From the remarkable folks at Build It Solar comes this heating conservation tip – bubble wrap your windows. Simply cut sheets of bubble wrap to fit your windows, apply some water with a spray bottle and before it dries stick the bubble wrap on the glass. While you can buy special bubble wrap designed for greenhouses, according to Build It Solar, regular bubble wrap will probably work just as well. If you number the pieces you use, you can stick it up again next year.
Bubble wrapping the windows cuts down on visibility, so it’s a strategy best left to back rooms of your house or apartment. Of course, LA’s so ugly it may not matter . . .
