In
our area of the country I don't think a
fully insulated coach is necessary.
To
not insulate the roof and around the front curve would be foolish.
It's so easy to do, you've got a space between the roof sheathing and the ceiling liner you might as well fill it with something useful...insulation.
The rear, you've got enough "Dead Air Spaces" insulating you that its not worth worrying about.
Now for the side walls I just laminate a Foam Backed Rug directly to the side plywood.
The rug is helpful in the rear as well and on the ceiling. It gives things a nice quiet feel.
Is the rug on the side walls as good an insulation as the insulation in the roof?
NO, But is the insulation in the side walls as good as the insulation in the ceiling of your house?
NO.
Is Styrofoam
in the side walls as good as a Foam Backed Rug
on the side walls?
Don't know, nobody has ever done an "R" Value test on Foam Backed Rug.
I know that rug on the walls and ceiling is a finished surface.
And this;
Ever roll your butt against a cold wall?
Won't happen with a Rug on the wall.
Everybody has a different view on this topic.
Happy Trails
