    my thimble has about 1.5 inches from the outside of the insulated vent pipe to the round sheetmetal wall. They say go 3 inches to insulation.
    does that mean that I cant put fiberglass insulation around the sheetmetal round... I have to go an additional 1.5 inches clear around the outer ring..??
    Does Home Depot sell a TOTALLY non combustible insulation that can be formed around round objects..??thanks

    duravent big E breckwell I think from the instructions that you can wrap the round in fiberglass.... that gives you a 1.5 inch air clearance and the pipe itself doesnt even get that hot
