How do I cover and close my fireplace opening to conserve heat?
I don’t use my open (rectangular) fireplace. I’m sure there is a lot of heat being wasted even though the flue is closed, as they leak air and provide no insulation.
I’d just like to safely fit in some sort of cover to close it up… perhaps rigid foamboard (plus cement board?) with a decent R rating. I’d also like to make it attractive or at least not ugly.
Any recommendations? Anyone done this successfully?
I couldn’t find any marketed product on-line.

My daughter has an old brown stone with a fireplace in each room. She is waiting on using them until they can afford relining.
Her fireplaces are all covered as follows:
Measure that pink panther thick as you can get to the size of the opening. Remove the paper backing and glue to sheet rock of the appropriate size. Attach to opening with building adhesive. When fastened to opening, paint the sheet rock the same color as woodwork and put a bowl of flowers or whatever in front.
Her fireplaces look nice and I’m sure no heat is escaping from the rooms.
