Rutland Products 1111 Fireplace Insert Insulation Fiberglass, 1-1/2-Inch by 10-Feet, 1-1/2" x 10', Yellow, Model:105

Insulated fireplace glass door frame nice and tight. Caution, make sure you have your dimensions right. The sticky tape when separated isn’t the stickiest but a dab of crazy glue sufficed. I attached the insulation with entire frame detached from front of fireplace and it was perfect. They should add a dark colour option. I was short 8” and used Rock Wool Insulation with a dab of crazy glue. Could have done same job with Rock Wool since it is fireproof as well.

No extra images on Amazon to find out if this is what you are looking for. Also poor labelling both on the website as well as the package. My order will have to go back to Amamazon, unfortunately....

easy to use and appears to be working, no cold air leaking from the gap after installation. the yellow color doesn't match edges of stone and the fireplace, if there's black color would be better.

I didn't like anything about it! It wasn't thick enough,supposed to be self adhesive but, the insulation wasn't attached to the adhesive strip, making it very difficult to apply to the insert properly. Certainly will never order this item again or, recommend it!

I did not use this for my fireplace, but used it elsewhere in my basement to plug odd holes here and there where the cold was coming in. And it works like a charm with good insulation properties.
