Glass Options

Choosing the right glass options for your Classic Series windows can make your home more comfortable and reduce energy costs as well as increase security, privacy and fade protection.

Low-E Glass and High-Performance Glass Packages
  • Optional Low-E glass packages help deflect summer heat to keep your home cooler and retain warmed air inside during colder months.
  • Choose a High Performance HP glass package with Argon gas, which is six times denser than air and placed in the insulating glass unit for additional protection from energy loss.
  • HP Glass Packages with specialty Low-E glass and Argon can greatly reduce solar heat gain and lower cooling costs in warmer regions.
  • The Warm Edge spacer system features a U-shaped channel that separates the glass panes and interrupts the natural flow of heat to cold. It also flexes when the glass expands and contracts to help maintain a strong seal.
  • Optional Warm Edge+ spacer systems are made of less-conductive materials for increased energy performance and added strength to better resist seal failure.
