Testing and Research
Cladding & Curtain Wall Tests
Our Wind Engineering Laboratory ensures the stable quality of claddings and curtain walls to endure severe wind and heavy rain.
We test wind pressure-resistance,air-tightness and water-proof performance of windows and doors.
Major testing and research activities
- ■Tests of wind resistance, air-permeability, and water-tightness.
- Testing the wind resistance, air-permeability, and water-tightness of exterior walls, curtain walls, windows, doors and others.
- ■Story drift performance tests.
- Testing the story drift performance of exterior walls and curtain walls installed on structural frames with fasteners
