Choosing Vinyl

Increased Comfort
Simonton’s vinyl windows and doors offer excellent thermal performance for year-round comfort and to help lower utility bills.
Easy Operation Our windows and doors open and close easily for maximum performance with minimum effort.

The premium vinyl used in Simonton windows and doors can stand up to extreme weather conditions year after year.

Energy Efficiency
Vinyl is an effective insulator. Our vinyl profiles are specially designed to work with advanced glass packages for optimum energy efficiency.

Low Maintenance
The color of the vinyl is integrated throughout, so frames and sash will never require painting, and they resist pollution, salt spray and dirt.

Not only do Simonton windows and doors help to lower home utility bills, they also add value to your home.

Tips for Deciding When to Replace Windows

Looking for tips to help evaluate the effectiveness of windows and doors in a home you’re going to purchase, or just want to see if it’s time to replace your windows? Try these for starters:

  1. Determine how many panes of glass are in the windows. Single-paned windows are the least energy efficient. You can replace them with double- or triple-paned ENERGY STAR® compliant windows to enhance energy efficiency and make a home more comfortable during all seasons.
  2. Look for condensation inside the glass on double- or triple-glazed windows. This could indicate seal failure. If this is the case, you might need to replace the glass or the entire window.
  3. Do your windows open and close easily? If your windows are hard to open or close—or they won’t stay open or locked—this could be a sign that the windows need replacing.
  4. Have someone stand outside your window. With a small flashlight, stand inside and “travel” around the window’s perimeter. If the person outside sees areas of light coming through, this is an indication of seal failure—and probably energy loss.
  5. Does it seems especially noisy in your house? If you live near an airport or busy street, consider replacing your windows with laminated glass windows to help reduce noise transmission.
  6. Did your neighbors just build a new home that’s too close to your bathroom? For added privacy, request decorative obscure glass in your windows. This will allow light to flow into the home, but will keep your privacy!

Energy Efficiency

At Simonton, we understand that energy efficiency is more important than ever. That’s why we are continuously looking for ways to make our windows and doors as thermally efficient as possible. From the materials we use and the glass packages we offer to our dedication as an ENERGY STAR partner, we’ve got you covered when it comes to energy efficiency.
Premium Vinyl – Its thermal properties are far superior to aluminum, steel and stainless steel.
Glass Coatings – A transparent metallic oxide coating is 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.
Spacer Systems – Placed between the glass panes and further reduce temperature transfer.
