The temperature outside in winter is very low, and people can often feel the constant invasion of cold when they are at home. So the market out of the doors and a door and window insulation is warm, the insulation material sash windows and doors, glass thickness, shape and even sealing of windows have decided whether it allows you to spend a warm winter. So, how do we buy thermal insulation, thermal insulation, sound insulation doors and windows? Let's take a look at the method of purchasing thermal insulation doors and windows and the considerations for the selection of doors and windows.
How to choose insulation doors and windows
1. Aluminum alloy profile
The disadvantage of plastic-steel frame material is that it is easy to ventilate after a long time, and the gap at the interface is too large to bond. Therefore, it is preferred to purchase doors and windows in winter with good thermal insulation and sound insulation effects. Aluminum alloy materials are good conductors of heat, and most of the thermal conductivity is relatively high. The sealing performance of the broken bridge aluminum doors and windows is relatively better. The heat conduction channel of the broken bridge aluminum can achieve thermal insulation and sound insulation.
2. Glass
Insulation and sound insulation doors and windows need to use hollow glass, because the cavity between the hollow glass is filled with dry and still air, which greatly reduces the thermal conductivity, so the hollow glass has excellent heat insulation, sound insulation and anti-frosting, condensation performance.
3. Sealing material
The sealant used for thermal insulation and sound insulation doors and windows should be weather-resistant adhesive. The sealant strip should be made of neoprene with excellent resistance to ozone corrosion and ultraviolet aging. The opening and closing of the door and window should be provided with more than three sealant strips.
What to pay attention to when buying doors and windows
1. Fire resistance
Recently, several fires in high-rise buildings have raised concerns about the fire resistance of windows. Ordinary building exterior windows are the openings of the building's outer protective structure, and are an important channel for the upward spread of the fire jump layer. Therefore, it is an important measure to reduce the fire loss and casualties by improving the fire resistance of the exterior windows in advance and effectively preventing the fire from spreading rapidly.
2. Sound insulation
Hollow structures are used for building exterior windows with sound insulation function. Generally, two layers of float glass with strong texture, durability and resistance to wind pressure are used. Some hollow glass structures with more than two layers of glass are used to enhance the sound insulation function. It is understood that a window with two layers of insulating glass will be sealed at the junction of the frame glass and the profile with a ring of rubber strips and two rings of tops to improve the sealing of the window to achieve the purpose of enhancing the sound insulation function.
3. Security
After installation, you should pay attention to check whether the entire window is deformed, whether the sash is flexible to open, whether the window and the wall are firmly jointed, and there is no gap, and the protective film on the surface of the window material should be removed in time. In addition, occupants living in buildings with more than seven floors cannot install windows with sashes opening outwards to avoid the wind blowing the sashes off.
The above introduction is believed to be of some help to everyone. The insulation doors and windows are still very practical. The good helper for the cold is it. If you like the above introduction, please continue to pay attention to this website, for more exciting stay tuned!
