Which is better, broken bridge aluminum doors and windows hollow 18A or 20

What is the relationship between the insulation of broken bridge aluminum doors and windows and the performance of broken bridge aluminum doors and windows.

18a and 20a refer to the thickness of the hollow insulation strip, that is, the thickness of the hollow, 20 is thicker than the middle air layer of 18, and the effect will definitely be better.

Of course, 20 is good, it is double-enclosed.

The insulating glass used in the broken bridge aluminum doors and windows, the larger the interval, the better the sound and heat insulation effect.

Applications of double-layer insulating glass:

Insulating glass was invented by the Americans in the 19th century, and insulating glass seals the air between two layers of glass through sealing processing, thus playing the role of heat insulation, heat preservation, and defrosting. At the beginning of the 21st century, insulating glass has just entered the homes of our Chinese people, and has now become the standard glass configuration in plastic steel doors and windows and broken bridge aluminum doors and windows.

Common insulating glass includes ordinary insulating glass, vacuum glass and special insulating glass filled with inert gas in the middle.

Structural analysis of double-layer insulating glass:

Two layers of glass, separated by an aluminum spacer in the middle, filled with desiccant in the middle, and resealed with tincture silicone sealant around the perimeter. So as to ensure that the inside of the insulating glass remains dry for a long time, and there is no moisture and dust.

Parameter description of double-layer insulating glass:

Examples of common insulating glass parameters, e.g. 5+9A+5 double-layer insulating glass. The 5 here refers to the thickness of the glass is 5 centimeters, 9 refers to the hollow part is 9mm, and the letter A is the abbreviation of English air.

There are also models on the market 5+15A+5, 5+22A+5, 5+27A+5, 5+32A+5, etc., knowing the meaning of the above, it is not difficult to understand, they are all 5 mm of two-layer glass, and the separation distance in the middle is different. The larger the spacing, the better the sound and heat insulation.

I don't know, I make insulation boards!

In the 21-storey high-rise building, it is enough to use 85 broken bridge aluminum, mainly depending on where the broken bridge aluminum is used. The so-called 85 broken bridge aluminum, in fact, means that the thickness of the broken bridge aluminum material is 85 mm, if the broken bridge aluminum itself is thicker, then the final sealing performance of the window will definitely be better. If you need to buy broken bridge aluminum doors and windows, it is recommended to choose Zhengjin doors and windows.

The advantages of broken bridge aluminum doors and windows are as follows:

1. Reduce heat conduction.

The use of heat-insulated bridge aluminum alloy profiles effectively reduces the heat conduction through doors and windows.

2. Prevent condensation.

The temperature of the inner surface of the profile with insulating strips is close to the room temperature, reducing the possibility of indoor moisture condensing on the profile surface due to oversaturation.

3. Energy saving. In winter, window frames with insulating strips reduce heat loss through the window frame by 1 3. In summer, if there is air conditioning, window frames with insulating strips reduce energy losses even more.

If you want to know more about the broken bridge aluminum doors and windows, it is recommended to consult the Zhengjin doors and windows that have obtained the China Green Building Materials Product Certification. Zhengjin doors and windows belong to Foshan Deslaisi Home Technology ****. Focus on aluminum alloy doors and windows, sun rooms and other customization.

The brand is based on the strong profile, glass and surface treatment advantages and complete ** system of Des-Royce Group. Zhengjin doors and windows began to integrate R&D, production, sales and service, and is an early large-scale enterprise in China committed to the development of high-end aluminum alloy doors and windows and sunshine room customization.

Summary. Broken bridge aluminum windows hollow 20 is better than 18, broken bridge aluminum windows are basically made of 5 + 9 + 5 or 5 + 12 + 5 insulating glass, it is two layers of 5mm glass between the gap of 9mm or 12mm, because the conductivity of glass and air is different, so as to play the effect of thermal insulation and sound insulation. Broken bridge aluminum is almost always made of such insulating glass, and what you need to choose is whether it needs to be tempered or not, whether it is single tempered (tempered on one side of the outdoor side to prevent injury to pedestrians after bursting) or double tempered (tempered on both sides, which is safer, especially to prevent impact from indoors).

Broken bridge aluminum windows hollow 20 to 18 better.

Broken bridge aluminum windows are basically made of 5+9+5 or 5+12+5 insulating glass, which is a gap of 9mm or 12mm between two layers of 5mm glass, because the conductivity of glass and air is different, so as to have the effect of thermal insulation and sound insulation. Broken bridge aluminum is almost always made of such insulating glass, what you need to choose is nothing more than whether the large chain needs to be tempered, whether it is single tempered (tempered on one side of the outdoor to prevent injury to pedestrians after bursting) or double tempered (both sides are tempered, which is safer, and Li infiltration especially prevents impact from indoors).
