Meeco's Red Devil 1105 Fireplace Insert Insulation - Fiberglass Strip (10 ft x 1.5 in) with Pressure-Sensitive Adhesive Backing - Made in the USA

It works as expected. The adhesive is good and the insulation is thick enough. It looks like it sealed well. I will buy it again next year.

if you use this on your woodstove or smoker...it should be replaced yearly. I hadn't done it for years! Easy to install. Works great!

When I got this it didn't look like it would do much. The insulation wasn't as thick or as wide as i thought it would be. It worked great. It stuck lime it was supposed to and it stopped the air from coming in.

Easy to install. Fit was perfect

Manuf shipped the end of roll - the packaged product was not usable out of the box, did not have adhesive tape on half of the roll. Had to improvise, apply my own dbl sided tape. QC needs improvement.

Used this on inside of my fireplace insert surround. Surround sits on a rocky surface so needed this to stick to inside of surround and fill gaps once pushed against uneven rocky surface so cold air does not blow through. This works perfectly. Great insulation. The sticky side worked perfectly too.

This product did exactly what we wanted it to do. We have a gas fireplace insert and there has been cold air entering from around the edges of the glass screen/cover where it meets the existing stone surround (despite the insulation shoved up into the existing chimney by the installers). The Meeco's insulation has one sticky side which adhered well to the back of the fireplace glass screen/cover and I was able to fluff the foundation to make good seal to the existing stone. The draft is GONE. So happy we purchased this product; especially knowing it was certified for fireplace use.

First, gotta give it to them; as described, it's a "10' x 1-1/2" wide strip of fiberglass insulation" Shame on me; I missed the "fiberglass" part. Because of that, I paid such a hefty price ($18.05 plus $5.22 shipping) thinking that it was particularly fire-proof and not prone to being blown into my living room via the fireplace insert's fan. I was wrong on both counts. For those needing to insulate the space between a fireplace insert and a (masonry) fireplace, there are a few points to consider when using fiberglass for that purpose. Fireplace inserts usually have two layers of sheet metal between it and the masonry. The first surrounds the actual fire box, and it gets very hot. The second is separated from the first by a couple of inches or so. The air heated between the two layers is what's blown by the fan into the living area. The space between the outer layer and the masonry is what's to be sealed via insluation. My insert says the temperature of the outside box does not exceed 200 degrees Farenheit. So fiberglass should be OK for that. Be sure to check that outer layer to see if there are any holes in it. Mine has several holes, some to enable the gas line and wiring to pass from the outside of the unit to an area between the two sheet-metal boxes in the bottom section that holds all of the gas-pipe plumbing and control components. The areas of four holes are several square inches each. If I had just stuffed the insulation from the product around the perimeter, I have to believe that the swirling air from the fan would pick up some of that fiberglass and blow it into my living room. If, that is, the small amount of insulation provided would have sufficed to seal the perimeter. The double-stick tape just gets in the way--no way to really stick it to one side of what's being sealed without (easily) ripping the fiberglass from the tape. Given the insufficient amount of insulation and the messiness of trying to install it, I ended up throwing it out. I then re-started with 1.) a larger package of fiberglass insulation and used 2.) metal duct tape to seal the outside sheet-metal box that is next to the insulation to ensure that all holes were covered. Be sure to get the metal tape; the fabric stuff will surely separate from what you stick it to, usually before the end of the heating season. Using this approch ensures that the insulation stays on the outside of the box and cannot enter the heated air blown into my living room. Together, both of these replacement products did the whole job, i.e,. filled the gap between the fireplace insert and the brick fireplace and ensured that the fan won't blow fiberglass into my living room.
