Energy Efficiency and the Environment

energy_efficiency_2Our products and processes emphasize energy savings – and that means we consume less energy to minimize the CO2 released into our environment.

Our buildings save energy by utilizing in-floor radiant heating during off-peak energy hours and by using motion controlled lighting.

Our processes conserve resources – like filtering and reusing glass wash water for glass rinsing, and recycling our vinyl and glass scrap created during the fabrication process. And of course, we have a recycling program for metals, cardboard and paper.

Interstate belongs to a voluntary energy cooperative that monitors and helps reduce energy usage during times of peak demand. We are helping to protect our community from blackouts, to keep energy rates stable and to help the environment by reducing reliance on peaking power plants.

Our business focus stays within 250 miles of our production facility to minimize transportation energy.

And lastly, we had implemented many of these conservation measures decades before the term “green” became popular. At Interstate, energy efficiency and environmental concerns have been a way of life for generations.

  • Double Pane with Truseal’s Duralite™ or Duraseal™ Spacer
  • 3/4” to 7/8” insulated assembly with ClimaGuard Soft Coat Low E glass and Argon gas in the chamber
  • U-factor: .30 – 4000, 4200 Double Hung

Low E is a transparent metallic oxide coating applied onto a glass surface. The coating allows short-wave energy to pass through but reflects long-wave infrared energy, which lowers the U-value and that means more energy savings. An odorless, colorless, tasteless, non-toxic gas, argon is six times denser than air. It is used to replace air between the glass panes to reduce thermal energy transfer and heat loss.

ClimaGuard glass has heat reflective coatings – microscopically thin layers of metal and metal oxide that filter energy by keeping warmth inside in winter and outside in summer.





A patented radiant glass technology that produces thermal energy, R-Series technology provides transparent insulation by creating a perfect thermal barrier between the building envelope and the exterior environment, and can also be used as a primary or auxiliary heat source.

  • R-value: Measures a product’s resistance to heat loss. Materials with higher R-values are more energy efficient. R-5 rated windows have an R-value of 4.51 to 5.00 and above.
  • U Factor: Measures how well a window prevents heat from escaping. The lower the U Value, the better the window is at keeping heat in and the more efficient it is.
  • Overall insulated glass thickness ranges from 3/4” to 1”.

Built Tough Hardware

All GreenView vinyl windows come standard with the industry’s finest hardware system. The operators, locks, and hinges have all been developed to work together to meet or exceed maximum performance requirements. Interstate provides the strongest, most attractive, easiest operating and highest performing hardware in today’s market.




Grids bring a distinctive look to your home. Four grid styles in a variety of color and style combinations offer many choices when selecting grids for your windows. Grids Between Glass (GBG) afford easy cleaning, Applied Surface Grids (ASGs) are permanently adhered to the panes inside and out and are designed to look like a true multi-paned window.
