This may be the best thing I have bought on Amazon yet. I was walking by our fireplace the other day about 5 feet from it and realized just how drafty and cold it was making our house. We bought this and I will tell you as soon as I put it up I didn't feel the cold draft anymore! It was so easy to install you just pull it out and the magnets stick to the metal frame immediately. They are strong and durable magnets but you are still able to remove and place it better if you need to. It's not heavy other than the magnets but even those are not super heavy. It comes in a vacuum sealed bag and folded so when you pull it out and put it up it has creases but as the days have passed since I put it up, those creases are almost all gone. I got one that fits perfectly and honestly it looks better with this on right now than it does without it. It is very durable and feels like it will hold up for a really long time. I am so excited and my heating and powerbill is too! I honestly will keep this up all year round as I am sure it will help keep my A/C from escaping in the summer. If you have a fireplace I 100% recommend this and for the price it is absolutely worth it!

We have intense summers where I live and I noticed some radiating heat coming from my fireplace even though my flue was shut adding unnecessary heat to my living room so I went looking for a remedy. I saw this and I immediately bought it. I don't know why I haven't thought of this or bought it sooner because its amazing!!! Its a quality made product, fits great providing good coverage for the entire fireplace, its thick and insulated extremely well, the magnetic adhesion seals off the area well making it very stable, and its very clean in appearance. It blocks heat/cold in every season and can also be used to keep pets out. Its a win win for me. Wish I had bought it sooner. Truly.

I highly recommend this fireplace cover. This product is amazing! I have been dealing with a drafty fireplace since moving into my house 4 yrs ago. I had no idea products like this existed. It truly has been wonderful to sit on the couch and not be facing the cold drafts. Now, I would say 95% of the drafts have been eliminated. My glass door handles are at the bottom of the glass doors and not in the middle so it is a bit difficult to get the bottom magnets to attach over them. Just a bit of cold air can be detected. I don't think this would be an issue for doors with knobs/handles in the middle. I pushed the dog bed up close with his stuffed toys blocking the bottom edge to address this. Again, I have handles, not knobs, which are at the bottom which I think is the cause of bit of cold coming in due to an imperfect seal. I like the quality of the cover, the multiple magnets versus other brands with fewer ones and the material which will puff after a while. (It comes in a vacuum-sealed bag.) The edges are trimmed as well. Overall, I am very happy with its performance. No more drafts!

This magnetic fireplace blanket is really effective at blocking drafts and keeping the heat in. Installing it is a breeze—the built-in magnets attach securely to the iron frame, ensuring everything stays in place. The size fits nicely, and the material does a great job of sealing out cold air. It’s a straightforward solution that makes a noticeable difference in indoor comfort. All in all, a fantastic product that lives up to its promises. Definitely worth recommending!

Product arrived promptly & well-packaged. Product's size, weight & overall description was "as advertised". Powerful magnets hold fireplace blanket in place & appears to be of good quality. Will need to measure the dimensions of your fireplace opening to order correct size (multiple size options available). The blanket looks good & keeps fireplace drafts at bay. Very easy to install & can be easily taken off/on. Price was fair. Would recommend this product to anyone in need of fireplace protection/weatherproofing.

Used this to cover the louvers in my whole house fan when using the central air on days too hot or humid for the fan. Too heavy for the magnets to hold it to the ceiling. No worries. Bought some heavy duty 3 M velcro strips and super glued them to the fabric. Attached the other side of the velcro to the fan housing and stuck the insulated blanket over the louvers on the fan. Fit great, no more hot air infiltration through the louvers. Keeps the upstairs noticeably cooler now. Easily removed if I need the fan on cooler days. Made of heavyweight fabric and feels like it's filled with insulation. Sturdy construction should last me forever. Saves me a lot on my A/C bills.

This is exactly what I was expecting. Good fit, strong magnet, seals off hot air from entering in the middle of our Tennessee heat wave. I couldn't be more pleased and I recommend highly.

This is a great product! I don’t know why I didn’t but one years ago. It is thick and fits well. It has minimized the cold drafts in winter and the heat/humidity creeping into the living room in the summer. It’s really inconspicuous too. I highly recommend!
