Hollow glass is a type of composite glass that consists of two or more layers of glass plates separated by sealed strips or aluminum spacers, leaving a certain gap (i.e., air layer) between them. It comes in various types and specifications, and below are the main types and specifications of hollow glass:
1. Types
Ordinary hollow glass:
It uses float/flat glass as the main material, separated by sealed strips or aluminum spacers to form an air layer between two or more glass plates.
It is suitable for various occasions such as home decoration and commercial buildings.
Low-E hollow glass:
Based on ordinary hollow glass, it uses Low-E glass as the main material. Low-E glass, also known as low-emissivity glass, is a product with a multi-layer metal or other compound coating on the glass surface.
It has excellent thermal insulation properties and good light transmittance, suitable for commercial buildings such as shopping malls and office buildings.
Tempered hollow glass:
It uses tempered glass as the main material. Tempered glass is a type of pre-stressed glass that forms compressive stress on the glass surface through chemical or physical methods, enhancing its load-bearing capacity.
It has resistance to wind pressure and external impact, suitable for various installation occasions, especially in places requiring high safety.
Laminated hollow glass:
It consists of one or more layers of PVB film sandwiched between two or more glass plates, forming a hollow structure.
It has high safety and sound insulation performance, suitable for places requiring high sound insulation and safety.
2. Specifications
The specifications of hollow glass are usually expressed in the form of "glass thickness + air layer thickness + glass thickness", for example, "5+12A+5" indicates that there are two 5mm thick glass plates with a 12mm air layer in between. Here are some common specifications:
Single hollow glass:
Specifications such as: 4mm+6A+4mm, 5mm+12A+5mm, etc.
It has good sound insulation, thermal insulation, and waterproof performance, but the thermal insulation effect may not be as good as double hollow glass.
Double hollow glass:
Specifications such as: 5mm+9A+5mm+9A+5mm, 6mm+12A+6mm+12A+6mm, etc.
It has excellent sound insulation, thermal insulation, and waterproof performance, suitable for most occasions.
3. Hollow glass:
Specifications such as: 5mm+6A+5mm+9A+5mm+12A+5mm, 6mm+9A+6mm+12A+6mm+15A+6mm, etc.
Its sound insulation and thermal insulation performance are better than double hollow glass, suitable for places with high noise pollution.
In addition, there are four hollow glass, five hollow glass, and other hollow glass with more layers, which have similar specifications and performance but are suitable for more specific occasions.
In summary, hollow glass comes in various types and specifications, and when choosing, it is necessary to consider the specific usage needs and occasions. At the same time, it is also important to choose reliable quality products to ensure their performance and safety.
