Spray foam insulation help!!!

I'm looking to have closed cell spray foam installed under my home. We live in northwest Florida & Im having condensation/mildew/high humidity problems in my home (during the summer) due to a dirt crawlspace & it having excessive moisture. Unfortunately Noone is willing to do it so my husband & I will have to DIY. My husband is dead set on spray foam in a can & no other kind. I've been trying to do my research & am lost. I'd like something with some fire resistance as thats one of my fears. I've found 2 brands (AKFix 840p & Vegabond purple). I've read that it needs to be covered but our home is so low to the ground that it's not possible. I've also read that if it did catch fire the fumes would kill you quicker than the fire would. 1. Which brand would be best? 2. Will it be OK not being covered? 3. Are the fumes really that bad if fire did occur? Any tips/tricks would be greatly appreciated. submitted by /u/ProgressImmediate140 [link] [comments]
