Aluminum-plastic aluminum doors and windows generally refer to aluminum-plastic composite doors and windows, with aluminum alloy extruded profiles as the main materials of frames, mullions and fans as force bars (bars that bear and transmit self-weight and load), the other side is covered with doors and windows made of plastic profiles. Aluminum plastic doors and windows and broken bridge aluminum doors and windows the differences are: different main materials, different manufacturing processes, and different within heat-conduction coefficient.
At present, there are more and more decorative materials in the market. In order to meet the needs of the public, doors and windows are no exception. Various materials have emerged, including aluminum, plastic, aluminum and broken bridge aluminum doors and windows the most representative, then, what is the difference between the two? Let's take you to understand.
What is Aluminum plastic aluminum doors and windows
aluminum-plastic aluminum doors and windows generally refer to aluminum-plastic composite doors and windows, with aluminum alloy extruded profiles as the main materials of frames, mullions and fans as force bars (bars that bear and transmit self-weight and load), the other side is covered with doors and windows made of plastic profiles.

aluminum plastic doors and windows and broken bridge aluminum doors and windows what's the difference
aluminum plastic doors and windows and broken bridge aluminum doors and windows the differences are: different main materials, different manufacturing processes, and different within heat-conduction coefficient.
I. Different main raw materials
1. Aluminum-plastic doors and windows: polyvinyl chloride (UPVC) resin is used as the main raw material.
2, broken bridge aluminum doors and windows: Use plastic profiles to separate and closely connect the indoor and outdoor aluminum alloy into a whole.
2. Different manufacturing processes
1. Aluminum-plastic doors and windows: add a certain proportion of stabilizer, colorant, filler, ultraviolet absorber, etc. to extrude into profiles.
2, broken bridge aluminum doors and windows: using heat insulation strip material and aluminum profile, the "heat insulation Bridge" is formed through mechanical opening, threading, rolling and other processes ".
3. Heat-conduction coefficient different
1. Aluminum-plastic doors and windows: plastic-steel doors and windows are of multi-chamber structure, and the heat transfer coefficient of aluminum window is 64W/M2K.
2, broken bridge aluminum doors and windows: adopt insulation broken bridge aluminum alloy profile, its heat-conduction coefficient is 1.8~3.5W/㎡ · k, which is much lower than ordinary aluminum alloy profile 140~170W/㎡ · k.
The above is about aluminum-plastic aluminum and broken bridge aluminum doors and windows what's the difference is introduced here, I hope it will be helpful to everyone.
