HAMMERGLASS

What is Hammerglass®?

Hammerglass® is a durable and optically clear polycarbonate sheet that is 300 times stronger than glass - and virtually unbreakable. Hammerglass panels are coated with a hard silicon oxide layer that protects against scratches and abrasion. The surface coating also provides 99.96 per cent UV protection, which prevents Hammerglass lenses from becoming cloudy or discoloured over time. Hammerglass does not contribute to the spread of flames in the event of a fire.

How good is the optical quality of Hammerglass®?

A 12-millimetre hammerglass window has the same high optical quality as windows in helicopters and aeroplanes.

How high is the heat reduction with Hammerglass IR?

Hammerglass IR (Infra Red) removes 45-55 % of the incident solar heat.

How to get rid of static electricity?

Static electricity on Hammerglass windows disappears when the windows are washed with water and a little rinse aid (normal washing machine rinse aid).

How to order Hammerglass?

Sales are made through resellers, our webshop or directly through Hammerglass AB. We are happy to answer questions and actively participate in the product development of new solutions.

RABS

What does RABS mean?

RABS are abbreviations for the European standards

  •     R43 (UN ECE R43)
  •     AXE (EN 356 P8B)
  •     BLAST (EN 13123-2 EXR2)
  •     STONE (EN 15152-2, 450 km/h)

The RABS marking for vehicle shields means that the shields meet the requirements for personal protection during work where there is a risk of coming into contact with non-detonated explosives and falling rocks, and during quarry work.

What is Hammerglass RABS?

Hammerglass RABS is an explosive protection for excavators and wheel loaders, consisting of 12 mm thick hammerglass in a sturdy RABS approved steel frame and a replaceable 4 mm thick sacrificial grid.

Does Hammerglass RABS offer the same protection as metal windscreen protectors?

The RABS frame has been tested and approved in the same way as cabin guards (FOPS test ISO EN 3449:2005 level II). There is no need for additional grilles, even in the harshest environments.

Does Hammerglass RABS work with windscreen wipers?

Longer original windscreen wipers combine well with Hammerglass RABS. For machines with a short original windscreen wiper, the RABS frame has been equipped with a special wiper package from Hammerglass.

WINDOW PROTECTION PANE & WINDOW PROTECTION FILM

What is the Hammerglass ScreenSaver protective screen?

The Hammerglass ScreenSaver protective screen made of 4 mm Hammerglass protects the sturdier 12 mm Hammerglass screen in the RABS frame from damage caused by stone splinters, etc. The ScreenSaver screen is attached to the RABS frame with a clamping frame and is easily replaceable. The ScreenSaver screen is a pure wear product.

How is condensation avoided when changing the Hammerglass ScreenSaver protective screen?

When changing the ScreenSaver protective screen, the absorbent strip must also be replaced. If this is not done, there is a risk of condensation because the air trapped between the screens contains moisture.

What is the Hammerglass ScreenSaver protective film?

The ScreenSaver protective film is a self-healing scratch protection film that can be applied to the Hammerglass windscreen to protect it from wear and tear caused by windscreen wipers in sandy environments. The ScreenSaver film extends the life of the Hammerglass windscreen. When the film wears out, it can be easily replaced with a new film.

Does the Hammerglass ScreenSaver film work when hammering on rocks?

A ScreenSaver film will not work when hammering stones. The stone splinters will punch holes in the film and small water-filled bubbles will form inside the ScreenSaver film. For hammering stones, we recommend a RABS frame with Hammerglass and a ScreenSaver protective film.
