Did you know?

On average, Americans pay between about $1,500 and $2,500 annually on energy bills. Heating and cooling are responsible for up to 45% of that cost.* With WinGuard® impact resistant windows and doors, there are many options to maximize the energy performance. Additions like high-performance low-E coatings, glass tints, and argon glass can help you achieve ENERGY STAR® ratings and potentially save money. One recent study found that after installing impact resistant windows, monthly energy bills were reduced by a median average of over 12%.**

Best Performing Laminated Insulating Glass

Laminated hurricane impact-resistant glass, “the sandwich”, is comprised of two panes of glass bonded together with a protective interlayer to form an incredibly strong glass unit that functions as a single pane. “The sandwich” is the primary barrier used in impact-resistant windows and doors during extreme weather events or to deter potential intruders.

Laminated Insulating glass adds an extra single pane of glass to the laminated glass unit with a sealed air or argon filled space in between to help reflect outside heat, so indoor temperatures fluctuate less. This offers greatly enhanced energy performance.

PGT’s laminated insulating glass has ZERO reported seal failures for over 5 years, compared to to an industry average of 2% yearly failure rate.

Enhanced for energy efficiency

WinGuard® windows and doors offer enhanced levels of energy efficiency with the following options:


Deflects the heat of the sun to boost energy savings while keeping your indoor climate more comfortable.


Available in a range of shades to reduce heat transmitted through windows and doors even in the sunniest regions.

Gray and bronze tints reduce the penetration of light and heat into your home.

Blue and green tints provide greater penetration of visible light, slightly reducing heat transfer compared to other tint shades.


Helps reflect outside heat, so indoor temperatures fluctuate less.
