How can there be a whistle after the aluminum alloy doors and windows seal the balcony and close the

Broken bridge aluminum alloy profiles or aluminum-wood composite profiles are relatively high-grade door and window profiles, which not only have good visual effects, but also have good sound insulation and thermal insulation effects. I hope my answer can help you.

Theoretically, the thicker the profile, the higher the strength, but the common specifications of the window can meet the needs of daily use, and there is no need to pursue the maximum thickness.

You can also use plastic steel doors and windows, the sealing degree of plastic steel doors and windows is higher than that of aluminum alloy, especially in the Northeast winter, the insulation is particularly good, and the lighting is also very good!

As far as plastic steel and aluminum alloys are concerned, plastic steel is good. Now there is a new one called broken bridge aluminum, which is better 1He has better temperature insulation than aluminum alloy, aluminum alloy in winter, how cold he is outside, how hot he is outside in summer, how hot he is in summer, plastic steel will not be like this. >>>More
