2、 Performance index of U-shaped glass wall:

Wind pressure deformation performance (kPa): 4.0 ≤ P3 < 5.0 class II

Rainwater leakage performance (PA): 1000 ≤ P < 1600 class III

Air permeability (m3 / (m * h)): 0.05 < Q ≤ 0.1 class III

Insulation property K (w / (M2 * k)): 1.1 ≤ Q ≤ 4.9

3、 U-glass specification:

U-shaped glass bottom width: 220mm, 230mm, 260mm, 300mm, 330mm, 350mm, 400mm, 450mm, 500mm;

U-shaped glass wing height: 41mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 100mm, 110mm, 120mm;
