Engine comparment insulation

November 06, 2013, 09:36:50 pm

The insulation on the underside of the bed on our 91GV has deteriorated greatly. I'm wondering if there is something that I could spray on it to hold it together and make replacing it a lot less messy. I'm thinking that a solid foam would be a good replacement. Has anyone done this job before or have some insight on how to get it done?? Thank you and have a great day ---- Fritz

I am also just about to do mine. I am thinking Roxul and tough mylar, like Kozzee wrap (super tough), be really easy, and cheap to do...

I need to do mine to real bad, finding something water proof and reasonably heat/fire resistant is proving to be a challenge. The orginal stuff FT uses is quite pricey.

That is my next project I am about to do. I have an email from Rick Harper at Power Tech saying he could do better on the price of there Soundmat Aluminum Soundmat Sheets 1/2" by Power Tech | Power Technology Southeast Inc but it is only half inch thick. So my current plan is to cover it all in sheetmetal. Still looking for a local vendor where I can aquire some. I have a local friend in my neighborhood who used to own his own body shop in Flint MI. He said he would help me do it and he is a genius at that sort of thing. He also sells for Camping World now which has been helpful.

I plan to do this job myself and the first thing I'm going to try is to remove the old deteriorated stuff with a shop vac. I dont want to use water or air, so thought I would try the shop vac approach. I haven't decided what to put back in its place, that comes later. Thanks for the input on possible replacement material. Have a great day ---- Fritz

MAZ,

Someone did this on here recently. I believe he used aluminum soffit material.

Here is a well=proven solution for quite a bit cheaper than a few of the other suggestions;

EZ Cool Automotive Insulation heat barrier and noise reduction for cars, trucks,

I saw that at least one other user has posted his project using this product. I am adding the Roxul for added sound-deadening.

Best...

What does the factory use for new coaches?

I'll be checking around locally for idea today. If I don't find anything I will be ordering the EZ cool. I may not get the whole engine bay done before our trip to FL but the DW is sensitive to the fumes so I'll get the bed hatch seals soon and post pics.

Looks like it may be a good fix. I wonder if they would send a sample?

This guy is 30 mil a way from me. I just ordered two rolls. I will do two layers.

Hi, two layers is overkill, but cheap enough that it won't hurt you, and might take another couple of decibels off...

We stripped all of the insulation out of the engine compartment last weekend and took the coach out for a ride. There was no noticeable difference in engine noise at 65 mph, at the drivers position. I plan to laminate a layer of EZ Cool insulation to sheets of High-Temperature Rigid Fiberglass Insulation McMaster-Carr and McMaster-Carr I will use the 1" sheets on the walls and 1-1/2" sheets under the bed.

The EZ Cool was what I was going to use but I got a similar product with that was a about the same price. I only put the foam board on the bed, if need be after this next trip I'll put another layer of the WIREZ heat/sound shield up on the walls
