Time To Get New Windows?

Assess what’s important; Energy savings alone might not be enough

There’s no question that upgrading the windows in your home or business can save on energy costs. But before you make the investment, be sure you’ll get the benefits you expect.

Here are five things to think about when it comes to window upgrades:

  1. Energy Savings: Trimming your electricity or natural gas bill will be nice. Consider how many years of energy savings it will take to “break even” on your investment.

  2. Comfort: A better-insulated building makes for a happy family or work environment. The areas near the windows are not as cool in the winter or warm in the summer. How much is that comfort worth? The Oregon Department of Energy recommends windows with a U-factor of no higher than 0.30 A lower U-value means less heat transfer.

  3. Quiet: Better-insulated windows also help dampen noise from the outside. If you have multiple windows facing the street in front of your home or office, that could make a big difference.

  4. Functionality: If your current windows don’t open and shut easily, getting new windows will be a breath of fresh air – literally!

  5. Aesthetics: The four items above could help the resale value of your building and new windows will make it look more modern.

Before shopping for new windows, it helps to know the lingo:

  • Glazing: This refers to the number of pieces of glass in the window frame. For instance, many people today have double-glazed windows. Between these two sheets of glass is a sealed space filled with air or gas; the latter being more expensive.

  • U-Factor: The lower the number, the greater the energy efficiency.

  • Solar Heat Gain: The lower the number, the better the window is at blocking heat from the sun.

  • Low-E Coating: This coating reflects heat while still letting light in. However, while it is transparent, it does reduce visibility.
