ArmorDillo Metal Protection Film 24" x 200' Duct HVAC Protection Film. 100% USA Strongest, Easiest to Use Duct & HVAC Cover, Blue Clear Protective Film, Surface Protection Film, Dust Protection Film

I needed to do some ductwork covering in my crawl space. This is not a fun job. The ArmorDillo attaches itself very well to the ducts, but even better to itself. This is a two person job. One person needs to hold the roll and the other wrap and cut. It takes some good coordination. It does not tear, which is a positive.At this point I don't know how long it will last, but since it is a closed crawl space, it should last for as long as the house is standing.

At first I was not a fan of this product because when I started to unravel it my fingers went through it. However, I decided to give it a try because the mold specialist swore by this product. My only issue was it stuck so well that it took two people to handle the long strip so I could cut it in half to cover my ceiling vents. It has been 5 days so far and it still sticking even in the bathroom with all the steam.Through hiring the mold specialist I found out that your central AC vents should be closed and blocked off with this product to prevent warm air in the winter from flowing into the attic, which can lead to mold. My Central AC was used soley for the summer months as I have forced hot water baseboards for the winter months.

it really didn't stick over the vents on the ceiling we had to tape around the edges. it tuck on for about 2 hrs but then slowly by morning it was dangling off. So wouldn't buy again though the price was so much better then Home Depot .

not sticky enough.

Does not stick to the ductwork.
