1. Cover Those Drafty Windows
During a major cold snap, cold air will find its way through windows and doorways.
Make sure all of your windows are closed and sealed. If you have storm windows, make sure you’ve installed them out- side during the coldest conditions.
Use removable caulk to seal aggressive, windy cracks. If you don’t have caulk, tape some thick plastic over the cracks, or stuff them with towels or blankets.
Clear shower curtains can help increase the insula- tion value of your win- dows, while allowing light in during the daylight hours. Simply tape them up over your windows on the inside. Any kind of plastic sheeting, including painter’s drop cloth, will help fight heat loss.
Cheap Trick: Simply stick a sheet of bubble wrap directly against the glass and it will stay in place.
You can still see the light through the bubble wrap, but your windows will be much better insulated. Obviously, you may not want to do this to every window in your home for aesthetic.
