In the decoration of the common balcony, build a sunshine room, outdoor doors and windows transformation with what doors and windows better?
We mainly recommend the use of aluminum alloy doors and windows.
Why should we choose aluminum alloy doors and windows instead of plastic steel doors and windows?
Compared with steel windows, aluminum windows are more durable. In particular, the balcony and sunshine room are large areas, and the advantages of aluminum alloy are incomparable to ordinary plastic steel in the overall anti deformation degree (the curtain walls of our common office buildings and hotels are all made of aluminum alloy). The advantage of plastic steel is that the heat transfer coefficient of its profile is relatively low and the heat preservation performance is very good, so it is used more in the north. In recent years, the thermal insulation technology of aluminum alloy doors and windows has been very mature, and the thermal insulation performance is also very good, so now the mainstream market is dominated by aluminum alloy. Plastic steel mainly occupied the relatively cheap low-end market. (except for some high-end plastic steel)
How to choose aluminum alloy doors and windows?
Aluminum alloy doors and windows with heat insulation, sound insulation, noise reduction and good airtightness are recommended.
What is broken bridge insulation?
Before the ordinary doors and windows, first of all, the glass is single-sided, aluminum alloy frame is also integrated molding, metal and glass itself is easy to heat transfer, so the heat preservation performance is very poor. In the middle of the aluminum alloy, two broken plastic bars are inserted in the middle. Because the heat transfer coefficient of plastic is very poor, so the heat transfer is cut off, so it is called broken bridge. Glass now commonly used is 5 + 12a + 5 insulating glass. 12a is the thickness of the air layer between the two pieces of glass, so the heat transfer of the glass is also isolated by the air layer, which is a bit like the principle of a thermos bottle.
Therefore, the thermal insulation performance of the bridge is very good.
