Uw for numerical simulation of Uf = 1.36 w/m squared. K, Ug = 1.45 w/m squared. K, Ψ g = 1.45 w/m.k window size: 1230 x1480mm
1. The main profile high wall thickness large cross section design, chamber structure, visual wall thickness of 2.8 mm, or three seal design, excellent heat preservation and heat insulation performance.
2. Three glass two hollow glass according to the 5 + 9 a + 5 + 9 a + 5, 5 + 9 a + 5 low-e standard configuration, the biggest glass thickness 42 mm, improve sound insulation heat preservation performance.
3. Profile fruity and elegant appearance, smooth surface and fine porcelain texture.
4. Body water slope structure glue, seal more efficient, independent drainage chamber, head type more unobstructed drainage.
