Our premium vinyl is an excellent insulator that reduces heat transfer and insulates against temperature changes.
Dual-pane windows create a sealed insulating glass unit that offers superior insulation compared to single-pane windows. Triple-pane glass provides even greater energy efficiency, insulation and sound reduction.
ProSolar® Low-E glass helps keep warm air in during winter months. In summer, it helps deflect external heat, retains cooled air and blocks damaging ultraviolet rays.
Argon gas is sealed between the glass panes. This odorless, non-toxic gas is much denser than air, so it insulates better.
Low-conductance spacer systems seal the glass panes to create an airtight unit that increases insulation and minimizes heat transfer through the window or door.
Three panes of double-strength glass create two separate air spaces for maximum insulation, consistent interior temperature and energy savings.
The American Architectural Manufacturers Association (AAMA) Gold Label means your window and door have been manufactured and tested to the highest quality standards of one of the toughest certification programs in the industry.
Windows must meet an air leakage standard of 0.30 cubic feet per minute or lower at wind speeds of 25 miles per hour.
Water infiltration is tested by applying water to the surface of the sample window or door at a rate of five gallons per hour per square foot, exceeding any rainfall rate ever measured in a natural storm.
Simonton windows and doors are sold through our large network of trusted contractors, retail stores and distributor locations.
