Hammerglass is the new generation of high performance glass in nano surface-treated polycarbonate. A durable and wear-resistant polycarbonate sheet, 300 times stronger than glass and virtually unbreakable. Hammerglass screens are coated with a thin film of silicon oxide, which protects against scratches and wear and tear. Nanotechnological surface treatment renders Hammerglass resistant to most chemicals - which enables simple graffiti removal, and helps to prevent pollutants from exhaust fumes, oil and asphalt from adhering to Hammerglass as easily as to ordinary glass. The surface treatment also provides 99.96% UV protection, which means the material will not cloud, discolour or undergo any other change in optical quality over time. Hammerglass does not contribute to the spreading of flames in the event of fire. With its array of positive features, and half the weight of conventional glass, Hammerglass is an excellent choice both for new installation and glass replacement.

RABS is the designation for vehicle screens which indicates that the screens satisfy a combination of international safety standards. In order to be marked "RABS Approved", the screens must pass all of the following four tests. Using a RABS-classified solution satisfies personal protection requirements for work involving the risk of undetonated explosives, falling rocks and while quarrying. Hammerglass in a steel frame satisfies the RABS requirements.

The level of safety required depends on the type of activity involved. Normally, Protection Class 1 is more than sufficient. This corresponds to 8 mm Hammerglass in the windscreen in order to eliminate the risk of breaking glass. If the machine is being used in very tough environments where there is a risk of stones being propelled at high speed, or of explosions, then thicker RABS approved screens will be required all around the cab. Our classifications will help you find the proper protection for work in tough environments.

PROTECTION CLASS 1
For simpler tasks where there is a risk of stone chippings. Usually required for the windscreen and/or side screen on diggers, wheel loaders, tractors, etc. The original screen is replaced with 8 mm Hammerglass, which is fitted in the same way as the original screen.
Front window: 8 mm Hammerglass, split/non-split
Boom side window: 8 mm Hammerglass
Accessory: ScreenSaver protective film for the front window

PROTECTION CLASS 2
For tough driver environments where there is a risk of stone chippings, falling stones, and acts of vandalism. The original screens are replaced with 8 mm/12 mm Hammerglass screens, which are fitted in the same way as the original screens.
Front window: 8 mm/12 mm Hammerglass, split/non-split
Other screens: 8 mm/12 mm Hammerglass
Accessory: ScreenSaver protective film for the front window

PROTECTION CLASS 3
Where there is a risk of undetonated explosives, where quarrying is being carried out or there is a risk of rock fall. The cabin has to offer an escape exit via an escape screen. This has to be reachable by the driver in case of rock slides which close off all other exits. The escape exit also has to be openable from the outside.
Front window: 12 mm Hammerglass an explosion tested steel frame, RABS approved
Other screens: 12 mm Hammerglass
