Do you feel cold air leaking in when you walk by your windows? Ultimately, the best solution is probably to have your windows replaced with new, tightly sealed ones. But with an average cost of $300–$700 per window, this is not always financially feasible. If you want to reduce your heating bills and keep your home warmer without draining your bank account, here are a few options.
Purchase insulating curtains.
Instead of hanging up linen or cotton curtains, opt for thicker, insulating curtains. You'll find some made from fleece or felt. Other brands even make thick curtains "stuffed" with a layer of acrylic or down. Choose windows that are long enough to hang a foot or so past the bottom of the window, and keep the drawn shut throughout the window. The curtain will keep the cold air trapped behind it, preventing it from fully entering the room.
If you're in a pinch, you can purchase some thick fabric and just hang it over your curtain rods to create makeshift insulated curtains. You could even use spare blankets you have on hand!
Seal your windows with plastic.
Head to a local home improvement store, and visit the window section. You'll discover something called plastic window film or insulating window film. These products are essentially sheets of plastic that are sticky on one side. You unroll the sticky plastic and adhere it along the edges of your window frame. This way, the cold air gets trapped between the glass window and the plastic rather than blowing right into your home. Since the plastic will still "radiate" cold into the room, you're best off pairing your window plastic with insulating curtains for even more substantial heating bill reduction.
Push rope caulk into the groove.
Usually, the cold air will be seeping in from between the window frame and the sash. You can seal this space by pressing some rope caulk into it. Rope caulk is a sticky product similar to sticky tack. It comes in long strands, which you unwind from a spool. With rope caulk in place, you won't be able to open the window, so you'll want to pull it back off when spring comes. Luckily, it's as easy to remove as it is to apply, and you can just put new rope caulk in the window the following fall.
