It is 1/1250 of Aluminium,1/1500 of Matel,1/40 of Cement,1/20 of clay.2sound insulationFor the three-chamber-cavities' design, after welding,  Profiles will form two separate sealed cavities and an  open drainage cavity. It is tested that the window with  5mm thickness single-layer glass , noise <20db. That is consistent with the provisions of DIDN41093resistance to weatheringWith add a modifier and UV absorbers in PVC profile , It will not to be aging , not to fading and not to be brittle between 70 °C -30 °C 4flame resistanceThe profiles for UPVC windows and doors is not spontaneous, not combustion. It also can be self-extinguishing.5shock resistanceIt will not broken under the shock of the hammer with 1 KG at -10 °C ,because of the special shock resistance formulas.6watertightnessWater absorption <0.1%, frame and sash are designed with separate drainage systems, rain water can completely cut off from the outside, water tightness meets the requirement of DIDN18055.7air tightnessThere is a rubber seal between the window frames and the glass. and there is sealed strip between the frame and the leaf.  It is tested that the gap per unit length of ventilation is under 4m3/mm/hm . The air conditon can work very well in the house and save energy .8decay resistancePVC doors and windows can be decay-resistance ,gas-resistance . Suitable for coastal areas, heavy industry.Good ventilation,the free aera of ventilation is  90% of the whole window.Excellent sealing performance, better than sliding windows.For the rotating device adopts friction hinge, casement will be savety under the 8-level wind.Multi-point locking device to lock, which improved greatly the air-tightness of the window.
