Sound proofing Dog House?

I had the dog house off to change the oil on my coach. (see ďOil Change 2018 Vegas) I had some extra expanding foam sealant (see Sealing Under Carriage), so I decided to spray the interior portion of my Dog House. It will probably keep the heat down also

How did it work out? Did it help with heat and sound?

Dog house insulation...plus floor

I removed the seats of our Class C 31W (4 nuts and bolts per) and the doghouse. Then used race car grade thermal insulation (double faced aluminum foil with air filled pvc between the aluminum). Using a high strength 3M adhesive I first cut out and shaped the insulation for the doghouse then applied the 1/4 inch thick insulation to the engine side of the doghouse. I pulled the rubber floor mat and added insulation to the entire floor with a double layer over the rear engine, transmission, drivetrain area.

Result.. way less heat and road noise. Cost about $50 and a few hours of my time. I would consider this a low to medium skill level of DIY project. The wife is more comfortable and the dogs donít get hot foot anymore

I havenít driven it since insulation. I agree this is low level DIY, however, it was an afterthought trying to use extra expansion foam after undercarriage holes were sealed.

Good idea! I was just sharing a different approach. Seems our manufacturing friends enjoy lots of doodahs in the coach but overlook the basics...

Sound proofing Dog House?

I am absolutely amazed at how well this cheap modification worked! The sound reduction is wonderful. My wife and I are able to speak at near normal conversational levels. After 5 hours of driving, the heat reduction is incredible. The top horizontal portion of the doghouse is barely above room temperature and the vertical sides of it are at room temperature. I highly recommend going through the hassle of making this modification!
