Laminated glass is made using two or more lites of glass that are joined under high heat and pressure on either side of a clear or tinted interlayer to form a single piece of glass. Its primary benefit is that, if broken, the glass adheres to the interlayer and will not vacate the opening. In addition to the safety glazing benefits, laminated glass also reduces the level of sound transmitted and damaging ultraviolet light that fades furnishings and artwork. It can be combined with many other glass types for a wide range of benefits.

Applications: Curtain walls, doors, flooring, glass railing, skylights, sound control rooms and other applications that require safety, security, hurricane impact, sound control, detention, seismic-resistant, blast-resistant, bullet-resistant and forced entry protection. Specific applications may require different types of interlayer material, configurations, testing and approvals.

HURRICANE IMPACT LAMINATED

Impact laminated glass is specially fabricated to remain its integrity in the framed opening following an impact from windborne debris and wind cycling. This protective glazing features two or more glass lites laminated with a .090” polyvinyl butyral (PVB) interlayer to achieve standards for large missile protection, or a .060” PVB interlayer for small missile protection. Sentry Glas® interlayers are also available.

Impact glass used in hurricane prone areas must be in compliance with the Florida Building Code requirements and ASTM E1996—proven to stay within its frame after impact from either a 9-pound 2 by 4 traveling at 50 feet per second (large missile) or 10 ball bearings traveling at speeds of 80 feet per second (small missile), plus 9,000 cycles of positive and negative wind loads.
