The Difference Between Laminated Glass and Insulated Glass

2023-05-11


Glass panels and insulated glass are both commonly used types of glass in modern architecture, and they have the following differences:

1. Structural differences: Laminated glass is a composite glass formed by sandwiching a layer of PVB film between two panes of glass, whereas insulated glass consists of two or more panes of glass separated by an air or gas-filled space at a specific distance.

 

2. Different functions: Laminated glass enhances a building's safety, sound insulation, thermal performance, and aesthetic appeal, whereas insulated glass is primarily used to improve soundproofing, heat retention, and light transmission in buildings.

 

3. Different costs: The manufacturing process and raw material costs of laminated glass are higher than those of insulated glass, making it relatively more expensive.

 

4. Different application scopes: Laminated glass is suitable for scenarios requiring enhanced building safety and aesthetics, such as high-rise buildings and commercial structures; while insulated glass is ideal for applications demanding soundproofing and thermal insulation, such as residential homes and office buildings.

Tempered glass is produced by first cutting ordinary annealed glass into the desired dimensions, then heating it to around 700°C—close to its softening point—and subsequently cooling it rapidly and uniformly. (Typically, 5–6 mm-thick glass is heated at 700°C for about 240 seconds, followed by a cooling period of roughly 150 seconds. For 8–10 mm-thick glass, the heating process lasts approximately 500 seconds at 700°C, with a cooling phase of about 300 seconds. In general, the heating and cooling times vary depending on the glass thickness.) After tempering, a uniform compressive stress forms on the glass surface, while tensile stress develops internally, significantly enhancing the glass's resistance to bending and impact. As a result, tempered glass boasts a strength that is more than four times greater than that of ordinary annealed glass. However, once glass has been fully tempered, it can no longer undergo any further processing, such as cutting or grinding, nor can it sustain damage. Otherwise, disrupting the balanced compressive stress could cause the glass to shatter completely into tiny fragments.
