I am going to start building a box to install my gen set in. I have the specs as to the size and I will be using fire retardent insulation. My question is has anyone used wood to line the inside of their box and what are the chances of it catching on fire. What is a good material to use to build a box. I don't have any room on the inside of the old A/C compartment so it will be a 3 sided compartment with the top insulated as well. I am istalling it where the A/C condesor was on my MC9 Thanks in advance | ||

Grant...I decided to use Hardy Board (sp) covered with fire retardant insulation... the kind used in automotive applications. Comes by the 5 foot roll, as I recall; about 36 inches wide or so. The edges are covered with Aluminum Channel....5 years later, no problems. "hooked" together in a couple of ways. Quiet, easy to build...easy to remove and re-install. Do it Ur way, as FF says...

http://www.soundown.com/S101.htm Ain't cheap but its probably the best in world. The 2 inch thick, 2lb lead sheet inside is grand!!! An OK place for " Bestitis". Your neighbors will think so , forever. FF | ||

I used SounDown's 2" 2# ft/sg fibreglass /lead sandwich material for the engine compartment (doghouse) on our 1983 forward control Wanderlodge. It really made a huge difference. I also put down their 2# ft/sq 1/2" thick rubber/foam sandwich sub floor and installed Dupont engineered flooring above. Very happy with results. My next project is the generator compartment. SounDown is recommending an adhesive damping material against the generator compartment surfaces and their 2# ft/sq composite material with decoupler over the damping sheet. As with the doghouse material, mechanical fasteners are required to keep this stuff in place. The fasteners are aluminum spikes with a perforated base about 2" square and these are mounted with structural epoxy. After these are mounted you press the sheeting over this (even the adhesive stuff), cut them to length, apply lock washer and then a finish cap. Gary Kissal is the rep I worked with there. Although this company caters to the high end Yacht crowed, he was genuinely interested in helping me with my low end bus project and the cost was not outrageous. I am only a satisfied customer and no other interest for making this endorsement. Here is Gary's e-mail address gkissal@soundown.com Bill | ||

I'm going to do the same thing soon. RCB - I beleive there are two kinds of hardy board, one is a concrete with fiber, the other is some kind of hard, but much lighter non-concrete. Which did you use? I am thinking the "mass" of the concrete board would deaden sound better. Jim | ||

Jim...I used the only Hardy that I have seen. A dense cream colored product purchased at Lowes. 1/2 in thick...I think there is also a 3/8 inch board. Haven't seen a thicker one. The other that I am familiar with is Duroc.. a cement/fiberglass "crumbly" board...fine for underlayment, but IMHO not suitable for a high heat "box". FWIW RCB |
