Thoughts on using urethane foam.
I want to install a small electric fan in our TT to help move air from the AC to the front. It is small enough that I have no concerns about mounting it to the wall but I am concerned about noise given the thinness of the luan. I was thinking I could firm up the wall with the expandable foam products they sell for home insulating but I'm not sure if this might cause problems with making the wall bow. The wall is a half wall beside the kitchen sink and has the shower stall on the back side. It also contains the various control panels, wiring and shower plumbing. My intent is to only fill the areas where there is no piping or wires. Any thoughts or concerns I should take into account?
