Baller_ swbca Posted May 29, 2022 Baller_ Share Posted May 29, 2022 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 ?

Baller BobF Posted May 30, 2022 Baller Share Posted May 30, 2022 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. ebay insulation link Edit: link is blocked, so just search ebay for "heat shield insulation" Link to comment Share on other sites More sharing options...
Baller_ swbca Posted May 30, 2022 Author Baller_ Share Posted May 30, 2022 @BobF (or others) How did you fasten it ? spray glue, trowel, or was it self adhesive ? Link to comment Share on other sites More sharing options...
Baller BobF Posted May 30, 2022 Baller Share Posted May 30, 2022 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. Link to comment Share on other sites More sharing options...
Baller_ swbca Posted May 30, 2022 Author Baller_ Share Posted May 30, 2022 Beautiful !! Link to comment Share on other sites More sharing options...
Baller_ DW Posted May 31, 2022 Baller_ Share Posted May 31, 2022 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. Link to comment Share on other sites More sharing options...
