Freezing cold weather last week made me think twice about our wood-burning fireplace, sucking out the warmth of the house through the flue.
Even with a tempered glass door and a damper closed, I can feel the air flow, especially in windy weather.
This is what I made yesterday to cover it, when not burning. Winter print fabric panel + insul-bright (needle-punched heat resistant insulation) + wool backing with attached sew-in magnetic snaps, which holds the whole panel tight to the metal case around the fireplace.
We also ordered a fire retardant spray for the baking. I hope it will help to conserve some heat of the house when it's really, really cold! Well, maybe not, at least it will make me feel better!
