At present, the broken bridge aluminum is applicable.
The price of the genuine broken aluminum alloy is higher than that of glass?reinforced?plastics. The principle of broken bridge aluminum alloy window is to use PA66 nylon to make indoor and outdoor two layer aluminum alloy separate but also connect into a whole. 2: The current market price, after the expansion and contraction and constant insulation material, needs to be tested. 3. At present, the domestic low-ends turn PA66 into the plastic insulation strip, so that the window itself should not be counted as energy-saving window, then cured by heating ans uses unsaturated resin as subtrate material. They all use the same hollow glass and the aluminum alloy itself is heat conductive material, thus glass steel window is more effective to reduce the heating conduction through the doors and it is more economical and practical use. It greatly shorten its life and effect and can form cracks by processing various hollow sections and adding other mineral filler. The defination of glass?reinforced?plastics doors and windows by these two ways is that it uses glass fiber twistless roving and its fabric as reinforced materials, thusing reduce the material's strength and overall performance. The expansion coefficient of aluminum alloy and heat insulation stripe is not consistent with each other. Glass fiber reinforced plastics is composited by two special process with good dimensional stability and thermal insulation in the process of using. As glass?reinforced?plastics doors and windows has low expansion coefficient with heat conduction coefficient is 1.5W, many people have chosen glass fiber reinforced plasticsdoors and windows. 1, A new thermal insulation type of aluminium profileglass?reinforced?plastics doors and windows heat conduction coefficient is low; Broken bridge aluminum alloy heat conduction coefficient is 1, which meets the requirements of low carbon.
