Why the Next Breakthrough in Glass Is Thinner
Key Highlights
- Specifying triple pane and impact windows and doors no longer means added bulk and weight.
- New thinner, lightweight window glass is pushing what’s possible in glass performance.
- MITER Brands is leading the charge with two innovative new products made in partnership with leading brands including Corning® and H.B. Fuller.
- Builders can gain significant business advantages with these lightweight, high-performance windows and doors.
Across the industry, there’s a perception that specifying high-performance windows and doors in your builds means dealing with heavier, bulkier products. That can mean significant time and labor costs and added headaches for installation teams. But MITER Brands is challenging that equation with a line of innovative thin glass window and door systems available through its PGT and Sunrise Collection brands.
Instead of just adding more glass to help builders meet rising energy efficiency and impact standards, MITER Brands adds better glass. Specifically, Corning® Enlighten™ Glass, an advanced pane of glass made by Corning Incorporated (the world’s leading innovator in glass and materials science) that is 6x thinner and significantly lighter than traditional soda-lime glass. When combined with the H.B. Fuller Fusion Bonded Spacer System, the result is a line of incredibly high-performance, long-lasting windows that are lighter and easier to install than ever.
Two Category-Leading Products
The Sunrise Collection Advanced Triple Pane leverages a proven window platform augmented with micro-thin Corning® Enlighten™ Glass to deliver a lightweight triple-pane unit that seals out drafts, keeps outside noise at bay, and provides year-round comfort. Builders get windows that are lighter and easier to install, all while delivering the energy performance their customers need to live comfortably, save money on utility bills, and qualify for available energy incentives in select markets.
For Florida and other coastal regions, the new Advanced Impact Glass from PGT delivers the storm protection and quiet comfort of traditional laminated insulated glass in a dramatically lighter unit. Available within the WinGuard® and WinDoor® product lines, windows and doors made with Enlighten™ Glass are nearly half the weight of conventional impact-rated products without sacrificing storm protection and security. Because the lightweight glass layer is located on the interior of the home, it provides up to 3x greater scratch protection over conventional glass; units are code-approved for use in all severe weather code zones, including Miami-Dade County.
These two new innovative products are just the latest evidence of how MITER Brands pushes the boundaries of performance for windows and doors.
Why Builders Should Pay Attention
Lighter glass provides builders the flexibility to meet strict timelines by helping reduce labor hours and speed up installs. Enlighten™ Glass windows from Sunrise and PGT offer superior performance, providing a natural sales path for upgrades that drive margin without the drawbacks of added weight.
Builders who adopt these innovative MITER Brands products in their homes will be better poised to differentiate their business and homes with this unique product, especially in the areas where modern design and rising code standards continue to dominate the conversation.
