i am building a hot smoker to replce my old nipper kipper.
plywood box and a seperate smoke box.
i need a fireproof material to go between the steel fie box and the timber smokehouse.
i have been told to use fiberglass cloth as i have 50m of 2m wide stuff.
if it fireproof? will it insulate between teh boxes suficeiently to stop my box catching fire?
what else might i have around or be able to get easily that will work?
I'd take a piece of it and apply a gas torch before using it.
Fiberglass boats seem to burn pretty fiercly once they get going.
G'day Carl,
Just from experience, I'd separate the two by a length of flue. (can be a foot or so....up to you)
The Temperature drops a bit, but you get better smoke, and after all you're not cooking, even if it's "hot-smoking"
If you throw a bottle in a fire it melts, fibreglass burns even with out resin :blowup:
Whellin' - there's a world of difference between melting and burning.Quote:

If the stuff Weisyboy has is truely glass fibre then it's a good insulator - it's been used for years for exactly that purpose

Having seen Fibreglass alone burn without resin is why I made the statement it does turn to an ash. You are correct in saying it is a good insulator as we use it these days in homes for insulation. There is also proof fires have started in this type of Fibreglass just through heat transfer from down lights no resin in sight.Quote:

The stuff doesn't burn it just gets hot to the point of white heat and crumbles to a grey powder which I think is what glass does if it's cooled too quickly. It does not continue to do this the moment the flame is removed from it so, in my book, it doesn't burn.
Glass is pure silica and that stuff neither burns nor supports burning - when was last time you set a beach alight?

tried it and it dosent burn it will turn to ash if you get it hot enough i had to use the oxy to get it that hot thow. lpg alone would not do it.
thanks for teh help guys.
shoulda just gone out and tested it myself in teh first place.
but it was raining and i would have melted.
:2tsup:
the smoker will be heated by a metho burner so it wont get anyware near hot enough to burn the glas sheet.
ill put plenty of layers so teh heat dosent get threw into teh ply.
Remember what they pack in a automotive muffler...
Plus welding & fire blankets
