Its been a long time since i've last been here. Anyway, we recently switched out our old dryer vent hood because the old one had broken flaps. Though the new one does look nice, on the inside, there is now a gap between the vent and the wall. I'm not concerned about insulation because there is fiber glass surrounding the pipe. Now to fill in the gap, i seen people recommend using spray foam. The only problem I have with spray foam is its flammability. There is very hot air passing through the vent and I'm concerned about using this. Has anybody used this? Or is there an alternative?
