Stay Safe 
This Season

Laminated glass in an impact-resistant window is comprised of two panes of glass bonded together with a transparent, shatter-resistant interlayer. This configuration enhances the structural integrity of the glass. Even in the event the glass does break, the inner layer keeps it safely in place. In addition to protection against break-ins and storm-driven debris, the layering provides sound attenuation. 

The interlayer, a crucial component of laminated glass, consists of a transparent, shatter-resistant membrane of polyvinyl butyral (PVB) or SentryGlas (SG). This layer is designed to flex without breaking, preventing shattering and penetration, and ensuring that even if the glass cracks, your home stays sealed from the elements. While the glass can break when struck, the interlayer keeps broken glass in place and prevents it from becoming a hazard. Beyond its toughness, the interlayer is a guardian against ultraviolet rays, reducing the sun’s ability to fade your furniture and decor.

The Thermoplastic Spacer (TPS) system is integral to the window’s insulating capabilities, keeping them fog-free and energy-efficient. The innovative system establishes an airtight and moisture-resistant seal that enhances the overall thermal insulation of the window assembly, prevents condensation between the glass panels, and maintains the air or gas-filled space between the panes.

The insulating air space is situated between the laminated glass pane and the outer glass pane, where it creates a thermal and acoustic buffer. The space acts as a buffer, slowing down heat transfer and muffling noise. This thermal barrier is fundamental in reducing the U-factor of the window, a measure of its insulation performance that contributes to a stable interior environment. An option to incorporate inert argon gas within this space increases the window’s ability to inhibit heat transfer.

The UV Performance Coating applied to the glass surface is engineered to reduce solar heat gain while maintaining high levels of visible light transmittance. The coating operates on a molecular level to reflect long-wave infrared energy, contributing to the window’s thermal efficiency. The reduction of UV and infrared light penetration not only decreases energy costs associated with cooling but also protects against the detrimental effects of UV exposure on interior fabrics and finishes. 

The outside pane of PGT windows does more than just offer a clear view of your neighborhood, it is also the first line of defense. It’s the first layer in a suite of technologies designed to keep your home secure, insulated, and energy-efficient. This single pane of glass enhances the window’s overall insulating properties, ensuring that your home stays warmer in the winter and cooler in the summer, all while maintaining the crisp, clear sightlines you love.

PGT® WinGuard® Vinyl windows and doors feature a multi-chambered frame and warm-edge spacer technology to increase energy efficiency. Exclusive to vinyl, these custom-built frames are made of 100% virgin uPVC* vinyl, which contains micro ingredients that enhance heat and color stability. For ultimate climate control at the height of summer or the dead of winter, PGT® WinGuard® Vinyl windows and doors are the only choice you need to make. Unlike wood sashes and frames that split, rot, and require regular painting, vinyl frames are virtually maintenance-free and highly resistant to the environmental factors that limit the life of wooden frames.
