Energy Efficiency

Simonton Grand Room Windows
Simonton Windows understands that energy efficiency is more important than ever.  That's why they are continuously looking for ways to make their windows and doors as thermally efficient as possible.  From the materials they use to the glass packages they offer, their dedication as an ENERGY STAR partner is quite apparent.

Premium Vinyl

The premium vinyl used in Simonton Windows is an excellent insulator.  Its thermal properties are far superior to aluminum, steel and stainless steel.

Spacer Systems

Most Simonton Windows feature unique spacer systems.  Made of highly thermally prohibitive materials, these are placed between the glass panes and further reduce temperature transfer. 

Intercept Spacer System

Simonton Intercept Spacers

  • Unique U-Channel design minimizes conduction for increased efficiency and comfort
  • Durable long-lasting design
  • U-shaped design flexes and contracts, reducing seal failure in the insulating glass unit

Super Spacer System

Simonton Super Spacer System
  • Solid silicone foam provides superior energy efficiency
  • Does not conduct energy as quickly as metal spacers
  • Silicone foam is flexible and helps reduce stress cracks

 Glass Coatings

Many Simonton Windows are available 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.  

Gas Fill

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. 

Laminated Glass

Some glass packages contain laminated glass.  A transparent interlayer is adhered to a pane of glass, acting as a barrier against energy loss, noise transmission and forced entry.

From Our Customers

I was able to customize my order with FAS Exteriors and a lot of the options presented to me met our needs. The sales team member who came here was very good and knew what he was talking about. I got to the bottom-line, which is what we were looking for. Also, the installation team has been very good. They cleaned up after themselves and did the job in a very expeditious manner. So far, the door's quality is good and overall, it was a pleasant experience. They told us what we would receive and they delivered what they told us. Everything went well with FAS Exteriors.
