In one door and window, the area of glass accounts for about 75%, which reflects the importance of glass in doors and windows. Therefore, we should understand the types of door and window glass, their functions and characteristics before purchasing doors and windows. The following E&N will introduce the functions and characteristics of various glasses.
Tempered glass is heated to the softening point of ordinary glass in the tempering furnace, and then cooled rapidly and uniformly to form uniform compressive stress on the surface; It can improve the strength and effectively improve the wind pressure resistance and impact resistance of glass. Therefore, tempered glass has the advantages of high strength, impact resistance and high safety.
Tempered glass is widely used in places with high requirements for mechanical strength and safety. Such as building curtain wall, glass furniture, sightseeing elevator, etc.
#Performance and characteristics
1. Safety: When the glass is damaged by external force, the fragments will form small obtuse angular particles similar to honeycomb, which is not easy to cause serious harm to human body.
2. High strength: the impact strength of tempered glass with the same thickness is 3-5 times that of ordinary glass.
3. Thermal stability: tempered glass has good thermal stability, can withstand 3 times the temperature difference of ordinary glass, and can withstand 300 ℃ temperature difference change.
The insulating glass is composed of two or more layers of flat glass. Two or more pieces of glass are bonded to the sealing strip and glass strip with high-strength and high air tightness composite adhesive around. The middle is filled with dry gas, and the frame is filled with desiccant to ensure the dryness of the air between the glass sheets. It has the advantages of sound insulation, heat insulation, heat preservation and anti condensation.
Insulated glass is widely used in residential, hotel, hotel, office building, school, hospital, shop and other places where indoor air conditioning is required. It can also be used for doors and windows of trains, cars, ships, freezers, etc.
#Performance and characteristics
1. Sound insulation: insulating glass can generally reduce noise by 30 dB, and inert gas can reduce noise by about 5 dB on the original basis.
2. Thermal insulation: because the interior of insulating glass is vacuum, it has dry gas, which has a good temperature insulation effect.
3. Anti condensation: as sufficient desiccant is filled in the spacing strip of insulating glass, it can effectively absorb the water vapor that may seep into the inner chamber and the outside, effectively preventing condensation.
Laminated glass refers to the composite glass with one or more layers of PVB intermediate film added between two or more pieces of glass, and then processed by high temperature preloading process, so that the glass and the intermediate film can be bonded together. It has the characteristics of high strength, explosion-proof, sound insulation, etc.
Laminated glass is widely used in building daylighting roofs, awnings, high-grade curtain walls, doors and windows, high-end residences, villas, etc.
#Performance and characteristics
1. Safety: The double-layer laminated glass can be safely broken, and will not break easily when hit by heavy objects. Even if it breaks, the fragments will remain integrated. The broken glass surface will remain smooth and tidy, greatly reducing the harm to human body, and effectively ensuring personal safety.
2. Noise reduction: PVB film can block sound waves, thus reducing noise and effectively blocking outdoor noise pollution.
3. UV protection: it has a great barrier effect (up to 99%) to the UV in the sunlight, and can protect the indoor furniture by avoiding the UV radiation.
4. Bullet proof and explosion-proof: the double-layer laminated glass has strong resistance, and its impact resistance is several times higher than that of ordinary flat glass, with a certain safety protection coefficient.
Low-E glass, also known as low radiation glass, is a film product consisting of multilayer metals or other compounds coated on the glass surface. Its coating layer has the characteristics of high transmission of visible light and high reflection of medium and far infrared light, which makes it have excellent heat insulation effect and good light transmission compared with ordinary glass and traditional coated glass for building.
#Performance and characteristics
1. Light transmittance: the light transmittance of low-e glass is 0-95%, which is high and the indoor lighting effect is good.
2. Energy saving: low-e glass has good energy saving effect. The surface emissivity of such glass is low, which can reduce the heat transfer from indoor to outdoor.
3. Beautiful: low-e glass can be made into gold, silver and other colors according to different thicknesses, materials, etc. It can adapt to different decoration styles and has certain decorative properties.
These are the introduction of several common doors and windows! As for the selection of door and window glass, I believe you have already had a basic intention. To put it bluntly, it depends on which space you want to place it in and what performance you want. Then you can choose the glass with the corresponding performance.
