Before you run out and buy just any old window you should consider several things. This window is going to be with you for some time and can make a dramatic effect on your house if you let it. Windows can not only give your house a fresh new sense of style, but they also control the way energy is passed through your house, and the way that you can either cool or keep heat in your house.
R-Values and U-Values
Looking at an R-value of a window means that you are looking at the windows resistance to heat loss. This meaning the higher your R-value the better the insulation you have. A U-Value is the measure of heat transfer. If you have a low U-Value that means that heat does not transfer very well through this window. If you live somewhere cold you should definitely have a low U-value to counter heating bills.
Replacement window glazes
Keeping multiple layers of glaze on your windows is another way to insulate your house. Having good amounts of glaze on your windows can be as important as the window itself. Another way to increase energy efficiency is by installing insulated glass units. These glass units contain air pockets that can be filled with argon or krypton. These are all things that can lower the U-Value of your window.
Solutions for a warmer climate
A warmer climate suggests a different approach to windows. It suggests low E-coatings, these coatings can reduce solar heat transmitted through the window pane and into your home. This can take the U-V light off your furniture’s fabric which wears down over time. Just one other way that window solutions can save you money.
