When changing windows at home, should one choose broken bridge windows or plastic steel windows?
I. In terms of material
1. Broken bridge windows:
- Broken bridge windows mainly use aluminum alloy material, which is high in strength and durable.
- After surface treatment, it has good corrosion resistance and aesthetics.
- Broken bridge aluminum alloy divides the aluminum alloy profile into internal and external parts through thermal insulation strips on the basis of ordinary aluminum alloy profiles, effectively blocking the conduction of heat.
- Plastic steel windows are extruded profiles made mainly of polyvinyl chloride (PVC) resin, plus a certain proportion of stabilizers, colorants, fillers, etc.
- Plastic steel windows have good thermal insulation and sound insulation properties, but their strength is relatively low.
- The appearance color of plastic steel windows is relatively single, generally white or gray.
**II. Regarding thermal insulation strips**
1. Broken bridge windows:
- The thermal insulation strips of broken bridge windows generally use nylon PA66 material, which has good thermal insulation performance and strength.
- The quality of thermal insulation strips directly affects the thermal insulation effect and service life of windows. High-quality thermal insulation strips can effectively block the conduction of heat and reduce the energy consumption of indoor air conditioners and heating.
- The thermal insulation performance of plastic steel windows mainly depends on the plastic material itself. Although plastic steel windows have certain thermal insulation performance, compared with broken bridge windows, their thermal insulation effect is slightly inferior.
- After long-term use, plastic steel windows may have problems such as deformation and aging, which will affect their thermal insulation performance.
III. In terms of price
- The price of broken bridge windows is relatively high. Due to the use of aluminum alloy material and high-quality thermal insulation strips, the production cost is high.
- In addition, the production process of broken bridge windows is relatively complex and requires professional equipment and technicians for processing and installation.
- Generally speaking, the price of broken bridge windows ranges from several hundred yuan to several thousand yuan per square meter. The specific price depends on factors such as the specification, model, and brand of the window.
2. Plastic steel windows:
- The price of plastic steel windows is relatively low. Due to the low cost of the plastic material used and the relatively simple production process.
- The price of plastic steel windows generally ranges from several dozen yuan to several hundred yuan per square meter. The specific price also depends on factors such as the specification, model, and brand of the window.
IV. Differences in other aspects
1. Sealing performance:
- Broken bridge windows generally adopt multi-channel sealing design with good sealing performance. It can effectively prevent the intrusion of external factors such as rain and wind, and at the same time reduce the convection of indoor and outdoor air and improve indoor comfort.
- The sealing performance of plastic steel windows is also relatively good, but after long-term use, problems such as aging and deformation of the sealing strips may occur, thus affecting their sealing performance.
2. Durability:
- Broken bridge windows have better durability. Aluminum alloy material has high strength and corrosion resistance and can withstand long-term wind, sun, and rain. At the same time, high-quality thermal insulation strips can also ensure the service life of windows.
- The durability of plastic steel windows is relatively poor. After long-term use, the plastic material may have problems such as aging and deformation, which will affect the service life of windows.
