The challenge

Qinling Station, China's research station on the Ross Sea, opened in February 2024. Its windows had to cope with Antarctic conditions and a short shipping season: the project account gives a design low of about −60 °C and winds up to 45 m/s. Those site conditions go well beyond the climate zone covered by the window's PHI component certificate.

What F1 supplied

The windows used 90-series GFRP frames with insulated glazing, assembled in the factory. The related document is PHI component certificate 2491wi03 for the Fengdu Passive GFRP 90 Series, issued to Chongqing Xianju New Material Co., Ltd., a FengDu subsidiary. It certifies the window for the cool-temperate climate zone at efficiency class phB, with Uw 0.78 W/(m²·K) and Ug 0.70, valid until 31 December 2026. It is not an Arctic rating and does not cover the station as a whole. For a similar project, ask for the drawings, assembly tests and acceptance records of the configuration actually supplied.

Results

Qinling is F1's reference for GFRP windows in extreme cold. The PHI certificate on its own does not prove Antarctic wind resistance, service life or fuel savings for every installed unit; those need project-specific tests and supply records.
