Spray polyurethane foam insulation

[dgk]

You should try working on a trailer that has been sprayed--Forget it--Not a good product for trailers

Well that was my conclusion so I am going to foam the bottom only and use laminated sheets of foil on the inner walls but I will paint them (inner walls) with the r paint first. Have you ever seen the foam break away from the structure?

Any results with the closed cell foam?

I have used the closed cell fire rated two component foam with great success on a number of mobile structures.

If you conduit the trailer, tape the exposed face of the ribs, and wipe down the inside of the wall with a light solvent to degrease it, it should last for a long time.

I am planning on doing a full cavity fill when I put the Aluminum Falcon back together.
