Premium Laminated Glass Solutions: Safety & Clarity | 5mm, 6.38, 12mm Sheets & Doors
Laminated glass has reshaped architectural glazing and safety standards worldwide. From 5mm laminated glass for residential windows to robust 12mm laminated glass for structural doors, this advanced material is an industry benchmark in modern construction, transportation, and industrial sectors.
Laminated glass consists of two or more glass layers bonded together with a polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) interlayer using heat and pressure. This structure ensures high impact resistance, safety, and superior sound/thermal insulation, making it indispensable across various industries.

Technical FAQ: Laminated Glass Industry Terminology
Q1. What is PVB and why is it used in laminated glass?
PVB (Polyvinyl Butyral) is the primary interlayer due to its superior adhesion, flexibility, and impact energy absorption. It keeps broken glass fragments together after impact, enhancing safety and security compliance per ISO 12543.
