1. Broken Bridge aluminum doors and windows refers to aluminum profiles, which are connected by nylon insulation strips in the middle of aluminum profiles on both sides.
2. Generally speaking, the section of broken bridge aluminum is three cavities, and the middle is a cavity formed by heat insulation strip.
3. The heat insulation strip in the middle is very similar to the bridge on the river. The function of the heat insulation strip is heat insulation. When it comes to heat preservation, the high heat transfer of aluminum is disconnected. All are usually called broken bridges.
The composition of bridge-cutoff aluminum alloy doors and windows is as follows:
1. Tempered glass: it is a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the surface of glass. When the glass bears external force, it first offsets the surface stress, therefore, the bearing capacity is improved, and the resistance of the glass itself to wind pressure, cold and summer, impact, etc. is enhanced.
2. Glass layering: the service life of the glass layering is longer than that of the sealant, and the sealant will fall off during 2-3 years of use, resulting in no heat preservation effect for Windows, however, the life of glass layering is more than 5 years, and there will be no differentiation. Therefore, it is better to choose sealing strip to fix glass than sealant when choosing broken bridge aluminum doors and windows.
3. Heat insulation strip: most of the Broken Bridge aluminum doors and windows on the market are made of PVC. PVC will expand and shrink in winter, which will become brittle and easy to break under such circumstances.
4. Aluminum profile: aluminum is divided into two types. We usually use UENSHENG aluminum and recycled aluminum. Here, Yi Ruifeng would like to remind you, because there is no difference between UENSHENG aluminum and recycled aluminum, we generally do not distinguish when looking at it, and merchants will use this to fool you.
The difference between primary aluminum and recycled aluminum is that the hardness is different!
