Fireplace Door Insulation

[mossman]

There is quite a bit of air seeping through the gaps around my fireplace doors. Is there a specific type of insulating tape, weather stripping, etc., that I can apply to the frame of the doors (i.e., the jamb) that will block this cold air.

Do you burn wood or gas?

Wood fireplace. Tried some regular weatherstripping yesterday and it blocked the draft nicely, but when I used the fireplace, the weatherstripping began peeling off due to the heat (expected). Is there a more heavy-duty heat-tolerant weather stripping for my specific application?

I'm going to try some Roxul stone wool insulation - just ordered it today. It's nearly fireproof, and you can purchase it through Lowe's online. What I don't use between my metal fireplace door and brick fireplace, I'll use elsewhere in the house. I purchased a bat of the Safe'n'Sound so that maybe i can minimize some of the outdoors noise. Safe'n'Sound is denser than Roxul Comfort bats, so it's not as good when it comes to thermal insulation. Safe'n'Sound is actually designed for interior walls, ceilings and floors. And since Roxul's products can withstand so much heat, I choose it to use behind my fireplace door. I was unable to find a suitable product at actual Lowe's and Home Depot locations, and the fireplace door insulation offered at local specialty fireplace stores was thin flimsy junk. So check out Roxul, and definitely watch that little video that's on its Website - the product is amazing.

There should be a rating plate on the fireplace that list the make, model and serial number of the fireplace. Post that information here.

In general, the right thing to do would be to order the correct gasket material for the glass from the fireplace manufacturer or a local dealer. There are all kinds of gasket material, ordering the right stuff will insure it fits properly and works correctly.
