The U.S. Department of Energy research suggests older homes lose as much as 50% of their heat loss (energy costs) due to seepage around windows. This isn’t a result of poor construction, instead due to settling of older homes on their foundation and contraction/expansion during weather changes.
While there are many financial benefits to changing out our windows, the costs can still be prohibitive. Fortunately-we do have options. Some can actually be quite stylish!
