As the seasons change, many Dayton homeowners watch for the dreaded spike in their energy bills. If you don’t have energy efficient windows installed already, it is possible to watch your heating and cooling costs double or more. So how do you know if you have energy efficient windows or not? Here are 4 signs to look for in your windows.
1. Energy Star Ratings
Often the easiest way to tell if you have energy efficient windows is to look for an Energy Star® sticker. These stickers are usually located inside the sash of the window or on the bottom corner of the window panes. An Energy Star rating indicates that the window has met minimum performance standards for efficiency. They have been rated by a third party according to a set of industry standards.
2. Window Frame Materials
Another important indicator of the efficiency of your windows is the materials used in their construction. Aluminum, wood, and vinyl sided windows react differently to extreme weather. In particular, aluminum and wood framed windows can retract and expand, leaving air gaps that allow for drafts. Fibrex® windows are the best choice for extreme heat and cold because they remain stable at a wide range of temperatures.
3. Number of Panes
For the most part, today’s windows consist of dual panes that create a small air gap within the window sash. This air gap provides an extra layer of insulation for your Dayton home. In many cases, this air gap is filled with a gas blend that is known to reduce heat transfer through the window panes, ensuring that there is no significant temperature changes on the surface of the glass itself.
4. Glass Treatments
Finally, highly energy efficient windows are treated with specialized glass coatings that prevent harmful UV rays from entering your homes. It is not always possible to see whether these coatings are present or not. Some manufacturers indicate these treatments with small stickers in the corner of the window pane to help you tell what level of protection you have.
Aside from these indicators of energy efficiency, there are a number of other factors that may impact the effectiveness of your windows. If you discover that your windows are not improving the efficiency of your Dayton home, it is time to call in Renewal by Andersenfor a free consultation!
