Complete Guidance of Custom Architectural Glass (2020)

There are so many types of architectural glass nowadays. Most of us might not even have heard of them before. But architectural glass world is amazing and full of fantasy. Let’s explore the construction glass world here with Shenzhen Dragon Glass!

1, Float Glass

Float glass is also called annealed glass, flat glass, etc. The process of float glass production is completed in a tin bath within protective gas. The molten glass flows continuously from the pool kiln and floats on the surface of the dense tin liquid. Under the action of gravity and surface tension, the glass liquid spreads and spreads on the tin liquid surface and form a smooth surface. During the transition of glass, it is under the annealed process and continue cooling down to room temperature.

Clear float glass is most commonly used. Others such as ultra clear(low iron), tinted glass, reflective coated glass are also available.

Applications of float glass: glass doors and windows, railings, partition walls, glass office, glass shopfront, etc. Providing wind protection and heat preservation.

Good quality float glass has no bubbles no chips no scratches with a super smooth surface.

We offer super high quality float glass for sale:

Thickness of float glass: 1.8~25mm.

Color of float glass: low iron, clear, grey, blue, green, bronze, pink, etc.

Size: 2140*3300, 2140*3660, 2440*3300, 2440*3660, etc customized glass size available too.

2, Tempered glass

Tempered glass is also called toughened glass, tampered glass in different areas or different countries. It is produced by heating the glass to a temperature around 650 degrees, and then cool down the glass rapidly by a strong wind jet to form compression stress on the glass surface whereas the interior still in tension stat. It has good mechanical properties and high thermal resistance.

Tempered glass panels have 5 times higher strength than normal annealed glass panels. It can withstand a very high impact without breaking. Even if it is broken due to extremely high impact, the whole piece of glass is broken into small obtuse angle small particles, which will not harm humans, so it is also called safety glass.

Tempered glass cannot be cut. The glass needs to be cut to size before tempering.

Tempered glass panels are widely used as glass doors, architectural glass curtain walls, escalator glass fences, glass display cabinets, glass railing, glass windows, etc.

3, Heat strengthened glass (Half tempered glass)

Heat strengthened glass is also called semi-tempered glass or half tempered glass, it is produced similar to the tempering process. After float glass is cut to custom sizes, it will be edged and drilled and later transferred to a tempering machine, by heating to around 700 degrees and later cool down rapidly by the strong wind jet. The difference between heat strengthened glass production vs tempered glass production is that the cooling down the speed of heat strengthened glass is much slower than tempered glass. Therefore the heat strengthened glass is only 2 times strength higher than normal annealed glass. But the advantage for heat strengthened glass is that the surface of it is much flatter and more spotless than tempered glass. Half tempered glass is widely used where less strength & better flatness is required such as laminated curtain wall, low rise windows, etc. Semi tempered glass will not spontaneously break.

The original piece of glass is heated in a hot bending furnace to glass softening point and later cools down slowly to room temperature. During the cooling process, it will form a specific shape according to the mold by its weight. 

Two pieces of hot bending glass can be further compounded into a hot bending laminated glass.

Application of hot bending glass: Architectural arc curtain walls, doors, and windows glass, artistic table tops, etc.

Thickness: 3mm~15mm, etc.

5, Frosted glass:

There are generally two types of frosted glass.

Sandblasted glass

Sandblasted glass is also called sandblasting glass, it is using a strong wind jet to blow sand or other metal materials on the surface of the glass to form certain patterns, which can have an obscure glass effect. Sandblasted glass is widely used as partition glass wall, windows, shower rooms to achieve privacy functions.

Before the production of sandblasted glass, we can adhere to some stripe on the glass to form different shapes, patterns of the sandblasting glass. Later transfer the glass to the sandblasting machine to form different sandblasted glass designs! Here are pictures for reference:

Acid etched glass

Acid etched glass is the other type of frosted glass, it is produced by using chemical material such as Hydrofluoric acid to make the glass surface rough and form an obscure effect. Mostly acid etched glass is used in glass offices, glass partition walls, shower room glass, etc where privacy is required.

Advantages:

1, compared to sandblasted glass, acid etched glass has a smoother surface which can provide soft-touch feelings and no fingerprint.

2, Multiple patterns available for decorations.

3, easy to clean.

6, Laminated glass

Laminated glass is made by combining two or more pieces of glass “sandwiched” with pvb or sgp or eva interlayer, under high temperature(>130℃)& high pressure in an autoclave processed for over 2~6 hours and later form a permanent combination between the glass and the interlayer materials. Laminated glass has a higher strength than a single tempered glass panel. Even if the glass breaks, the broken fragments will still adhere to the pvb or sgp or eva interlayer, completely no harm to human beings. Moreover, laminated glass has an excellent soundproof function. Which makes it popular in an application for crowded places.

Applications of laminated glass: glass roofs, glass curtain walls, glass skylights, glass shopfront, glass floors, other areas.

7, Insulated glass

Insulated glass is also called double glazed glass, it is composed of two or more layers of glass panels separated by an aluminum spacer and sealed with butyl sealant and later structural sealant. Insulated glass is used where good thermal performance and soundproofing functions are required as necessary. Sometimes argon gas will be adopted to enhance the heat & sound isolation performance.

Low-e coating insulated glass can have an extreme energy saving function. In some cold areas or countries, triple insulated low-e glass will be a good choice as the U-value will be lower than 0.6 W/m2K.

Other types of insulated glass such as ceramic frit insulated glass, digital printed insulated glass, PDLC insulated glass, solar reflective insulated glass, etc are all available.

Insulated glass is widely used as curtain wall, windows, doors, partitions, glass walls, etc.

11, Low-e glass

Low-e glass is short for low emissivity glass, is composed of multiple layers of silver, copper or tin or other metals or their compounds on the surface of the glass. The Low-e glass product has a high transmittance for visible light whereas a high reflectivity for infrared rays and good heat insulation performance. Low e glass can help you have a cool environment in the hot summer and a good warm room in the cold winter.

Low e glass shall be applied in insulated glass configuration to prevent its silver layer from oxidizing. The quality of insulated glass is the key to the long lifespan of low e glass.

Generally, there are 3 types of low e glass on the building glass market now: single silver low e glass; double silver low e glass, triple silver low e glass.

For energy saving functions performance are as below:

Single low e glass<double low e glass<triple low e glass;

Low-e glass is mainly used for facade, windows, glass walls, etc.

13, Fire resistant glass

Fire resistant glass is also called fireproof glass. Generally speaking, there are 3 kinds of fire resistant glass:

Single fire resistant glass panel:

The single piece of cesium potassium fireproof glass is ion-exchanged for more than 20 hours at high temperature through special chemical treatment, replacing the metallic sodium on the glass surface to form a chemically tempered stress layer, and after physical treatment, the glass surface forms a high-strength pressure The stress greatly improves the impact strength. When the glass is broken, it shows a state of tiny particles, reducing the harm to the human body! The strength of the single piece of cesium potassium fireproof glass is 6-12 times that of ordinary glass and 1.5-3 times that of tempered glass! Single fire resistant glass panels can be further processed as fire resistant laminated glass, fire resistant insulated glass, etc to enhance soundproofing or energy saving functions.

Composite fire resistant glass:

The production process of traditional composite fireproof glass generally adopts a grouting method, and the expansion flame retardant binder is used between three or more pieces of glass. The layer becomes opaque and plays the role of fire, and heat insulation.

The production process is: firstly cut multiple pieces of glass to the same size, seal them around with a strip, leave a grout, and wait for the bonding between the border and the glass to be firm Afterwards, the fireproof liquid is poured from the grout, after solidification and sealing. This type of fireproof glass has a different fire retardant formula and structure, and the general fireproof time is between 30-90 minutes. Most of the fireproof glass produced by grouting can Meet the three performance indicators of fire integrity, radiation, and heat insulation.

Wired fireproof glass:

Wired glass is a common flat glass produced by the calendering method. When the glass ribbon is formed between the calender rolls, the heated steel wires are placed in the glass plate. Wired fireproof glass can play the role of fire prevention and anti-theft function. When a fire occurs, the wire glass is heated and cracked, but the glass fragments remain on the metal mesh and do not fall off. The whole glass maintains integrity at a certain time. The wired fireproof glass prevents flame penetration and plays a role in preventing the spread of fire.

14, PDLC glass

PDLC glass is also called magic glass, switchable glass, smart glass, intelligent glass, etc. The difference between PDLC glass and ordinary glass is that it can adjust the transparency.

The glass will turn obscure and transparent by only a click of the electricity power.

PDLC glass is widely used in glass partition wall, glass office, toilet glass partitions, windows, facade, etc.

15, Fused glass

Hot-melt glass is produced by setting a specific heating program and annealing curve, after heating above the glass softening point, it will be annealed after special molding and compression molding. If necessary, engraving, drilling, trimming, and other processes will be performed.

17, One-way mirror

One way mirror uses a special coating that can reflect most of the light. It is usually used in the interrogation room or school psychological consultation room or some residential house where privacy is extremely needed. when using a one-way mirror, the reflection surface must be the light-facing surface facing the outdoor. When the outdoor is brighter than the indoor, the one-way mirror glass is similar to the ordinary mirror, and the interior side cannot be seen from outdoors, but the indoor can see the outdoor scene clearly. When the outdoor is darker than the indoor, the outdoor scene can be seen from indoor, and the indoor scene can also be seen outdoor, the degree of clarity depends on the outdoor lightness. The one-way glass is mainly suitable for glass windows, glass walls, etc. This product can be used in special places such as public security bureaus, detention centers, prisons, courts, karaoke, offices, kindergartens, psychiatric hospitals, public toilets, etc.
