FrothPak/Touch n’Foam Closed Cell Spray Foam
We have rim joists to insulate and I’m hoping to do it myself.
FrothPak has a frothpak insulation and a frothpak sealant. They both list rim joists as an option. Does it matter which one I use? I think the sealant is only for penetrations and junctions but the insulation can do double duty.
Also, any suggestions on FrothPak vs. Touch n’Foam?
Also, any comments on the ambient air temperature required and how much wiggle room there is?
