Engine cover insulation question

I noticed the insulation/sound barrier material that is on the underside of my engine cover underneath the bed has come loose. When the coach was built the material was tucked under metal trim that goes around the entire bottom of the engine cover. This is on the engine side of the cover. I removed the bed today to try and fix it but I am unable to tuck it back in underneath the metal trim which is on all 4 sides and installed with rivets. I was considering removing (cutting) the part that is loose and hanging down and replacing that section with some type of similar or even better insulation material. I would need to replace about 1/4 of the bottom side of the engine cover insulation. Maybe some type of a special foam product that I could glue or screw if it was hard. Any suggestions of what to use.

Maybe something like this.


Bonded Logic Heat/Sound Insulation - JCWhitney


Or this.

Only things that concerns me is being used in a wet area. The stuff that's falling down has a clear plastic over the insulation. I think water could splash up traveling on wet roads.

I have heard of a rubber product that has an egg crate look on 1 side but have not found any online. Anyone??

Ok slow down on your suggestions . I think I found the cream of the crop but it's pricey at $15.00 Sq. Ft.

Mine did the same thing about 5 years ago. I used aluminum strips available from any hardware or home center. Tucked the ends above the factory metal edging, then put screws into the center. Still holding the original material in place just fine.

That's a very wet environment. If you do change the material it should be waterproof. The pictures I'm attaching will show the water flow marks on the material.

Thanks for the Pics. That was my first thought as well. Mine has torn a little from handling it but it's salvageable. I was just afraid it would seem a little sloppy since I could not tuck it back in under the original metal framing. But who am I kidding. I'm the only one who would know it. I'm a little anal like that sometimes. It can be a blessing and a curse. Did you add the foam around the edges? Yours looks good. I might give it a try.

I decided to take your advice. I used some aluminum foil tape on the edges of the section that came out of the frame. It looks pretty good. I'll finish it up with some aluminum strips as you suggestion to cover the foil tape. Sometimes you have to remember the KISS system and not go to crazy on certain things. This is definitely one of those situations. Thanks for helping me keep things in perspective. There will be plenty better ways to throw money at my projects to maintain and upgrade things .
