The price difference between high-grade aluminum alloy doors and windows and general aluminum alloy doors and windows is very big. In addition to brand factors, sound insulation is also an important comparative parameter. High grade excellent aluminum alloy doors and windows can effectively isolate noise, but also a quiet indoor living environment. The difference of sound insulation technology is as follows:

1. The sound insulation effect of single-layer glass with double-layer insulating glass is relatively poor. To achieve sound insulation, double-layer hollow is the basic configuration, which increases the sound penetration thickness and has the effect of physical noise reduction.

2. Hollow bending treatment hollow aluminum strip is bent by hollow bending machine, and only one interface is left for the hollow aluminum strip of a door and window, which reduces the number of interfaces, reduces the possibility of air circulation, forms a vacuum, and achieves the ideal noise reduction effect.

3. In addition to reducing the interface of the hollow aluminum strip, the sealing treatment of glass glue is also very important. Apply glass glue around the hollow aluminum strip to form a vacuum between the two glasses, so as to achieve the best sound insulation effect.

Small manufacturers in order to save time and cost, the second and third step is directly omitted, the product appearance difference is not big, but the practicability is greatly reduced. In order to achieve the best noise reduction effect, liefan aluminum alloy door and window manufacturers have introduced large-scale hollow bending machine. Each door and window is treated with sound insulation to achieve the best sound insulation effect.
