sleeper insulation

While the froth pack would probably be the highest R-value, it would be the most expensive and the most mess. If you do go down that road, just don't underestimate the mess, plan on it being more cost than planned, and probably not turn out nearly as nice as hoped. Dynacore over killmat will probably be the best option, while still allowing a little room under the interior panels to run wiring, etc.

 

What about the fire resistance of each product?.......

 

I have used the froth pack in other trailers for fish houses and that stuff, it is a huge mess but imho I am going to do it on my entire truck this summer, sleeper, cab and underneath the floor on the outside, I have seen both closed cell and open cell used, closed cell is the highest rvalue, open cell is the best at noise resistance, I am using open cell on my truck, lower rvalue but alot better on the noise resistance. The stuff we used on the fish house trailer was closed cell and was farely easy, but that was also wide open, on my sleeper and cab I will make sure I have everything taped off or removed I dont want to get that crap on. I have been inside of a truck an older Pete just like mine that is amazingly quiet inside of it and it made me want to do it this summer. The wiring and stuff to the lights on the back of the sleeper will run through tubes on the outside that I will mount into the frame work of the sleeper, the lest of the wiring and lights in my cab is all custom and will just have to be redone afterwards, the dash will be heavily protected to not let any of that crap get in there

 

I don't want the mess of spraying inside my truck. I've used spray foam in a garage. It was good for the application but I wouldn't want to apply in a sleeper. Not that much surface area and the clean up takes a while. I used this product in the cab, floor and doors. No clean up. No overspray. You can double it up if you want thicker.

 

Yeah I currently got that stuff covering every inch of both cab and sleeper, I thought it was great until I sat inside one with open cell foam done and it changed my mind, that was the quietest truck I had ever been in and it's basically the same thing as mine

 

I was thinking the same thing. Fire resistant material is what I would be considering.

 

I’ve done 4 trucks and sleepers in the past few years never would I entertain the thought of using spray on insulation that’s just a bad idea all the way around at some point it makes it harder to do and unforeseen repairs or up grades to wiring .as it dries. It expands and put pressure on panels and things not to mention the mess you have to deal with
I use to use dynamat or killmatt

 

Ive seen professionals do a whole house in that expanding foam , its all about the applicator or nozzle if you will.
