Yancheng Talent Apartments: FRP Window Supply for a Coastal Housing Development
One pultruded FRP window system for about 20 coastal mid-rise buildings in Yancheng: casements, balcony sliders and facade frames, delivered in phases over 14 months.
FIG. 1 Apartment development
The challenge
The Yancheng Talent Apartment development in Jiangsu is a government-backed complex of about 20 mid-rise apartment buildings, a commercial plaza and community facilities, built to house skilled workers on regional industrial and R&D programmes. Yancheng lies less than 40 km from the Yellow Sea, and the salty, humid air is hard on coated aluminum frames, which typically need repainting after 8–12 years. The specification asked for: (a) a whole-window U-value below 1.6 W/m²K under the local residential energy code, (b) sound reduction above 32 dB, (c) one consistent appearance across thousands of units, (d) several window types in one pultruded system: inward and outward casements for the flats, large sliders for the balconies and framed glazing for the commercial and clubhouse facades, and (e) deliveries phased over a 14-month build with no storage space on site.
What F1 supplied
F1 supplied the whole window package from three pultruded FRP product families. The flats received 65-series casement frames in inward- and outward-opening versions; the 65 mm frame depth with a double-glazed unit meets the 1.6 W/m²K target, and the FRP profile needs no thermal-break insert. Balconies and terraces used 90-series multi-track sliding frames with clear openings up to 2.4 m, reinforced interlock mullions and stainless-steel rollers for daily use. The commercial plaza, clubhouse and facade areas used 90-series framed glazing with the same sightlines, so the architects could keep one frame look across residential and non-residential buildings. All profiles were pigmented dark grey through the section, so there is no paint layer to renew. Lengths were cut and corner joints pre-drilled in the factory, and batches were shipped straight to the installer to match each building's glazing schedule.
Results
F1 delivered the full window package for all residential and commercial buildings on schedule over the 14-month programme. One supplier covered the 65-series casements, the 90-series sliders and the facade frames, which kept the U-value, acoustic and appearance requirements consistent across the site. After the first winter and summer, the post-handover inspection found no UV fading and no salt-air damage on the dark grey profiles.
