Fanciful Fireplace Vent Covers

We are always looking for ways to cut down on energy costs and save money (hence the audit last week). One problem that needed to be addressed is our drafty fireplace.

It is a gas fireplace; we’ve used it twice. It lacks a blower, so it is not very efficient at heating. The vents above and below the glass are bringing in cold air and thieving our warm air. I had thought about making a cover for the fireplace (like this, only prettier), but Jeremy said all we really needed were fireplace vent covers.

I found several retailers online (like this company) that sell different colored magnetic strips that cover the vents. Home Depot and Lowes also sell magnetic vent covers, but only 8″ x 15″. We need two strips with dimensions 35.75″ x 6″ and 35.75″ x 6.375″. Plus, the HD/Lowes covers only came in white. That’s when I decided to make some magnetic covers of my own.

I picked up two rolls of magnetic adhesive sheets (12″ x 24″ each). To make the 35.75″ x 6″ strip for the bottom vent, I cut one sheet lengthwise. For the 35.75″ x 6.325″ strip, I cut three pieces of magnet, each 6.325″ wide.

Then I stuck the sticky side down on the wrong side of some fabric.

I lined up the magnet strip with the waste of the fabric. Above you can see the pattern weights preventing the ends from curling up. I used black electrical tape to enforce the seams where the strip was pieced together. This helped to prevent further curling, and added some support.

Here they are! Definitely a colorful way to block drafts. I wish the bottom cover could be a little taller, so that you wouldn’t see the brass of the vent. Increasing the height would make the cover too floppy. The top of the vent is not flush with the sides, so the center of the magnet wouldn’t have anything to cling to.

The fabric is a little sheer, so the black of the magnet is influencing the colors. I already had this fabric on hand, so it did not add to the cost of the project. The fabric coordinates nicely with the other cool colors (and bright greens!) in the media room.

Here’s the view from farther away. Jeremy and I are pleased with how the colors and pattern of the fabric tie in with the elements of the room. We’re interested for the follow-up to our audit to see the impact the covers have made (albeit small).

    I always think that the best ideas come from a need.  These turned out really well.  Just fyi you can paint the brass on your fireplace with heat resistant paint available at HD and Lowes.
    Great idea.

      I am glad you like the vent covers. Thanks for the tip! Painting the brass black would create a more seamless look.

    Here’s an alternative– the FIREPLACE FASHION COVER will attached to your fireplace doors or screens with industrial strength magnets that are hidden inside the cover, no modifications to or residue on your existing fireplace. Folds in thirds when you want to burn a fire. The fireplace fashion covers not only stop the cold drafts and heat loss, they look great. The FIREPLACE FASHION COVER also blocks the air from gaps around the doors and vents, they cover the entire fireplace.
