Having an energy-efficient home is today more important today, given the increasingly high cost of living. However, when it comes to replacing old school windowpanes with the more modern double-pane versions it all comes down to the return on investment. Can the homeowner actually justify the upgrade, or are there options that can allow them to save on the energy-related household expenses by making those older model window panes more efficient?
For many years, single pane glass was the material of choice when it came to windows, but the truth of the matter is that they are simply not as efficient as double panes (with their layer of air between the two panes) when it comes to isolating the interior of the house from noise, or keep the home cool during the warmer months and at a comfortable temperature during those chilly days of winter. That can mean that the heating and cooling systems in the modern home have to work overtime to keep things cozy - and that costs money.
If you want to save and keep those single-pane windows then there is always the option of window film. The film can keep heating costs down - and reduce glare, but they are simply not as efficient when it comes to reducing heating and energy consumption costs. In fact, studies in North America have indicated that double-pane windows can save up to 24% in energy costs during the winter months and around 18% in cooling costs during the summer when compared to single panes.
The conclusion could not be more clear. In the long run, double-pane windows will simply pay for themselves - it's an up-front cost that can very easily be justified (and adds value to the home). Window film can be better than nothing, but it's not going to cut down that monthly energy bill as much as the double-panes solution.
