Pen+Gear 12" x 100' 3/16" Bubble Wrap Roll, Small Bubbles

I use large bubble wrap in the winter for insulation on the windows. With the large bubbles against the window, attach the edges around the window with a clear, lightweight packing tape from Walmart. It does a good job of keeping the cold air out and helps to lower the heating costs. Check the internet for quality instruction on the application.

I ordered this to wrap our turtle's tank (48x24x24), our anole enclosure (18x18x24), our little 2.8 gallon tank of bladder snails, and our pet cricket enclosure (10 gallon aquarium). I also lined all our windows before hanging up plastic drop cloth or vinyl shower curtains. This is to insulate things in case of a power outage, or in the case of our windows, to stop all our heat from flowing right oit so I could save $50 on electricity. It works really well and I highly recommend it. It takes a bit to get it up, but once it is, it's very effective and it also cuts down noise.
