customer satisfaction through the performance and compliance of our products and secondly, achieve customer confidence by continuing to supply products that reflect outstanding reliability and quality.

The main function of the G.James Testing Laboratory is to service the requirements of the G.James Group and for this reason there is limited availability for external testing.
