Energy Efficiency & Comfort

  • Available Low-E glass packages with warm edge spacers help keep cooled air inside your home in summer and more warm air inside during winter for year-round comfort.
  • For increased thermal efficiency, choose a High Performance HP glass package with Argon gas which is six times denser than air and sealed in the insulating glass unit.
  • HP Glass Packages with specialty Low-E glass and Argon can greatly reduce solar heat gain and lower cooling costs in warmer regions.
  • Ply Gem 550 windows can be ordered ENERGY STAR® certified wherever you live to help keep your home comfortable while protecting the environment.

  • Give noisy neighborhoods and busy streets the silent treatment with acoustic glass packages available in the 550 series. By preventing sound vibrations from passing through the glass, acoustic and laminated glass can reduce unwanted noise by up to 50%.

Fade Protection

  • Reduce fading of your furnishings, window treatments and flooring with optional Low-E or laminated glass that helps filter out the sun’s harmful ultraviolet rays.

Increased Privacy
