Product Details

Aquabar "B" floor and tile underlayment is an extremely effective moisture vapor retarder for use in a variety of interior construction applications. Consisting of two layers of Kraft paper laminated with asphalt, Aquabar "B" is a non-reinforced 30/30/30 duplex type Grade "B" paper. In the battle against interior moisture damage, the best defense is a strong offense. When you block moisture vapor from creeping underneath finish materials or reaching moisture sensitive substrates, you help increase the useful life and appearance of surface finishes. To help win the battle, the Fortifiber Building Systems Group offers Aquabar "B" as a great tile underlayment and inexpensive insurance to reduce moisture-related problems.
  • Ideal underlayment for interior installations of: ceramic, porcelain or stone over cement board, plywood or concrete; and, finished or unfinished wood floors over plywood or concrete
  • Most commonly used beneath wood flooring, ceramic tile and stone veneer or as a membrane on walls, counter tops, and residential showers
  • Sub-floor barrier slows moisture migration and helps prevent buckling, cupping, and cracking
  • An extremely effective moisture vapor retarder for use in a variety of interior construction applications
  • Acts as a slipsheet to minimize dust and reduce noise
  • Meets CA01350 indoor air quality standards
  • 500 sq. ft. roll measuring 3 ft. x 167 ft.

            Creased and Delaminated
            I bought two rolls of this for a nail-down hardwood floor installation. The first strip went down fine. However, when I rolled out the second row, I noticed that the product had lots of creases toward the center of the roll (presumably because the manufacturer doesn't use a rigid cardboard core to save money). What's worse is that the layers delaminated where the product was creased. This caused the product to make a loud crackling noise when stepping on the delaminated area. Horrible!

              Great product, definitely use it for hardwood floor underlayment, but.. the last 25% is wavy and creased at the end of the roll, to the point you can't use it. It's a stupid packaging design that makes this great product so-so

                Fortifiber was used in the dining room, rolled out onto a plywood subfloor that was directly above our "dry" basement. We used stapled down manufactured wood for the flooring. The Fortifiber rolled out easily, was tough enough to walk on and arrange the flooring on, made the floor quiet and did not rip. The Fortifiber was left out of the plastic shipping bag for 2 weeks before we used it and there was no strong asphalt smell then or now. Great product.

                It's not what in the specification. It's only <7 mil, not claimed 12 mil!
                Ordered online according to the specification. However, 7 mil is far away from 12 mil. It will be returned tomorrow to the store.

                  Great product
                  Used this product on top of plywood. This priduct made laying the flooring very easy. Stayed in place once it was rolled onto the plywood. Did not use anything to hold in place. I will use throughout the whole house. I will recommend this product.

                    Great, thin underlayment for hardwood flooring installations. Provides a smooth, clean surface as well as allowing for normal movement of the flooring.

                    Worked great! Use under Bamboo hardwood, just rolled out and cut. Did not staple, just put hardwood down right on top. Also used it to put under hardwood and tread nose that I was gluing to make my own hardwood stair treads. The Aquabar kept the glue squeeze out from sticking to the plywood that I was making my stair tread on.
