Glazing Options

GS Series windows and doors offer Dura- or TriplePane glazing options for excellent performance in energy efficience, sound reduction, and impact resistance.

DuraPane laminated glass is an innovative glazing system similar to automobile windshield glass, consisting of a plastic safety interlayer placed between two sheets of glass on one of the glass panes of the insulated glass unit.

DuraPane laminated glass has excellent sound reduction properties, making it a great choice for areas with high noise levels.

  • Impact resistant glass panels
  • STC ratings using DuraPane can reach levels up to 34-36 (Individual product ratings may vary due to window size and glass options)

TriplePane Glass
Our triple pane insulated glass unit consists of three layers of glass sealed with Duralite spacers. Inner glass chambers are filled with argon gas.

Along with better home insulation, a triple pane window is among the very best choices for an energy efficient home. Stop energy from escaping through inefficient windows, upgrade to new GS Series windows today!

  • 2 LoE3 glass panes for maximum energy savings
