Double Pane Windows

Double pane windows can be wonderful, but expensive. We’ve outlined some of the advantages and disadvantages of double pane windows below.


They save money. Even a clear glass, double-paned vinyl or wood-framed window can reduce energy usage by up to 24 % in cold climates (such as Minnesota) during the winter, and by up to 18 percent in hot climates during the summer, when compared to older, single-pane models.

They are great for the environment. The energy you save means you’re burning less fossil fuel and creating fewer greenhouse gas emissions.

They break the sound barrier. Double pan windows can insulate your house form noise pollution. This is particularly valuable if you live in a noisy area, such as near the air port.


Double pane windows are expensive. They are an expensive option in a new house and it is expensive to replace old windows with double pane options. A mid-range window will cost about $600; while a high end option is about $850.

If you have the money, however, double pane windows are a good investment. You will see reductions in heating bills.

If you don’t have the money, consider making cheaper changes to the existing windows. Caulk around all trim and stationary parts and weather-strip the moveable parts, to cut down on air leaks. Install insulated drapes or shades to reduce heat loss in winter, and install solar screens or awnings to reduce solar heat gain in summer.
