?Jewel Sun aluminum with wood cladding windows are new energy saving building windows, taking composite material combined by aluminum, wood and PVC as its frame material, which can effectively reduce the loss of heat, avoid the radiation and prevent the convection and conduction of heat. The circular flow of warm current of air and cold current of air in the space of the windows makes the ventilation smoothly.
The outside bridge-cut-off aluminum alloy is durable, and reserves excellent weatherability, tidiness and precision of aluminum alloy windows. The inside high-quality wood is processed by particular technics, which embodies all the features of top grade windows. The main materials of the principle structure are high-quality laminated natural pine lamina inside, and heat insulation bridge-cut-off aluminum alloy outside. Jewel Sun aluminum with wood cladding windows utilize high quality German hardware, and compatible with high-performance hollow glass with glass of 5+12A+5 thickness, added imported good EPDM sealing joint strip. The windows are energy saving and environmental products elaborately made according to state standard. Main Performance Index of the Standard Configuration
