We reported last December that up to 30 percent of a building's heat is lost through its windows. That's a lot of extra energy being wasted to compensate for such a loss—not to mention money. We've found a very simple, cost-effective way to deal with the heat we'd otherwise be losing through our windows:
The lovely lace curtains of summer...
...traded for blinds and thermal curtains (which we untie at night to cover the window entirely).
Thermal curtains (available in a variety of sizes, colors, and prices) can block a significant portion of heat loss through windows in your house. And if you're of the DIY persuasion, you can buy
and sew that onto the backs of existing curtains or cool fabric you find at your local store. Now we're cooking.
If you're going to attempt this in parts of your house, I'd recommend bedrooms, common areas, then bathrooms in that order. And if you're going to retrofit every window, err on the side of frugality and check outlet stores online or in your town to track down overstock items you can get a great deal on (we recently found a bunch of thermal-backed curtains for $6/panel, down from $40).
You can experiment with tying back your curtains during the day to let the solar rays in, and letting the drapes hang down over your windows after dark.
