Replacement Windows Reduce Energy Costs

Snow FrameReplacement windows are on the minds of many building owners as we experience winter’s cold and wind. It makes good sense to include replacement windows as a line item in your home, office, or plant remodeling budget.

Did you know that upgrading your old, out-of-date windows can save up to 30% on heating and cooling costs? When you install replacement windows, you can feel good about saving money as well as increasing occupant comfort and reducing your building’s carbon footprint.

Windows typically make up the majority of the openings in a building envelope. Openings allow heat to escape in cold weather and allow heat to enter the building in hot weather. Fine Homebuilding describes windows as “thermal holes” and calculates that “an average home may lose 30% of its heat or air-conditioning energy through its windows.” According to Energy Star, “Lower energy consumption also reduces greenhouse gas emissions from power plants …” To maximize your comfort, save money, and lower your carbon footprint, consider replacing old windows.

But you wonder, “What about making improvements to the windows I already own?” Retrofitting existing windows to improve their energy efficiency can be a good solution in limited cases.Energy.gov suggests that “you can improve the energy efficiency of existing windows by adding storm windows, caulking and weather stripping, and using window treatments or coverings.” Although this seems like a practical approach, replacement windows may be a better long-term investment if you plan to own your building for several years.

Optimal energy efficiency can be achieved by crafting a customized energy solution for your unique location and circumstances. Kolbe Windows & Doors, Marvin Windows and Doors, and Loewen are reputable companies offering quality energy efficient solutions. Keep in mind that proper installation will also reduce air infiltration. Replacement windows should include the following for maximum insulating value:

  • High R value will aid resistance to heat loss
  • Low E glass coatings will block heat transfer
  • Multi-pane units add glazing layers and insulating air space
  • Specialty insulating gas in the space between glass layers provides insulation

These elements work together to deliver energy savings and comfort in extreme summer and winter conditions. The savings on your utility bills from energy-efficient windows will be evident every month. In fact, energy-efficient windows eventually pay for themselves due to lower heating and cooling costs.

Potential buyers of your building will value your investment in newer, energy efficient windows. Energy efficient windows are readily available in a variety of sizes and shapes to compliment the design of your existing building. Consider the following additional features when shopping for replacement windows:
