Testing and Research
Cladding & Curtain Wall Tests
We ensure the stable quality of exterior materials built to endure severe winds and heavy rains. We test the wind resistance, air-permeability and water-tightness of window and door mock-ups.
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
