Has any one tried this? I'm thinking of it as a "poor man's" version of 2-part (or 1-part) spray foam insulation.
For example - part 1 goes in one sprayer, part 2 in another sprayer, apply part 1 first, then spray part 2 onto part 1 to get the chemical reaction.....

No.. The 2 materials must be mixed thoroughly similar to mixing epoxy. If you did what you suggest there would be 2 problems.
1. The first chemical would just run down the wall and puddle at the bottom.
2. You would end up with a sticky mess that is near impossible to clean (requires acetone).
If you look at the nozzle on the spray foam kits you will understand. Its designed to mix the hell out of the chemicals before they exit.

Thanks, travellerw. gcrank1, cost - seems like the yield would've been much less expensive if it could've been done.

Quoting: Brettny Use foam board and caned foam around it.
This is the right solution. Get a foam gun and buy big cans online or at a contractor store. That would be the cheapest solution for a sealed foam insulation.
