I received my fireplace cover on Thursday, you are so fast, less than a week from the date I sent you my dimensions. It is wonderful what a great idea! I am so happy we saw you at the Home and Garden show. I am attaching pictures. I wanted to say how much warmer my sunroom is and also the hardwood floor with the cover on my fireplace. You can see how it is containing the air because the cover puffs out a little from holding the air. We love it. I will be telling my neighbors about it. I can’t wait to see how it effects my heating bill.
