Just as layering clothing keeps you comfortable in a variety of weather, layering panes of glass makes your windows more efficient. Double glazed windows (glazing is the traditional term for glassworks) feature two panes of glass with dead space between them. This keeps the winter cold outside and traps your air conditioning indoors in summer.

If you currently have single-pane glass, you can save up to $465 a year when you replace them with Simonton double glazed windows, according to the EPA.

Not All Double Glazed Windows Are the Same

Simonton Double Glazed Windows

Double glazing will always provide more energy-efficient windows than single glazing. However, some products perform better for longer. Standard double glazed windows simply hold trapped air, while premium models use dense gases like argon or krypton which prevent heat transfer more effectively.

A poorly made window lets the trapped gas leak out in just a few years. Simonton double glazed windows are carefully sealed so the trapped air cannot escape. Their careful manufacturing process, quality testing, and certified installers all help assure you as many years of comfort and energy savings as you expect.

Options for Energy Efficiency and Noise Reduction

Are your eyes glazing over looking at product specs? Here’s a quick rundown of what to look for in replacement windows:

  • A proper spacer between the panes to minimize heat transfer
  • Low E coating to block heat gain and infrared and UV damage
  • Argon gas for a cost-effective upgrade, or krypton for the highest efficiency
  • Laminated glass for improved sound reduction
  • ENERGY STAR certification for the best savings

Are Triple Glazed Windows Better than Double?

If your only concern is making your home as energy-efficient as possible, then by all means, swing for triple-pane glass. The added expense takes perhaps 20 years to pay for itself in energy savings, though. Some experts don’t even believe there’s a noticeable difference between double glazed and triple glazed windows.
