Laminated

Upgrade your high performance glass package with Laminated Security Glass.

Our fully automated, in-house laminated glass line is designed for strength, safety, and comfort. It reduces noise, blocks UV rays, and protects against intruders—all while enhancing your living space. Made from two or more glass layers bonded with SentryGlas, PVB, or EVA, laminated glass is a trusted choice wherever safety matters most.

Tempered

Upgrade your high performance glass package with Tempered Safety Glass.

At Window City, we manufacture tempered glass with safety in mind. As a trusted form of safety glass, it undergoes thermal treatment to increase strength and durability. Four times stronger than standard glass, it shatters into small, dull fragments to reduce injury. With exceptional heat resistance, tempered glass is a required choice for many safety-critical applications.

Laminated & Tempered

Upgrade your high performance glass package with Tempered & Laminated Glass.

Our fully automated, in-house tempering and laminating lines allows us to offer the sealed units combined with the benefits of both glass types, offering superior strength, safety, and sound insulation compared to standard glass; tempered glass provides high impact resistance while the laminated layer adds further security by holding the shattered pieces together upon impact, making it ideal for applications where safety is paramount, like storefront windows or entry doors.
