heat and noise help

I am wanting to add sound proofing and heat shield to floor of my MH. There's to many products out there to choose from. Has anyone done this to their RV? And what did you use ?
  • I used Summit Racing's house brand sound deadener sheets. I removed the dog house, cleaned it very well to help the stuff stick and also tried to get any other places I could reach. I also bought some new black rubber foam weatherstripping at Home Depot to reseal the doghouse. Cut the noise and heat dramatically.

    There are a lot of products out there like Dynamat,acoustic core,and products with lead to deaden sound. These are very expensive. I used a product from HD that was made from jute felt and a reflective thin Al foil on one side. It came in a roll and I bonded it with a contact adhesive (Weldwood). It greatly reduced the engine noise and heat. It was about 3/8 in thick and just bonded it over the existing insulation. I also repaired the seals surrounding the dog house and adjusted the clamps that hold it in place. On long pulls I hear more exhaust noise than engine noise. When I first bought it my foot would get hot on long hills. I have an old 454 eng that makes max torque at 1800 rpms. I don't know how a higher revving V-10 responds to extra insulation but I would imagine it would help greatly also.
