casement window 6063T5 aluminium 0.40.4m3/m2h in air tightness 600pa in water tightness above 5000pa in wind resistance
Two sealant strips surrounding inner and outer frames reaches 0.40.4m3/m2h in air tightness, much lower than the standard 0.5-1.0 m3/m2h, for better effect in keeping suspended substance and poisonous gas outside room.
2. Structure designed in pressure principle for sealant and drainage of the system reaches 600pa in water tightness. No leakage of water under strong wind and rain on high buiding.
3. Wind resistance is above 5000pa for the 80mm and 100mm-wide frame of the system to have great effect in resisting wind, compression and distortion. Furthermore, special gasket for glass in grooves of frame would adjust the angle to avoid glass breakage and falling caused from touch between glass and aluminum frame.
4. Acoustic value of the system is 26-40dB. 21mm-wide groove for glass is apt for single glass, masked double glass with security grid and laminated safe glass. So the system can meet needs of security, energy sufficiency, and sound insulation.
5. The supporter on this system is 3mm-thick nonmagnetic stainless steel working with wheel for safer and larger loading and preventing the panes falling down.
6. The system is equipped with new products, in which raw aluminum material is International AOO electrolyzed aluminum ingot, high-quality endurable sealant strip, molded hardware fittings and nonmagnetic stainless steal screw, to guarantee longer service years.
7. Unique hooker design on outer frames and glass edges with their corresponding weather strip make the system have a better effect in air tightness, compressive strength, water and sound insulation.
