Roxul and block off plate

[CheaperthanYou]

Another Roxul and block off plate question, and a thanks or all of the previous help and andwers.

I made my block off plate today and it came out ok. I need to seal it and screw it in.

I put the Roxul above it. Is it ok that the Roxul touches the liner and the plate? It's not going to burn or melt?

I packed mine against the liner.

Isn't that what it's for, to pack around the liner?

I think it's rated to a couple thousand degrees if I'm not mistaken....

Roxul is fine to put against the liner, and even a stove if it is permitted by the manufacturer.

Melting point: Approximately 2150 (1177 )

pack it in tight and seal er up

At 2100 degrees the roxul is the last thing to worry about. I put a propane torch to a piece and it just shriveled up. No flames.

Does roxul insulate differently than most other insulation material? I've seen several comments about "packing it in tight" or "pack it in". On most other insulation materials I'm familiar with, like fiberglass or blow in insulation, you always want the material to be kept somewhat loose since it works by trapping air as part of the insulation process. Are you sure roxul works best when packed tight?

Roxul is Mineral Wool Insulation. It is a different beast than fiberglass as it is more condensed, and yes you pack it in, it is designed to work that way.
