Hollow Glass For Glass Curtain Wall,Windows-Insulating Glass

Insulated glass is composed of two or more layers of flat glass. Use high-strength and high-air-tight composite adhesive on all sides to bond and seal two or more pieces of glass with sealing strips and glass strips. Dry gas is filled in the middle, and desiccant is filled in the frame to ensure the dryness of the air between the glass sheets.  [1] Various glass original sheets with different properties can be selected according to requirements, such as colorless transparent float glass, patterned glass, heat-absorbing glass, heat-reflecting glass, wired glass, tempered glass, etc. and frames (aluminum frames or glass strips etc.), made by cementing, welding or welding.

The insulating glass can use 3, 4, 5, 6, 8, 10, and 12mm thick sheets of original glass, and the air layer thickness can use 6, 9, and 12mm intervals.

The thermal conductivity of glass is 27 times that of air. As long as the insulating glass is sealed, the insulating glass has the best thermal insulation effect.

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

 High-performance insulating glass is different from ordinary insulating glass. In addition to sealing dry air between the two layers of glass, a special metal film with good thermal performance is also coated on the air layer side of the outer glass. It can cut off a considerable amount of energy from the sun to the room and have a greater heat insulation effect.

The main purpose

Uses of insulating glass

 Insulated glass is mainly used in buildings that require heating, air conditioning, noise or condensation prevention, and buildings that require no direct sunlight and special light. It is widely used in residences, restaurants, hotels, office buildings, schools, hospitals, shops and other places where indoor air conditioning is required. It can also be used in doors and windows of trains, cars, ships, freezers, etc.

 Insulating glass is mainly used for outer glass decoration. Its optical properties, thermal conductivity and sound insulation coefficient should all comply with national standards. Only insulating glass with reasonable structure and standard design can exert its functions of heat insulation, sound insulation, anti-theft and fire prevention. The use of vacuumed double-layer tempered glass can even reach laboratory standards! There are also insulating glasses on the market that add inert gases and colored pigment gases, as well as adding scenic strips for reinforcement and decoration.

The role of aluminum spacers for insulating glass: Aluminum is called an active metal element, but in the air a dense oxide film will form on its surface, preventing it from interacting with oxygen and water. It can react with oxygen at high temperatures and release a large amount of heat. With this high heat of reaction, aluminum can replace metals from other oxides (thermite method)

Common categories

1. Float insulated glass

 2. Tempered insulating glass

 3. Coated insulating glass

 4.LOW-E insulating glass

 Common insulating glass: 5+9A+5 double-layer insulating glass. Shenghai Doors and Windows explained that the 5 here means that the thickness of the glass is 5mm, the 9 means that the hollow part is 9mm, and the letter A is the abbreviation of air. There are also models on the market such as 5+15A+5, 5+22A+5, 5+27A+5, 5+32A+5, etc. It is not difficult to understand the meaning of the above.

 Safety performance

 Due to the good thermal insulation performance of insulating glass, the temperature difference on both sides of the glass is large, which can also reduce the effect of cold radiation; when the outdoor temperature is -10°C, the indoor temperature in front of the single-layer glass window is -2°C while the insulating glass The temperature in front of the glass window is 13℃; in the same house structure, when the outdoor temperature is -8℃ and the indoor temperature is 20℃, the cold radiation area of ​​3mm ordinary single-layer glass accounts for 67.4% of the indoor space, while using double-layer glass Insulated glass (3+6+3) is 13.4%.

The use of insulating glass can improve the safety performance of the glass. When using the same thickness of the original glass, the wind pressure resistance of the insulating glass is 1.5 times that of ordinary single glass.
