Doghouse insulation

Anyone have some good/cheap tips on how to add some insulation to my 95 Bounder's doghouse?

It's fairly square/flat and mostly plywood (It think). Anyone have advise on what to use or stay away from?

Your doghouse top is probably fiberglass with the bottom part metal and wood. (If its like my 96 Bounder) I used a self adhesive foil backed product from Home Depot. I works well as long as you get any oil residue off before you stick it on. It works wonders for heat transfer. I used two layers of it then put some mineral wool insulation (this is specifically for noise dissapation and is used in fire rated wall assemblies) and some 1"x1" wire mesh screwed to the bottom of the dog house so it stays in place. Its not a DP but really helped. Here are the products I used

I was looking at that stuff in Home Depot a couple of weeks ago, thinking about putting it in the doghouse on mine ('96 Southwind), but wasn't sure it would help - glad to know it works.
You kind of lost me at 'mineral wool insulation' though. I presume that's something like what's under the hood of a car - where'd you get that?

I got it a lowes in the insulation isle. Its very similar to underhood insulation. If you click on that link and "find your store" it will tell you what isle and bay its located. Its usually used in commercial construction for sound reduction and fire resistance. Its made from mineral fibers as opposed to fiberglass fibers. It can also be called rock wool insulation. I used it because of its superior fire resistance. It doesn't take very much so I used the rest under the dash to help quiet engine noise as well.

The foil adhesive backed insulation does wonders with heat and vibration similar to dynamat used to quiet automotive interiors but much cheaper.

Thanks
Adam

I just used a product called Armorflex, it is a 1" thick polyurethane foam rubber type and is very sound deadening material. We sell it at our business for expansion padding for our underground piping systems. Good to 221 degrees F. Made a huge difference in noise

So the product seems to just be for pipes ie circular did you use it to replace gasket around the seal of the doghouse?

I went with the Dynamat system. Doghouse cover in the Georgie Boy was fiberglass. The foil/foam heat reflector product went on the inside of the cover and the heavier rubber sound deadening was put on the top. then I carpeted over that. Much improved both heat and sound.

actually it comes in a roll 5' wide x 25' long. We do have it full round for insulating pipe in the field. I did the complete inside of the dog house and on the firewall where I could. I will be using the sound deadening insulation that HD sells, for up under the dash, I think it is the mineral or rock wool. Thought about using the denim insulation but, not sure if it's as dense

I need to pop off the doghouse cover in our new 2016 Newmar 3124 Bay Star to see what Newmar has done in there.

Thanks for the thread. Looking forward to learning more on this.

I found a race shop locally and called them. The guy had several boxes of the dynamat extreme and I got 5 sheets for $80, he even threw in a roll of the heat tape. I bet if you call around you can find several performance shops that have it and sell it. I did not consider $80 too expensive for the heat and sound factor. A lot of performance and car stereo places use it all the time for their builds.

The spay is a bit more because you need the gun, I guess you could just lay the doghouse upside down and pour and spread it with a brush and just be as effective, just watch the thickness as you pour. I just listed the first available there is a smaller size of the lizard skin for around $80. You don't need that much to cover the doghouse. I actually had enough dynamat to insulate most of my GEN bay to reduce the noise from it to the coach.
