    In the process of building my first propane cylinder forge and was wondering how thick of kaowool I need? A local boiler maker shop sells it in 1 and 2 inch thickness. Was thinking of doubling up on the 2 inch, is 4 inches unnecessarily thick?

    Two inches should be enough for anyone (Had to be said ;))

    Using any more is pretty much a waste of kaowool.

    I put a layer of 2 inch 2500 deg F and then a 1 inch 3000 deg F and coat it with SUPER 3000 refractory.

    Hi: just read you post, and I need some kaowool for a gas forge I just built. I' am in Welland On. Any chance I can buy about 6 sq. ft. Thanks.
    P.S. I was wondering if you need something to stick the wool to the sides of the tank.

    It's stiff enough to hold itself in place. I cut the pieces a little oversized and they held tight before putting the coating on them.
