1、 In the preparation stage of door and window replacement, door and window manufacturing is a very low threshold industry, and family workshop stores are everywhere
.
The price of high-quality doors and windows is not low
.
Before replacing doors and windows, owners should consider various related issues, such as which doors and windows need to be replaced? What kind of doors and windows should be replaced? How to choose all kinds of doors and windows and so on
.
Here are the answers for the owners one by one

If the quality of the door is good, just replace the door lock
.
Other interior doors and windows are subject to change
.
Understand the material of doors and windows
.
At present, the material of doors and windows mainly includes wood doors and windows, plastic steel doors and windows, aluminum alloy doors and windows, broken bridge aluminum alloy doors and windows
.
The advantages, disadvantages and prices of doors and windows made of different materials are different
.
The owners need to choose the most suitable materials according to their own needs and economic conditions
.
Wooden doors and windows: made of wood frame, wood texture strong, easy to corrosion; Sound insulation, heat insulation good first depends on the style, color, and then look at the feel, hardware accessories
.
And now the new type of wood doors and windows are mainly pure wood doors and windows and “aluminum clad wood” two types of wood doors and windows, so we should also pay attention to pure wood or aluminum clad wood
.
Plastic steel doors and windows: mainly made of high-strength anti-oxidation plastic materials, with steel as internal support, with general safety, anti-theft and ventilation quality; The thermal conductivity is the lowest, and the thermal insulation is better than the protective film on the profile surface; See whether there are anti-counterfeiting marks on the concave channel wall of profiles; Or dial the profile manufacturer’s telephone number on the protective film, and judge whether it is true or false according to the prompt quotation
.
Ordinary aluminum alloy doors and windows: aluminum alloy extruded profiles are used for frame, stile and fan materials, which are not easy to deform, aging, strong and strong; The aluminum alloy window with poor thermal insulation performance has fine processing, smooth tangent, no obvious gap and smooth switch in the splicing process
.
Broken bridge aluminum alloy doors and windows: adding a layer of resin material on the aluminum alloy window frame has the advantages of aluminum alloy doors and windows
.
At the same time, the way of heat conduction is cut off, the heat insulation is good, and the thickness, strength and oxide film of aluminum profiles used for high-quality bridge broken aluminum alloy doors and windows should meet the relevant national standards, and the wall thickness should be more than 1.2mm
.
Whether it is the final decision to choose which material of doors and windows, we should carefully study the advantages and disadvantages of this material identification method

.
The general process of door and window removal: before the door and window removal, the person in charge of door and window installation shall conduct a comprehensive safety and technical disclosure to the installation workers
