Generator box insulation

[davidbrady]

Hi John,

You mention the original sound deadening layers. I have some experience with that because of the hardwood installed in my coach. My coach, like most birds, originally had carpet in the salon - I now have hardwood front to back. When the carpet was removed I also tossed the 50+ lb rubber mat that was placed over the generator area and under the carpet. Well, that mat turns out to be a lead sandwich (rubber/lead/rubber) and it does a good job of damping vibrations. (I kinda miss that mat). So, if in the future you decide to pull out the carpet and install a different floor material you'll probably also remove the rubber mat. (It has to go in order to have a flat floor up front for the new flooring material). Long winded story to say that whatever you use for genny insulation, I'd vote for something that is multi-layer with a mass in the center to dampen vibration. This way you're free to do whatever you wish to with the interior flooring. I don't have a manufacturer in mind, but I'm partial to multi-layer convoluted foams. These are those egg-crate materials. Let's see if we can find one that insulates, absorbs, and dampens. My opinion is that the genny needs to be quiet for those inside the coach as well as for your neighbors outside the coach.
