Ballistic Glass

Constructed from several layers of glass bonded with various interlayers of tough polyvinyl butyral (PVB), polyurethane and polycarbonate. The construction of the glass is designed to absorb and disperse the impact energy of a projectile, safeguarding those behind the glass.

Spall Allowed vs No Spall

Sarkar offer two fundamental options for bullet resistant glass; spall allowed and no spall. The requirement for spall allowed / no spall is part of the European standard BS EN 1063. Both options are very effective but are suited to different applications. Spall allowed will emit splinters of glass from the reverse of the panel when impacted. It makes it suitable for applications with a stand-off distance from the glass, e.g. a shop window, or similar.

No spall is constructed using both glass and polycarbonate one of the strongest glazing materials available with an impact resistance many times greatest than float or toughened glass. The polycarbonate fully absorbs the impact of the projectile resulting in a zero spall option which provides superior bullet resistance, enabling overall glass thickness to be reduced by up to 40% over conventional bullet resistant glass; enhancing light transmission and glass clarity. No spall could also be achieved with an antispall film, No spall constructions are particularly suited to applications such as cashier booths and vehicles; anywhere where people will be positioned within a close proximity of the glass.
