Windows for Tomorrow

As a company, we embrace many environmentally friendly manufacturing practices. We recycle a variety of industrial and shipping materials, and use resources in close proximity to our facilities to lessen the amount of fuel used in transportation.

Because efficient environmental stewardship demands cooperation among the government, architects, manufacturers, builders and consumers, Ply Gem Windows works with a number of agencies and initiatives, like the United States Green Building Council (USGBC), the National Association of Home Builders (NAHB) and ENERGY STAR® to achieve “green” results for both the commercial and residential markets.

Green is more than a color at Ply Gem Windows – it’s the way we do business. We’re leading the way with environmentally friendly windows that are sealed and insulated so well, they help lower utility consumption. But we aren’t stopping there. We want to make sure we also reduce our company’s carbon footprint by operating our business in the most energy efficient manner possible.

Our Sustainability 
Efforts Are Clear

  • Our windows insulate better because they feature high performance spacer systems and advanced window frame designs.
  • Special Low-E glass coatings help windows reflect infrared light, keeping homes comfortable in extreme heat and cold.
  • Our products can use multiple Low-E coatings, specifically tailored to the needs of different climate zones.
  • Our multiple pane options offer greater energy efficiency, increased impact resistance and better sound insulation.
  • Gas fills such as argon and krypton provide better insulation than regular air.
  • The creative use of materials and pre-finished wood parts results in reduced on-site finishing and less on-going maintenance.
  • Select Ply Gem products sold in Canada are registered for use in the Canadian Built Green program. For details visit
