The space inside an insulating glass unit—between the glass panes—may be filled with Argon gas, an odorless, non-toxic gas that is six times denser than air. This acts as an added barrier for a higher level of efficiency. Available in some regions of the country, Krypton gas is even denser than Argon gas and further maximizes energy efficiency and temperature transfer
Most Simonton windows and doors feature unique spacer systems. Made of highly thermally prohibitive materials, these are placed between the glass panes and further reduce temperature transfer.
Simonton vinyl replacement windows are custom manufactured and installed, quickly and conveniently. Product styles include: slider, awning, bay, bow, casement, double hung, fixed, garden, geometric, picture, single hung, single slider and transom.
