How to Make Old Windows More Energy-Efficient

Many people around the globe have joined in the global conversation about greener living, energy efficiency and self-sustained buildings, simply trying to reduce their own impact and save a bit of money in the process. Energy efficiency is the ability to use less energy to achieve the same result e.g. replacing your lights with energy saver light bulbs provides the same amount of light, with less energy consumption.

In order to make homes more energy efficient people tend to focus on power sources and look into installing solar panels and the like. There are, however, a number of modifications and changes you can make to the existing structures that will improve the energy efficiency of your home by limiting energy wastage, especially regarding insulation and heat loss issues.

When improving the energy efficiency of a home many often consider their windows last, yet, surprisingly to some, one of the major sources of heat loss in the home are windows. Rather than spending a fortune on replacing every window in your home consider the home window repair and improvement tips below.


Sometimes the biggest factor in heat loss via windows is down to simple maintenance issues. Your first step is to identify and repair any damage, leaks (air leaks), and cracks in your windows, frames, and joints.

The kind of window frames your home has can be a cause for energy loss. Typical old windows have wooden frames, which are not particularly bad insulators, they are just very susceptible to weathering and organic influenced like rot and insects. Make sure to replace any severely damaged or infested frames and make sure there are no badly constructed areas that allow water to pool on the actual frames and treat the rest on a regular basis. Make sure that varnish, paint or other treatments are not cracking or peeling and consider resin or splicing techniques to repair these windows and prevent against further damp and decay.


Beyond the standard maintenance issues and after rather you ensure that there are no leakages, gaps or cracked panes; consider installing features that improve the energy efficiency of your windows without requiring you to replace the actual windows themselves.

Certainly, single pane windows are less efficient than double pane, triple pane or plated glass windows at keeping hot air in and cold air out, but changing every window pane can be both expensive and time-consuming. Tinting your windows is an option for keeping out unwanted hot or cold air, though for aesthetic reasons many opt for tinting only less visible windows.

Another option is the installation of interior storm windows which aid in decreasing air flow out of closed windows, making for better insulation. Interior storm windows will provide many years of use and can limit condensation taking place, limiting the moisture on your windows, prolonging the lifespan of your windows and making your home more energy efficient.

Additionally, take advantage of natural light, heating, and cooling when you can and save energy and money!
