Characteristics and Cost Analysis of Architectural Glass
Characteristics and Cost Analysis of Architectural Glass
Glass, as a common building material, plays an important role in modern architecture. It can not only provide light and visibility, but also provide functions such as insulation, sound insulation, and fire prevention. In the field of architecture, commonly used glass types include ordinary glass, tempered glass, laminated glass, and low radiation glass, Glass product .
When selecting glass, in addition to considering its type, it is also necessary to consider the usage scenario. For example, using transparent ordinary glass in office buildings can provide a good view and natural light; In laboratory or factory environments, tempered glass with higher safety may be chosen; In places such as music recording studios or theaters, laminated glass with better sound insulation may be used.
When selecting suitable glass, cost factors should also be considered. Different types of glass have different production costs and processing difficulties. The production and processing costs of ordinary glass are relatively low, while tempered glass and laminated glass require special treatment and higher technical requirements, resulting in relatively high costs.
Classification of commonly used glass in buildings
Ordinary flat glass: Ordinary glass is the most common type of glass. It has good transparency and light transmission, but is relatively weak in terms of safety. Due to its low cost, ordinary glass is widely used in exterior walls, windows, and doors of buildings.
3-4 cm glass, this specification of glass is mainly used for the surface of picture frames.
5-6 cm glass, mainly used for small transparent shapes such as exterior walls, windows, door leaves, etc
7-9 cm glass, mainly used in larger areas such as room screens but with frame protection in the design.
9-10 cm glass can be used for decoration projects such as large area partitions and guardrails.
11-12 cm glass, can be used in floor spring glass doors and some partitions with high pedestrian flow.
Glass with a thickness of 15 cm or more is generally sold less on the market and often requires ordering. It is mainly used for large areas of floor spring glass doors, exterior walls, and whole glass walls.
Tempered glass: It is a type of pre-stressed glass. To improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external forces, it first offsets the surface stress, thereby improving its load-bearing capacity and enhancing its own wind pressure resistance, impact resistance, etc.
Performance:
1. Safety. When glass is damaged by external forces, the fragments become small obtuse angle particles resembling honeycomb shapes, reducing damage to the human body.
2. High strength. The impact strength of tempered glass with the same thickness is 4-5 times that of ordinary glass, and the bending strength is 3-5 times that of ordinary glass.
3. Thermal stability. Tempered glass has good thermal stability, can withstand a temperature difference of three times that of ordinary glass, and can withstand temperature changes of 200 ℃.
4. Tempered glass cannot be cut;
5. Tempered glass has the characteristic of self explosion. Self explosion refers to self explosion that occurs without external mechanical force.
Usage: 1. Widely used in glass curtain walls, doors and windows, partitions, guardrails, bathrooms, furniture, household appliances, and other places that require glass strength and safety protection for the human body.
Processing circumference size: maximum 2440mm x 5500mm; Minimum 200mm x 250 thickness: tempered 4-25mm, semi tempered 3-19mm
Laminated glass consists of two or more thin and hard glass sheets sandwiched between them by a PVB thin film layer. This structure provides excellent safety and sound insulation effects to laminated glass, preventing fragmentation and absorbing sound. Therefore, laminated glass is commonly used in places that require sound insulation and protection such as high-rise buildings, airports, hospitals, etc.
Laminated glass: Laminated glass is a composite glass product consisting of two or more pieces of glass sandwiched between one or more layers of organic polymer intermediate film. After special high-temperature pre pressing (or vacuum pumping) and high-temperature high-pressure processing, the glass and intermediate film are permanently bonded into one.
Performance: When damaged, the fragments still adhere to the adhesive layer, avoiding damage to the human body caused by debris splashing.
Processing circumference: size: maximum 2500mmx10000mm; Minimum 300mm x 300mm
Purpose: Mainly used for decoration projects with safety requirements.
LOW-E glass: Low-E glass, also known as low radiation glass, is a film product composed of multiple layers of metal or other compounds coated on the surface of the glass. Its coating layer has the characteristics of high transmittance to visible light and high reflection to mid to far infrared, making it superior in thermal insulation and good transparency compared to ordinary glass and traditional architectural coated glass.
Performance: Close to the natural primary color of glass. It has a high transmittance to the visible light band of wavelength, which does not cause serious anti glare pollution due to the high reflectivity of glass to visible light.
Usage: The correct combination method is suitable for modern green buildings in subtropical areas with relatively hot climates (such as energy-saving glass curtain walls and skylights).
Processing circumference: thickness: 3-19 mm, maximum size: 100 ″ × 144 ″ (2540 mm × 3658 mm) Minimum size: 12 ″ × 36 ″ (305 mm × 914 mm)
Hollow glass: It is a high-efficiency soundproof and heat-insulating glass made by bonding two (or three) pieces of glass with high-strength and high airtightness composite adhesive and aluminum alloy frame containing desiccant.
Hollow glass has multiple superior properties compared to ordinary double-layer glass, which has been recognized by various countries around the world. Hollow glass is a glass product that effectively supports and evenly separates two or more pieces of glass, and is bonded and sealed around, forming a dry gas space between the glass layers. Its main materials are glass, warm edge spacers, corner bolts, butyl rubber, polysulfide rubber, and desiccants.
Performance: The thermal conductivity of glass is 27 times that of air, and as long as the insulating glass is sealed, it has the best insulation effect.
Purpose: Hollow glass is mainly used for heating, air conditioning, noise prevention or condensation prevention, as well as for non direct sunlight and special needs
