There are a lot of factors that influences the energy efficiency of your windows. With today continuous inflation in fuel prices, it is only natural for homeowners to look for ways to minimize their energy cost and one easy way to do that is to minimize the use of your HVAC system. Many people have no idea that your HVAC system, as reliable as they are, is responsible for more than half of your total electricity bill. And one thing that can reduce this is to install energy efficient windows that provide good insulation for your home to minimize your use of your HVAC system. So now, the question is what makes window energy efficient? What are the factors that influence the efficiency of your windows? Here are some of them:

Heat Transfer

First, be aware of this factor. It is your windows job to allow light inside the home. But it is also their duty to block that heat or cold from passing through the glass. Energy efficient windows that have low U values can do this task efficiently. They can block the heat and the cold from passing through the windows.

Panes and Frames

The panes the frames of the window replacement are also very important. Single panes provide poor insulation as compared to double paned glass. Energy efficient windows are usually made up of several panes, which means that the exchange process of temperature trading from and to the indoors and the outdoors is a lot slower. The frames dictates how slow or fast the temperature exchange is at the edges of the windows. Wooden frames tend to warp when exposed to extreme weather conditions, making it less efficient in sealing your windows. Vinyl and fiberglass on the other hand do not, making them more energy efficient. Be sure to refer different transom substitution agencies before making a decision.
