picture this stuff
Amazon.com: WATERHEATER BLANKET: Home Improvement with white plastic on one side and the shiny foil on the other. foil side goes in. It comes with a narrow strip so hat the foil is actually spaced off of the tank to give a bit of an air space. How they determined that it's R5 I have no idea. It just has a big R5 on the packaging |
