Which material is better for balcony doors and windows?

Many people don't know how to choose balcony doors and windows. Let's take a look today.

Compared with steel-plastic balcony doors and windows, aluminum alloy balcony doors and windows have better durability, stability and firmness. Especially for balconies and sun rooms, the general advantages of aluminum alloy are incomparable to ordinary plastic steel (the large-area curtain walls of our common office buildings and hotels are all alloy aluminum). The advantage of plastic-steel balcony doors and windows is that their profiles have relatively low heat transfer coefficient and excellent thermal insulation performance, so they are used in the north. In recent years, the insulation technology of aluminum alloy balcony doors and windows has been very mature, and the insulation performance is also very good, so the main market is still aluminum alloy. Plastic steel mainly occupies a relatively low market.

When choosing aluminum alloy balcony doors and windows, it is recommended to choose aluminum alloy doors and windows with good heat insulation, heat preservation, sound insulation, noise reduction and air tightness. In the past, ordinary balcony doors and windows, first of all, there was only one side of glass, and the aluminum alloy frame was also integrally formed. Metal and glass themselves are easy to transfer heat, so the heat insulation performance is poor. At present, bridge thermal insulation is to add a plastic strip between two aluminum profiles. Because the heat transfer coefficient of plastic balcony doors and windows is very low, the heat transfer is interrupted, so it is called broken bridge. Now the commonly used glass is insulating glass, and the air layer between the two pieces of glass is very thick, so the heat transfer of the glass is also isolated by the air layer, which is a bit like the feeling of a thermos bottle. Therefore, the insulation performance of broken bridge insulation is very good.

Don't think that it is good to choose materials for balcony doors and windows, but also need to know how to install them. Because aluminum alloy balcony doors and windows need to be installed twice after the construction is completed, there are many different materials on site, such as aluminum alloy, such as stone, tile, paint, cement and so on.

Therefore, when installing balcony doors and windows, it is necessary to measure accurately, so that the distance between balcony doors and windows and buildings is not large, and it is normally controlled between 2-3 cm. ? Once the fixing is completed, the space between the door and the window will be filled with foaming agent. The foaming agent should be filled in a tight and uniform manner. Glue must be used after filling foaming agent. The interface between ceramic tile and stone is directly bonded, and the cement interface is first smoothed with cement mortar, and then bonded. After gluing, check whether there is glue leakage and whether the glue surface is irregular.

The above is a little knowledge about the selection and installation of balcony doors and windows, which can be adopted if necessary.
