Yet another day of near record cold here and I realized that most of the winter I’ve been neglecting one of the simplest things I could be doing to warm my rooms – closing the curtains!
Yes it’s true – even The Energy Geek forgets the basics.
Why is closing the curtains so important? That little air gap between the window and curtains acts as insulation and can cut the heat loss out your windows by half or more. This is pretty significant when you consider that the windows may be sucking more heat out of the room than the walls.
