Sound insulation of doghouse

You need to see how much room you have. I replaced my 1/2" material that came from Tiffin with 2" rockwool. Then I put a 1/2" layer of fireproof material over the rockwool. I also used a gallon of roll on sound deadening material to roll about ten coats on the inside of the doghouse before I installed the insulation.

Good luck.

I replaced it with "B-Quiet Hliner", a 1/2" thick thermo/acoustic foam with a reinforced aluminum skin on both the doghouse and under the driver and passenger side floors. According to the manufacturer, "It reduces engine noise in the interior of the vehicle and also reflects the majority of the heat from the engine." My before and after sound measurements showed about a 10dB reduction at 2,000 RPM stationary. On the road, we've also found a noticeable reduction in the temperature of the dog house after several hours of travel.

Dutch,
How much 1/2" material did you order to complete the job and did you need additional adhesive to make it adhere properly?

I bought two 12.75 sq ft sheets, but one sheet got the job done, albeit I skimped a bit on the outer edges of the floors where the heat and sound have little effect anyway. Different sized dog houses will take more or less material of course. As I recall, the shipping cost was pretty reasonable, so you might order just one sheet first and see how far it goes.

If you clean the surfaces well, the self-adhesive is quite strong. Make sure of your cuts and positioning before applying it, it doesn't pull away easily to reposition it.

Mine's an F-53 as well with the same poor original aluminum/foam liner. I'll do as you suggest and start with a single sheet and see how it goes. Thanks for the input Dutch.

I used the sound deadener sold by summitracing.com. Search for their Summit Racing brand...cheaper than Dynamat, seems to be the same. Has stuck well for a year now.

Chassis is Ford V10.

Which chassis do you have? Ford or Chevy?

Thanks to all. I installed dyna mate and the difference in noise I hard to believe. Sound reduced by a lot.

I used DYNA MATE on my 1999 v10,what a difference with the heat and noise,

Whatever you install, make sure that it will stand up to a flame test.

My buddy put in something on his 87 class C, and it caught fire while going to Las Vegas in June. When we got back home, we put in 1.5: air duct insulation. We gave that a flame test, a BBQ lighter flame to the product. It was not effected by the flame directly on the insulation material. It is also rated for flame spread (that it will not do it) and is rated to self extinguish in order to be installed in buildings.

He kinda freaked out when his motorhome was on fire, I just grabbed a couple of quart size water bottles and put out the flames. Then removed the doghouse, and 'insulation'. At that point, without the Ford factory insulation, it was really hot near my feet. Once back in Kentucky, I bought some header wrap, and insulated the headers where they pass near the doghouse. I also used a paint can lid to reflect away some heat, and retain the insulation between the header and doghouse where they pass each other.

In my motorhome, with a F-53 chassis (97), I have 1/2" thick foam insulation over the carpet in the drivers area. It does stop a lot of heat from going though the floor, and makes the floor much cooler. I know it would be much more effective to install some of that 1.5: air duct insulation, but something I have not gotten around to yet. . . .

Good luck,

Fred.
