I installed a composite laminate with attached backing and also used a rubber underlayment membrane. There is definitely a moisture break doing it that way but only about .26 R added insulation value. My trailer has an aluminum cladding underneath so I wasn't terribly worried about moisture intruding from below. The underlayment does absorb noise and adds some more cushion to the floor,
Thanks. I kind of figured anything that's 1/8" thick or less would have limited R value, but I had to ask. I think I'll roll some out anyway for the cushion and sound deadening factors.
