Replacing the 1/4" dog-house foam liner in a 2004 Prostar 197

[swbca]

This foam is fairly brittle and no longer well attached - falling off in places. Is there a specific product to replace it with ? If its for sound dampening 1/4" of zero-mass foam can't be doing much. If it was installed for a cosmetic finish perhaps just remove what is left and do nothing more ?

 

Suggestions ?

I removed the old foam insulation, and re-did with some generic sound deadening mat from ebay. Came out great, and MUCH quieter than the original foam.

@BobF (or others) How did you fasten it ? spray glue, trowel, or was it self adhesive ?

[BobF]

Self adhesive. I thought I'd have to use some type of glue, but it has held well for over 2 years. I used a wallpaper seam roller to press down the mat, and foil tape for the seams.

I used 3M-400L insulation. Works well so far, very light and easy to work with. It is available in multiple thickness depending on your need. Attached with 3M 90 spray adhesive, seamed with cloth electrical tape.
