### ⭐⭐⭐⭐⭐ Used with brick fireplace
*by E***S on June 25, 2025*

Even though my fireplace is brick I was still able to use this because my fireplace cover is metal. So I just stuck it to the inside of the cover and pushed it up against the brick. Perfect size and keeps the summer heat from coming in the house. This cover is a good weight and quality.

### ⭐⭐⭐⭐⭐ If looking at this and think you need something like this, just order it. You won't regret it!
*by R***O on May 31, 2025*

This kept soooo much of the cold air from coming into the living room through our gas fireplace in the winter.It allowed us to lower the heat level in the house just to heat the living room causing the rest of the house to be sweltering hot.The quality is beyond what I expected. Thick, clean looking, not bunched up and noticeable, sticks extremely well with the included magnets.This was a cost saving purchase with the added comfortability factor.If you have a fireplace that lets in a lot of cold or hot air, measure it and order.You won't regret it.

### ⭐⭐⭐⭐⭐ Measure carefully the metal that this cover’s magnets will have to make contact to hold.
*by P***N on February 19, 2025*

The size I ordered was very close to the opening of my fireplace. Inside that tiled opening was metal - with vents at the top and bottom. I do not have a glass door. My builder cheaped out with a metal mesh “curtain.” I might have ordered tiny bit smaller and still have enough exposed metal for the magnets to grab - but having read the reviews of others reporting that magnets were not at the very edge of the fabric screen, I decided to go for the size closest to my actual opening. Measuring from the inner edges of the tiled opening (not the metal inside the tile), I had a 45.5” wide by 36” tall opening. I ordered the 46” by 35” size since that was the closest to my actual opening. Side to side, the fit is close to perfect. The side magnets have a good grip to the inner metal. The top and bottom magnets hold well, too. The cover does leave an inch of uncovered metal at the bottom of the opening, but it does cover all the vent openings. The cover itself matches the specifications on the seller’s description. So far (3 days) the magnets are holding great but I have my doubts that these are powerful rare earth magnets. Fortunately, I have some very powerful magnets that I can use to supplement or completely replace if necessary. The cover definitely has eliminated heat loss through the fireplace - which was happening even though the damper is completely closed. I can tell that the furnace is not coming on nearly as much as it was before I hung the screen. The real test will start tonight when lows will drop to the teens and continue for three days. A couple of minutes to install, looks OK, low cost, and a lot faster than cutting foam core board or foam insulation board to the precise size.
