5 Property Comparison for PC Polycarbonate Sheet Vs Glass

PC polycarbonate sheet and glass are both common lighting building materials on the market today.

PC sheet and glass each have their own advantages and disadvantages

1. Weight

The weight of PC Sheet is about 1/3 of the glass of the same specification, and the price is about 2-3 times.

For example, if the PC Sheet has a thickness of 4.5mm, you can buy a glass thickness of about 10mm at the same price.

PC Sheet is lighter in weight than glass, and its bendability makes it suitable for small spaces and special angles.

It can be used in various spaces and facilitates construction. With the same thickness, the sound insulation effect of PC Sheet at high frequencies is better than that of glass.

2. Safe

Glass also has special functional glass such as tempered glass, and the risk of glass construction is much lower than before.

However, even tempered glass has the risk of the entire piece of glass shattering in strong winds and earthquakes. Even special glass can be broken. Will still cause harm if cracked.

On the contrary, PC Sheet does not have this problem.

The strength of PC sheet is 250 times that of ordinary glass and 50-100 times stronger than tempered glass.

PC sheet has strong toughness and will not break even if it is hit with a hammer.

The acceptable impact strength per unit area is 91kgf-cm/cm, and the compressive strength is 739kgf/cm^2.

It is an excellent building material for areas with frequent earthquakes and strong winds.

3. Weather Resistance and Durability

When glass is used as a building material, two thin pieces of glass are often combined into one piece of thicker glass by gluing.

The glass may become brittle after being exposed to the sun for a long time, causing safety issues.

Since ordinary people often have the concept of weather resistance and durability of glass, they do not have a deep understanding of the problem that glass may break after being exposed to the sun for a long time.

Taking coastal areas as an example, it is easier to withstand the windward side of typhoons, and buildings are exposed to stronger winds, so glass is less used as a building material during construction.

4. Price

Because the cheap PC sheet in the market often use recycled materials to reduce production costs and lower selling prices to compete.

The method, which ignores quality, makes ordinary people have the impression that PC sheets are prone to yellowing and are not durable. However, PC sheets produced with high-quality new raw materials from us in China are guaranteed to last for more than 10 years.

5. Thermal Expansion Coefficient

Compared with glass, PC sheet has a larger thermal expansion coefficient, which is about three to six times that of glass.

Although glass is easier to break, its hardness is also higher than PC sheet, and it is less likely to be scratched during transportation.

Compared with PC sheet, problems such as fogging caused by scratches and scratches have their own advantages and disadvantages.

Glass with a finer surface is less likely to absorb dust. General PC sheet on the market have larger pores, which can easily cause the PC sheet to feel dirty after absorbing dust.

Only high-quality sheets such as our PC UV sheets are relatively fine and will not have this problem.
