What is insulating glass and is there air in the middle of insulating glass

Two pieces of glass, separated by an aluminum frame. It has the effect of sound and heat insulation.

The insulating glass that is common on the market is generally filled with inert gas in the middle. Some special requirements will be filled in the middle of the insulating glass with inert gas, which makes the thermal insulation and thermal insulation performance better. Inert gases are colorless, odorless, non-toxic gases, among which the inert gases used for filling insulating glass generally are:

Argon, krypton, and xenon.

The insulating glass is filled with inert gas in the middle layer, the inert gas is denser than the air, the thermal conductivity is smaller, which effectively slows down the thermal convection of the middle layer, reduces the thermal conductivity of the gas, thereby reducing the heat transfer coefficient of the insulating glass, and helps to improve the thermal insulation performance of the insulating glass.

Inflatable effect:

1. After argon gas is injected, the indoor temperature is 5 degrees in winter and 5 degrees Celsius in summer.

2. After argon gas is filled, the effect of the low-e film layer reflects 90% of the infrared rays in summer and plays the role of heat insulation.

3. After inflation, it can reduce the pressure difference between inside and outside, keep the pressure balanced, and the glass is not easy to burst.

4. After filling with inert gas, it can effectively improve the K value (heat transfer coefficient) of insulating glass, reduce the condensation of indoor glass, so that the glass is less prone to condensation and frosting.

5. It can slow down the thermal convection in the insulating glass, and at the same time, it can also greatly improve its sound insulation and noise reduction effect, and isolate the noise from the outside.

There is air in the middle of the insulating glass, and if there is a higher requirement for the heat transfer coefficient of the insulating glass, you can choose to fill it with inert gas. Of course, there are also those on the market that have no gas in the middle, which is no longer called insulating glass, but vacuum glass! Hope my answer is useful to you!

The common insulating glass on the market has air in the middle, which is a conventional product and is in line with national standards. Some special requirements will be filled with Sui gas in the middle of the insulating glass. True vacuum glass is rare.

The conventional insulating glass spacer is air, and if you want to improve the performance, you can fill it with inert gas, argon is commonly used.

In the case of insulating glass, it is not possible to vacuum the inside, because if the pressure inside and outside is different, the glass will take on a convex or concave shape.

Of course there is air, but it is convective with the outside air

Insulating glass is a new type of building material that has good heat insulation, sound insulation, aesthetics and application, and can reduce the weight of the building, it is a high-performance sound insulation and heat insulation glass made of two pieces (or three pieces) of glass, using high-strength and high-air-tightness composite binder, and bonding the glass sheet with the aluminum alloy frame containing desiccant.

1 Ordinary insulating glass.

Insulating glass is made up of two or more layers of flat glass. Two or more pieces of glass are bonded and sealed with sealing strips and glass strips with high-strength and high-airtightness composite adhesives around the periphery. The middle is filled with drying gas, and the frame is filled with desiccant to ensure the dryness of the air between the glass sheets.

According to the requirements, a variety of original glass with different properties can be selected, such as colorless transparent float glass, embossed glass, heat-absorbing glass, heat-reflecting glass, wire-laminated glass, tempered glass, etc., and the frame (aluminum frame or glass strip, etc.), which is made by cementing, welding or welding.

1) Technical requirements for insulating glass, the provisions of GB11944-89 are excerpted as follows:

Material AGlass can be flat glass, laminated glass, embossed glass, heat-absorbing glass, coated heat-reflecting glass, tempered glass, etc. Float glass should comply with the provisions of GB11614 first-class and excellent products, laminated glass should comply with the provisions of GB9962, and tempered glass should comply with the provisions of GB9963.

b.The sealant should meet the following requirements.

The color difference between the components of the first and second sealants used should be distinct; The validity period is more than half a year;

The second sealant for hidden frame curtain wall must be silicone sealant; Insulating glass performance requirements must be met.

c.Spacer frame: When using aluminum spacer frame, it must be decontaminated and anodized.

d.The quality, specification and performance of desiccant must meet the manufacturing and performance requirements of insulating glass.

The allowable deviation of the length and width of the insulating glass is shown in the table.

Allowable deviation in length or width (mm).

The allowable deviation of the thickness of the insulating glass is shown in the table.

Glass thickness, nominal thickness (mm), allowable deviation (mm).

Note: The nominal thickness of insulating glass is the sum of the thickness of the two pieces of glass and the thickness of the spacer frame.

The allowable deviation of the two diagonals of the insulating glass is shown in the table.

Diagonal length (mm) allowable deviation (mm).

Insulating glass was invented by the Americans in 1865 and is a new type of building material that has good heat insulation, sound insulation, aesthetic applicability, and can reduce the weight of buildings.

It is a high-performance sound and heat insulation glass made of two (or three) pieces of glass, using a high-strength and high-air-tightness composite binder, bonding the glass sheet with an aluminum alloy frame containing desiccant.

Insulating glass is a glass product that separates two or more pieces of glass evenly with effective support and is bonded and sealed around the perimeter, and the pin makes the glass layer form a dry gas space between the glass layers. Its main materials are glass, warm edge spacers, corner plugs, butyl rubber, polysulfide rubber, and desiccant.

Summary. Pro, ordinary insulating glass refers to a combination of two or more pieces of glass, but the glass contains a desiccant inside, and then the outside is bonded by an aluminum alloy frame, which brings high strength and high air tightness, and plays a role in heat insulation and sound insulation.

What does ordinary insulating glass mean.

Pro, ordinary insulating glass refers to a combination of two or more pieces of glass, but the glass contains a desiccant inside, and then the outside is bonded by an aluminum alloy frame, which brings high strength and high air tightness, and plays a role in heat insulation and sound insulation.

Compared with ordinary double-layer glass, it has superior properties and a dry gas is formed in the middle, which is composed of glass, polysulfide glue and desiccant, so relatively speaking, its thermal insulation and thermal insulation properties are very prominent, and the surface of this glass is not easy to condense frost.

There is a certain space between the glass and the glass of the insulating glass. The frame is filled with desiccant to ensure the dryness of the air between the glass sheets. The spacing between the two layers of insulating glass is generally 8mm.
