MITER Brands Expands Triton™ Advanced Glass Systems with Triton™ Advanced Impact Glass for PGT® WinGuard® Vinyl Products

Key Terms

laminated insulating glass units technical

A laminated insulating glass unit is a multi-pane window assembly that sandwiches a thin, plastic interlayer between two or more glass panes and seals them together to form an insulated, single unit. Think of it like a glass sandwich where the plastic layer keeps shards bonded if broken and the space between panes reduces heat transfer; it also improves sound insulation and blocks some UV. Investors care because these units affect building energy performance, safety, compliance, maintenance costs and demand in construction and retrofit markets.

thermal conductivity technical

Thermal conductivity is a physical property that measures how quickly heat passes through a material; think of it as how fast a metal spoon becomes hot when left in hot soup versus a wooden spoon that stays cool. Investors care because it affects product performance, energy efficiency, manufacturing costs and safety—factors that influence operating expenses, market competitiveness and long-term durability of materials used in industries like electronics, construction, automotive and energy.

interlayer technical

A thin material layer placed between two other layers in a manufactured product to perform a specific role such as bonding, electrical insulation, chemical barrier, stress relief, or charge transport. Think of it like a sandwich filling that helps the outer slices stick together, keep things separate, or change how the sandwich behaves; in technology products it can affect performance, durability, manufacturing yield and cost. Investors watch interlayers because their design and quality can influence product reliability, production efficiency and competitive differentiation in materials and devices.

HARRISBURG, Pa.--(BUSINESS WIRE)-- MITER Brands, a family of leading window and door brands, recently announced the expansion of its Triton™ Advanced Glass Systems portfolio, adding Triton™ Advanced Impact Glass to the full line of PGT^® Windows and Doors WinGuard^® Vinyl products. Engineered to deliver the uncompromising storm protection of traditional impact windows, Triton Advanced Impact, featuring Corning^® Enlighten™ Glass, offers reduced weight for ease of operation and installation, noise reduction, enhanced clarity, improved durability, and year-round comfort.

Triton Advanced Impact meets Miami-Dade testing standards in glass units up to 40% lighter than traditional glass.

“The PGT team is excited to offer our WinGuard Vinyl products with innovative Triton Advanced Impact Glass,” said Steven Starkey, Vice President of Sales, MITER Brands-South. “Perfect for Florida and the other coastal regions for which our WinGuard Vinyl product line is designed, this advancement in glass technology moves the industry forward by delivering the storm protection of traditional impact windows and doors in a significantly lighter package, expanding what’s possible for impact-rated construction and replacement projects.”

Triton Advanced Impact Glass features MITER Brands’ proprietary Triton Glass Sandwich™, which bonds micro-thin Corning Enlighten Glass to a flexible, shatter-resistant interlayer, creating a single lightweight, exceptionally strong pane of glass. The interlayer also helps to reduce outside noise for a more comfortable indoor environment.

Laminated insulating glass units are further enhanced by the long-lasting H.B. Fuller^® 4SG^® Fusion Bonded Spacer, which creates an energy-efficient air barrier that minimizes heat transfer and resists moisture penetration to reduce fogging. These two innovations, combined with the low thermal conductivity of the product line’s vinyl frames, create unprecedented strength and energy performance.

Designed to meet the stringent Miami-Dade testing standards for the highest level of hurricane protection, Triton Advanced Impact delivers impact-rated performance in glass units that are up to 40% lighter than traditional impact windows*, improving usability and ease of installation. Its reduced weight also provides meaningful advantages for replacement and remodeling projects, requiring less labor to upgrade homes, multifamily buildings, and commercial properties to impact-rated windows and doors without significantly increasing the weight of the overall glazing system.

With PGT WinGuard Vinyl products featuring Triton Advanced Impact glass, homeowners benefit from improved year-round energy performance, reduced outside noise for a more comfortable indoor environment, three times greater indoor scratch resistance, and exceptional clarity with virtually zero visual distortion.
