Customer Reviews for Frost King 1-1/4 in. x 3 ft. Fiberglass Pipe Insulation

Bought two of this to insulate immediate steam pipes coming out of the furnace. I noticed a temperature reduction of more than 10 degrees when compared to foam insulation alone. I was able to cut this easily with a utility knife. And because I read reviews about the adhesive failing, I taped aluminum tape cut into small pieces in the back for extra protection.

Worke great for wrapping a sweating vent pipe in attic

Handle with caution as the foil wrap can easily detach from the fiberglass insulation

High quality product which is easy to work with. I wish you carried more stock and also carried the special white tape needed to secure sections of insulation sleeves and to cover corners with roll insulation.

Needed this to install over a heat pipe after removing asbestos. Easy to cut, easy to install. I'm glad I also bought tape because the self-adhesive wasn't the best.

brittle with age and tape does not hold well

Great product easy to install

I wish Home depot can keep the item in better condition, you have to hunt for a good one

This is a very good way to insulate large steam pipes. Easy to install and easy to cut-to-size if needed. The sticky flaps are good to help installation, but be sure to secure this sleeve with a couple of nylon zip ties because the sticky-flaps will come loose over time.

Great solution for insulating very hot steam pipes. The perfect replacement for old asbestos insulation. Easy to install, excellent insulating qualities.

Good product i need to buy more this week

Excellent to deaden sound of washer plumbing installed in walk-in closet. Wrapped pipes in chase nice and quiet

Great way to insulate steam pipes. Very easy to install.

Easy to install and cut to size.

I should have gotten the 1-1/4 size - but used the 1-1:2 anyway

Fiberglass is hard to work with and comes apart around a curved pipe

Cheaply made falls apart i plan on returning them very expensive for something of such poor quality

It really conserves heat. I measured the temp at the steam pipe next to the insulation and it was about 210 deg F and a few inches away over the insulation it was about 120 deg. My cellar is noticeably cooler-a good thing. These all shed nasty fiberglass during installation. I recommend gloves (even medical gloves), eye protection and a dust mask as well as clothing you can easily remove particles from with a sticky roller. Several needed to be kept closed with zip ties.

Good Quality and Price

They all came smashed, the fiberglass was falling apart. Wasn’t the right size for 3/4 copper. All in all, bad product.
