anyone know anything about this yet? the underfloor stuff with the vinyl moisture barrier?

so, they roll it out, and it takes care of flatness issues? or edge swell? or, height differences? or, what?
looks like another brainchild of some guy at a desk so far to me,,,,anybody here used this yet that can tell us about it?

just another thought also, in crawl spaces or over basements, unfinished or un-condition, you put down a moisture barrier, not retarder, and what will happen later?
you are trapping?

someday, somewhere, class action lawsuits in a few years are going to start against one big "B" company that sold plastic barriers to trap??? under their wood?

Good questions Grumpy, but what happens under a vinyl floor over a wood substrate anyway?

now you know!

Mannington has been selling felt-backed sheet vinyl as high-end underlayment for their floating laminate for a number of years already. It was just a matter of time before they were gonna try and stick something to it. I suppose they figured to let congo be the guinea pig. Guys have been laying ceramic tile on top of loose laid felt paper for it seems like forever.

Just another way to sell more product and get their greedy paws into the installer's pie.

are they saying this takes the place of floor prep?
are they saying put a floating floor over a floating floor or ????

quote:

Congoleum introduced Under-floor, an all-in-one underlayment system for floating installations of DuraCeramic products. “Under-floor is an economical, time-saving alternative to costly underlayment systems,” Anderson said. “This new technology will help take DuraCeramic to the next level.”

Underfloor offers a felt construction coated with a vinyl moisture barrier. It can go over plywood, OSB, particleboard, concrete, gypsum, existing floors like resilient or hardwood, and even old adhesive or paint.

That seems to say its an underlayment option for their fancy vct.

the question I keep coming back to in my small little mind is, should floating be over floating?

Are you asking if this floating system should be installed over an existing floating system?

DuraCeramic is an adhered tile not floating.

so, you glue it down to a floating system? is this that dreaded "slip floor" that caused so much trouble back in the 80s and early 90s????
or, did i just make that up? maybe, maybe not,

so, we put this down, glue the flooring to it, and if there are problems or replacement is wanted, just rip it all easy?

I'm not sure of the product as I have not seen the underlayment. But installing something brittle like duraceramic on top of something you can roll out seems scary.

Lots of nice things about floating floors is being able to go over sutff like old VAT and old adhesives.

I have not seen the underlayment.

It's just a basic 6' wide felt-backed sheet vinyl, no color, pattern, finish or embossing. It's laid out vinyl side down.
