Anyone insulate under driver's and passenger area?

Has anyone added insulation under the driver and passenger area? I have an Itasca Horizon 40AD and would like to install some insulation under the floor and forward of the driver's pedals. An earlier discussion mention Dynamat, an automotive product. Has anyone attempted this?

We recently put some Dynamat hood liner on our dog house cover, it was easy to do. But that was because it was there wasn't any wires or hoses in the way. I think to do what you want to do will be very hard with all the things that will be running along the surface that you want to cover. I don't know if a spray on insulator would work or not, it might make it hard to work on the rv if needed.

I looked at doing underfloor insulation where you ask about....and ended up with insulated carpet approach. I'm very pleased with outcome.

Also did the doghouse with dynamat.

Pubtym,

Thanks for the reply. Most of my heat loss is forward of the driver's pedals. I think I need to insulate on the outside of this area. I don't think carpeting will work in this area.

I once did some winter camping snowmobiling. I put some blankets over the drivers area.

If you needed it all the time maybe something like that could be made for a more appealing look.

I think its doable, but you have to decide if you want to dodge all the wires etc.

I like under the carpet method, even if you have to add additonal carpet(ala mat) and cut around the pedals etc, and it works.

Good Miles

lk23,
I installed .067" Dynamat with a silver heatshield from Summit everywhere under and on the fronside of my engine compartment. It is rated for high heat and was very easy to cut and install, especially with 2 people. I used a .75" foam hood liner by Dynamat on the engine cover. Both were adhesive backed and have stayed in place very well. The improvement in noise and heat reduction was immediately noticed. I have covered out to the windshield and all the way across the frontside of the dash. On the floor I covered out to above the tires and used a heavy coat of undercoating the rest of the way to the sidewall. I covered the heater box to keep the heat from warming the A/C air.
I have a little over $200 in material and it was well worth it.

Davel,

Great answer. Where did you purchase the Dynamat. Do you mean .67" or .067". On my diesel pusher I don't have any high heat issues, just cold air coming through the pedal area while driving. I hope to stick Dynamat on the bare metal outside the pedal box and other places.

West Marine carries a foil backed, self stick,acoustical foam for engine compartment sound and heat suppression. It comes in 1/2 or 1 inch thickness. Warns against installation closer than within 6 inches of the manifold. I don't know how it compares to the Dynamat but you might want to check out your closest marine supply.
