Glass does very little to block the transfer of temperatures. Heat can very easily pass through windows and escape your home. Thus, if you live in a cold climate and use a furnace to heat your home, your windows can allow heat to escape your home, causing your furnace to work harder to keep your home warm. Thus, in order to keep your heating bills down, you need to improve your windows' ability to retain heat.
One Pane, Two Pane, Three Panes of Glass
As stated earlier, one pane of glass will not do much to insulate your home. Adding two or more panes of glass will not vastly improve glass's ability to retain heat, but leaving space between the panes of glass will improve the insulating properties of the window. If you have a double-pane window, the air between the windows will double the window's energy efficiency. Use three panes of glass will create two layers of air, which make a triple-pane window up to 30% more efficient than a double-pane window. Another way to improve the energy-efficiency of your windows is to use argon gas rather than normal air because argon transfers less heat than oxygen.
Using Window Film
Sandwiching glass between the panes of glass in your windows is not the only way to improve the insulation in your windows. Window films can be used to reflect heat back into your home without impeding the view from your window. If your windows do not have window film, you not have to replace your windows with ones that do. Instead, you can buy your own window film and install it on your windows. Window films can help to reduce your heating costs by up to 25%.
Buying energy-efficient windows can help to keep your costs low, but buying new windows can come with quite a price. To determine if you can afford new windows for your home, you can take out your heating bills and then determine how much you stand to save with new windows. Multiply the price of your heating by the percentage of your cost that you stand to save with your new windows. You can then calculate how much you will have to pay from month to month to finance your windows. As long as you save more money than you pay for your windows, you end up saving money. In the end, new windows might be just what you need to get your heating costs under control. Contact a company like Central Glass for more information.
