Annealed glass

Annealed glass, commonly known as the standard glass, undergoes a thermal treatment process followed by slow cooling to eliminate internal stresses. It is commonly utilized in applications where safety considerations are not a primary concern.

Fully tempered glass

Fully tempered glass is significantly stronger than annealed glass, with a strength four times greater. In the event of breakage, it shatters into small, safe pieces, minimizing the risk of injury.

Heat Treated Glass

Heat-strengthened glass undergoes a slower cooling process compared to tempered glass, resulting in a lower compression strength. However, it still provides approximately twice the strength of annealed glass.

Laminated Glass

Laminated glass can withstand strong impacts. It is a superior solution to safety glazing.

Laminated glass does more: it is the type of safety glazing that also remains intact within the window frame.


Neat Glass

Unlike regular exterior window surfaces, Neat glass requires minimal maintenance. With Neat technology, the glass stays cleaner for longer periods. And when the time comes to clean, you'll find it quick and effortless.
