Basement insulation

[cdat]

A great deal of the insulation in the engine compartment and generator compartment is/has come loose from the floorboards and is handing down. The insulation appears to be a foam based covered with a plastic, the plastic is also exasperating from the from the foam, and the foam is crumbling and coming apart.
Any suggestions on a replacement insulation, is it necessary to have the insulation, I would think so. Can I glue a foam board type up on the underneath of the floorboards?

Thanks for any suggestions.

Hi John,

To my knowledge this product is what Newell coach originally used and can be purchased from them by calling Newell Parts or by using the link below. Same product different source. I do recommend that you give Newell a call just to verify this is the correct insulation.

John, this subject has been discussed on here in the past but not to the greatest of detail and it's probably time to advance the record. Many have only used the lighter duty household or HVAC foil coated bubble wrap which can be found at some home improvement stores or here on the web. It's really kind of a weak product but I guess it suits those needing to pinch their pennies.

There are a couple of different types of insulation I would personally recommend. Depending on what areas you would like to insulate and what you would like to accomplish. You can insulate these babies better than factory if you choose.

The product Sean (NewellCrazy) just posted is a great product and yes it is used by Newell Coach along with the products I am describing below. There are some people that have preferred not to opt for this improvement while repairing their coaches. I strongly disagree with those decisions. Go for the Gold when working on your luxury coach and not skimp. It will payback in energy savings and sound comforts.

The Newell factory has done a great job compared to most other manufacturers out in the RV world. But, if you so choose you can take things a step further. I myself have done so on other coaches, autos and boats over the years and many of those products are still being used today.

I do not like or recommend the foam board for use on overhead areas in any moving vehicle unless in is encased somehow like maybe a basement door shell, but then again that will still most likely leave nooks and cranny's left unprotected. I would go with a closed cell spray foam insulation under your basement ceiling, it is a two part foam you can apply. In fact the manufacturer and bottler are not too far from me, but they only sell directly to private label manufactures or distributors. I'll provide you with some links for that product below.

The engine and generator compartments are another story and there are commercial grade aircraft and yacht engine room insulation that I have found to be the best. Here is a link to a new thread covering the engine compartment installation. http://www.luxurycoachlifestyle.com/forum/general-technical-discussion/5099-luxury-coach-engine-compartment-soundproofing.html. You will find diagrams and examples at this link. We will update things as we have additional information to share.

This post will be updated as I dig up my information and photo's. Please be patient with me and standby. thx

Don't go with the cheap stuff. You won't be happy with it and some things you need to go a step above better. That's my 2 cents. ;)

Thanks for the insulation info. Theres some places in our coach that will be needing replacement.

[cdat]

Sean, appreciate the info, might go that way, will wait and see what Ken comes up with.
Ken, no hurry, I'm just gathering info right now, probably won't tackle this until later this year. I don't want to do a cheap job, I'm trying to keep the same quality or better when I replace things. I need to work on my search skill, I did a search for insulation, didn't come up with anything.
Thanks for the help

I have used Armaflex foam insulation around the engine area of my coach, this is a black flexible flame resistant insulation that comes in a variety of thicknesses. I found it's combination of stiffness and flexibility made it easy to handle. It lacks the aluminum reflector on the material that Sean posted about. I've heard of people using plain polystyrene or urethane foam but there is no way I'd use those around the engine compartment due to the fire hazard. I have used those materials for insulating other places such as storage bay floors and walls.
