For ultimate safety glass for earthmoving, mining and heavy plant machinery Service 8 now supplies fortress glass. Fortress glass is should be used where the chance of cab intrusion is a high risk.
Test have shown Fortress Glass is superior in strength and durability over existing laminated glass in the market. The safety of machine operators is increased by its strength, as well as reducing operator fatigue, due to the reduction in solar heat gain and noise attenuation properties. Make no mistake Fortress Glass can save lives
Safety - Intrusion and impact resistance
The following tests were performed in accordance with AS/NZS 2080 appendix-I, using a 2.25kg hardened steel ball dropped from heights listed in the table below. Test area temperature was 35°C ± 2°.

Productivity - Less incidental breakage
With the added combination of PET and PVB interlayers, incidental breakage (chips and cracks) are reduced, minimising machine downtime and improving machine and worker productivity.
Thermal Comfort - Heat and radiation shielding
Fortress Glass 72-41 laminated glass was developed to reflect 99% of ultraviolet and 94% infra-red radiation, thereby reducing solar heat gain by over 55%. A cooler and more comfortable work environment with a reduction in thermal skin sensation will minimise operator fatigue and increase safety and productivity.
Noise Attenuation - Easy on the ears
The acoustic properties of noise dampining PVB plus heat reflective PET interlayer film greatly diminishes the transmission of high frequency noise by 8 decibels and low frequency noise by around 5 decibels. The operator benefits from improved acoustic comfort and increased hearing safety levels.
Visual Clarity & Low Reflectivity - Unmatched in night work applications
Unlike conventional tinted films and glass, Fortress Glass is transparent and has a low reflectivity so you are never forced, day or night, to sacrifice clarity and light transmission. A safer and more productive workplace is achieved as nightime visibility is maximised while internal reflectivity of cabin lights is minimised.
