Glass Options

When it comes to saving energy and keeping your home more comfortable, you need the right glass package to get the job done. Simonton Windows^® combines the most effective features and the most advanced designs to achieve truly impressive year-round thermal performance. 

Standard Glass Package The standard glass package on most windows comprises ProSolar™ soft coat Low E glass, an Argon gas fill, the Intercept^® spacer system and a deep-set insulating glass unit.

In summer months, Low E glass keeps cool air inside while keeping hot air outside. In winter, Low E glass keeps warm air in and cold air out. Low E glass also blocks 84% of UV rays which can fade carpets, draperies and artwork.

1” I.G. and Super Spacer^® This upgrade combines double-strength ProSolar™ soft coat Low E glass, an Argon gas fill, the Super Spacer^® solid silicone foam spacer and a 1” insulating glass unit.

Krypton Gas Fill Available on select series, this optional upgrade increases efficiency by replacing air in the insulating glass unit with Krypton gas. Nearly 12 times the density of air, Krypton gas provides superior insulation.  

Laminated Glass For the ultimate in efficiency and security, choose laminated glass. This remarkable glass blocks over 99% of the sun's most damaging UV rays. For added safety, the laminated glass will not fall out inside the home if the window is struck with force and also helps reduce noise transmission.
