Clear armour laminates offer increased protection against explosions and gunfire

Paul Boughton

These laminates are targeted at applications ranging from buildings, guardhouses, armoured vehicles and detention centres, to schools, banks and critical infrastructure such as power plants, government buildings, and embassies. They deliver exceptional heat and impact resistance, along with outstanding energy absorption, low weight, and anti-spall (the spray of glass fragments) properties.
These GE glazing products meet widely recognised standards – such as ASTM, UL, HP White, NIJ, and European standards EN356, DIN52290 Part 3, EN1063, and DIN52290 Part 2 – and may provide protection against many of the overpressures and fragments associated with explosions. They have been tested to absorb up to 393kPa (57psi) – which is the equivalent of 1950kg (4300lb) of TNT detonated from 35m (115feet) away – and may withstand gunfire from weapons ranging from 9mm handguns to 7.62mm NATO high-powered rifles.
GE’s Armorgard laminated glass and PC sheet grades may help provide a highly effective barrier against a variety of ballistic assaults without spalling on the protected interior surface. They meet the full requirements of UL752 up to Level 8 and are available in no-spall and low spall designs. No-spall designs feature an exterior glass (threat side) surface with a Margard sheet interior (safe side) surface for increased UV and mar resistance, while the low-spall version provides glass on both interior and exterior surfaces and are designed to help stop bullet penetration.
Designed to help withstand impact from implements ranging from hammers and axes to propane torches and fire extinguishers, GE’s Suregard glass-clad PC laminate is targeted primarily at protection against smash-and-grab raids.
