This is high heat for wood, or gas fireplaces. Review: Fireplace installation - Works beautifully. No heat from fire to surface wall Review: Perfect! - Worked perfectly for insulating a smoky fireplace surround. I had a new chimney liner installed when I purchased my home last year. But when I started using the fireplace this last season I noticed smoke marks on my newly whitewashed interior brick. Researching what could be causing this...everyting from negative air flow in my house to needing to replace the surrounding door insulation. When I removed the door I found that I didn't need to replace the insulation...there wasn't any there to replace! This insulation kit worked perfectly! I did purchase two kits to double insulate..but I'm just that kind of girl. One covered the whole insert. ## Features - Replacement Black Fireplace Door Insulation.
