insulating trailer walls with finished interior

noob · Apr 22, 2019

I just picked up an 7x22 drive on drive off trailer. I'm going to do a webasto heater in this setup. Only problem is the interior is finished already. Don't want to think of taking the interior walls down as an option. anyone have any ideas for insulating the walls without taking the inner skin off?

None that you would be happy with.

1. Blow in foam which would likely bubble the panels
2. Remove the outer panels :face-icon-small-hap

add a layer of foam board over top of the inside and refinish over top of that.

Short of taking the inner skin out and insulating it, that leaves you with few undesirable options.

If only heating for short periods of time just to take the chill off, maybe you don't need insulation. Just a thought.

I have a 7x29 with a 40k BTU suburban furnace and it does great without insulation.

Have run finished walls and ceiling with and without insulation, different trailers, with heat. No heated floors. Unless you're sleeping in them or running professionally, it's a waste of time and money. And on sunny days, you lose some solar transfer - you now have a big cooler with wheels. Spend the savings on LP.

Even if you are sleeping in it, it won't hurt anything to not have it insulated.

An occasional over night will be just fine.

If you are planning on extended stays, now that is a different story.
