Broken bridge aluminum doors and windows use thermally insulated broken bridge aluminum profiles and hollow glass, which have the functions of energy saving, sound insulation, noise prevention, dustproof, and waterproof. The thermal conductivity K value of broken aluminum doors and windows is below 3W/㎡·K, which reduces heat loss by half compared with ordinary doors and windows, reduces heating costs by about 30%, and has a sound insulation of more than 29 decibels. It has good water and air tightness, reaching Class A1 Window standard.

Pros and cons of broken bridge aluminum doors and windows:

1. Look at the surface quality of the profile

The quality of the profile can be observed from the surface of the broken bridge aluminum profile. The surface of the good broken bridge aluminum profile is shiny and textured, and the surface spraying color treatment will also be natural, and it will feel smooth when viewed; the second broken bridge aluminum doors and windows have rough surfaces. There is no luster, and it looks unnatural. After a period of use, the poorly broken aluminum doors and windows will appear discolored or faded, and the color will not be full.

2. Look at the section structure of the profile

The geometric angle of the cut surface of a good broken aluminum door and window profile is accurate, the profile will not be bent or twisted, and the angle is correct. And the thickness of the cut surface is sufficient, such as your customized 60 model broken bridge aluminum doors and windows, 60 refers to the profile thickness of 6 cm, and these 6 cm are full of broken bridge aluminum materials, which account for a small proportion of the penetration; For the broken bridge aluminum doors and windows, the dummy 60 profile will be used, and the thickness will be supported by the piercing strips, and the aluminum material is relatively small.

3. Look at the heat insulation strip of the profile

The insulation strips are made of PA66 insulation strips and PVC insulation strips. The insulation strips with good performance are nylon insulation strips. High-quality broken bridge aluminum doors and windows, using PA66 heat insulation strips, which have better high temperature resistance and low temperature resistance, low thermal conductivity, and can achieve the effect of thermal insulation, environmental protection and energy saving, and can save energy by 20%-30% .

It is recommended not to use PVC insulation strips. Although the price is low, it does not have three major functions (airtight, watertight, wind pressure resistance) and heat preservation, heat insulation, and attraction properties. The role of PVC insulation strips can be said to be It's better than nothing.
