To create the energy efficient windows used in homes across the country, Simonton Windows starts with premium vinyl, which has strong thermal properties that help make an excellent insulator. A glass package is then selected to make up the Insulating Glass Unit, otherwise known as an IGU. This occurs when two or more pieces of glass are separated by a spacer system and then hermetically sealed at the glass edges.
Many IGUs are constructed with Low E glass. A transparent metallic oxide coating applied to the glass surface allows short-wave energy to pass through but reflects long-wave infrared energy for greater thermal efficiency.
For added energy efficiency, the space inside the IGU can be filled with Argon gas, a safe, odorless gas that is six times denser than air. This acts as an added barrier for a higher level of efficiency.
Finally, a spacer system can be used in the IGU. Simonton’s top-quality Intercept® Spacer System is made of highly thermally prohibitive materials and placed between the glass panes to further reduce temperature transfer.
The unique U-channel design of this spacer system minimized conduction for increased efficiency and comfort in the home. The U-shaped design flexes and contracts, reducing seal failure in the IGU.
