Just curious , for those who have Roxul stuffed up as a block off plate already can you line the Roxul with heavy duty aluminum foil to help reflect the heat vs pulling the insert out and fabbing up a plate out of sheet metal?

Last I knew Aluminum foil was for roasting potatoes?

As my neighbor would say, "sounds like bishbosh job!"
 
Aluminum can burn. That's what it's so dangerous to have aluminum wiring in a house. A loose connect and...poof. Even foil faced insulation can present problems in a house fire.

I wouldn't cut corners here.
 
Should work. I don't recall ever seeing the aluminum foil on my grill catching fire. And if that block off plate gets as hot as my grill you will have bigger problems on your hands than it.

ETA: Just checked. Aluminum foil melts, not ignites, at 1220F.

Now if your foil was made out of Tungsten instead of aluminum then you would have something.
 
Well, at least Ed got one good answer....
 
I don't think I personally would feel at my SAFEST with just foil in there. Just me.

You do realize that the insulation on chimney liners is wrapped in aluminum foil don't you?

Aluminium wire has a tendency to move around when it's hot, working it's way out of a connection (not designed for AL wire) and creating a high impedance connection. Then it heats up and will burn back the insulation until it gets to something that will catch. Aluminium wiring doesn't burn, it just gets too hot if not terminated correctly.

But it does protect you from aliens when woven in a pyramid.
 
I don't see much of a safety issue either but I don't think it would be all that effective or durable. But hey cant hurt to try.
 
You don't have to pull the insert to make a good block off plate, many of us have done it with the insert in place, many threads on how to do it. Just make it in two pieces, use cardboard for a cut out.

Plus, not only does aluminum foil protect you from aliens and the NSA stealing your thoughts, it improves TV reception immensely...

Thanks, I do realize that. But which side of a liner has the foil??
 
The left side. >>
 
I'd be inclined to recommend an approved method.

Please advise the OP of "approved" methods and materials for block off plates and approved by who.

No problem smarty pants. They specify 22 guage blue steel. His manual likely varies some from this, but this should serve to point out that one's manual likely tells them how. [Hearth.com] Aluminum foil
