American Flooring Distributors supplies Proflex RCU-250 in New York, California, Massachusetts and Connecticut. RCU-250 is an advanced composite sound control underlayment utilizing a combination of natural and engineered products to achieve superior IIC (Impact Insulation Class) and STC (Sound Transmission Class) sound reduction ratings. The product is also easy to install using a direct bond method, and is compati- ble with a variety of substrates and adhesives (See Installation Instructions for specific information)
FEATURES AND BENEFITS
Proflex RCU-250 offers an industry leading sound reduction in a single layer membrane product. RCU prod- ucts typically meet or exceed most community building code, developer, or condominium requirements. The product also installs quickly and minimizes transition issues. In addition to the sound benefits. The product has been engineered and produced in a manor that meets several criteria supporting green / environmental building requirements. Using RCU products will assist a builder in qualifying for LEEDTM Green Building Rating System in the following areas:
- MR 4.1 5% Recycled Content of total building materials (post consumer + 1/2 of post industrial)
- MR 4.2 10% Recycled Content of total building materials (post consumer + 1/2 of post industrial)
(RCU products are approximately 80% post consumer and 10% postindustrial recycled content by weight)
- MR6 Specifying rapidly renewable building materials for 5% of total building materials (RCU products are approximately 10% rapidly renewing content by weight)
- EQ 4.1 Low Emitting Materials, Adhesives, and Sealants (Adhesives Specified meet SCAQMD Rule 1168)

Proflex™ RCU membranes, when properly installed in accordance with the following installation guidelines, will provide years of protection for finish flooring installations. In addition to these instructions, installers shall also refer to the most current edition of the following publications: American National Standards Institute (ANSI) publications, Tile Council of America (TCA) Handbook for Ceramic Tile Installations, The Marble Institute of America (MIA) Dimen- sion Stone Design Manual. Manufacturers instructions of selected setting materials, substrates, sub-floors, or other manufacturers being used in the total, or any part of, an installed flooring system with Proflex™ consult your select- ed manufacturer of these above mentioned components to ensure selected products are compatible with Proflex™ RCU membranes. Or visit our website at www.proflex.us and click to our link listing our approved setting materials that have been approved for use with Proflex™.
Surface Preparation of selected substrates: Concrete shall be in place a minimum of 28 days. Concrete shall be in- stalled in compliance with industry standards and concrete manufacturer’s instructions. The surface shall have a smooth finish and be free from voids, sharp protrusions, and loose aggregate. Substrate temperatures should be between 50°F and 75°F. Concrete shall be structurally sound, dry, clean, and free of dirt, oils, grease, loose peeling paint, concrete sealers or curing compounds, cement laitance, and other similar bond inhibiting materials. Rough or uneven surfaces should be made smooth with a Latex Portland cement underlayment to provide a smooth and acceptable finish. Do not level with asphalt-based products. Concrete should be tested for moisture vapor transmission by use of a Calcium-Chloride (CaCl) test. Consult technical support if test readings indicate a reading greater than 5# per 1000 sq. ft/24 hours. Plywood must be a minimum of two (2) layers 5/8” exterior grade plywood. Plywood shall be securely fastened in accordance with industry standards as listed. Maintain 1/8” gap between plywood sheets and all surfaces they abut. Joints in the top layer should be offset from the joints on the bottom layer. It is the responsibility of the installer to verify the deflection of the floor structure and sub-floor does not exceed L/360 of the span under combined live or dead loads.
Perimeter Isolation Strip Install the precut 3/4” wide, 6mm thick perimeter isolation barrier vertically around the perimeter of the entire floor including any openings or protrusions such as electrical boxes, heating ducts, cold air re- turns, columns or pipes in the sub-floor installation. The perimeter isolation strip MUST be installed prior to Proflex™ RCU products being installed. Remove the release liner from the self-adhesive backing and place flat against the wall, flush to the floor. After positioning, press the isolation barrier firmly into place at all wall and vertical partitions surrounding the perimeter. Never mechanically fasten the isolation barrier, this will severely diminish the acoustical performance of the entire sound rated floor system. After the finished floor is installed, barrier should be trimmed flush with the surface of the finished floor.
Adhesive Application Use the appropriate notched trowel to ensure 100% coverage of the backing of the Proflex™ RCU underlayment being used. Install the RCU underlayment into the adhesive while the adhesive is still fresh. The Proflex™ RCU products, like other non-porous backed material and stiffer materials with an inherent memory, may require the installer to allow 10-15 minutes of drying time (dependent on temperature and moisture conditions) for the spread adhesive to tack up before setting the underlayment. Proper adhesive transfer to the backing should be checked periodically.
Application for direct bonded tile flooring Cut the RCU material to the desired length and position the material in the space to be covered. Butt the RCU material against the perimeter isolation barrier already installed at the floor/ wall junction. Pull the loose laid material back at least half the length of the cut material. Using a properly sized trowel to apply Proflex™ RCU-Adhesive. Gently place rolled back section into the bed of adhesive and imbed it into the adhesive. Repeat the process for the other half of the sheet, making sure there is 100% adhesive coverage on the sub-floor. Use a 75 # roller in both directions to remove any air pockets.
Application for direct bonded wood flooring Cut the RCU material to the desired length and position the material in the space to be covered. Butt the RCU material against the perimeter isolation barrier already installed at the floor/ wall junction. Pull the loose laid material back at least half the length of the cut material. Using a properly sized trowel to apply Proflex™ PWA 200 urethane adhesive. Gently place rolled back section into the bed of adhesive and imbed it into the adhesive. Repeat the process for the other half of the sheet, making sure there is 100% adhesive coverage on the sub-floor. Use a 75 # roller in both directions to remove any air pockets.
Setting Materials ONLY PROFLEX™ APPROVED MORTARS AND ADHESIVES ARE TO BE USED WITH PROFLEX™ RCU
MEMBRANES. Contact Proflex™ for mortar / adhesive suitability and approval for use with Proflex™ RCU mem- branes PRIOR TO INSTALLATION. NON-APPROVED MORTARS AND ADHESIVES USED TO INSTALL FINISH SURFAC-
ES OVER PROFLEX™ RCU MEMBRANES WILL VOID WARRANTY Use appropriate notched trowel for application of setting materials in compliance with ANSI, TCNA, MIA, NWFA, and these installation instructions. Visit our website at www.proflex.us and click to our link listing setting materials that have been approved for use with Proflex™ RCU membranes.
Finish Surface Installation Apply finish flooring in compliance with the finish manufacturers instructions, mortar / adhesive manufacturers instructions, and the publications listed in paragraph 1 of these instructions. Do not install any defective, damaged, or any finish flooring surface not for its intended use. The installation of this product does not eliminate the need for movement joints, including perimeter joints with a tiled surface. Perimeter expansion of
¼” must be maintained at all times. Consult the TCNA handbook for other movement joint applications. The product is not for use over expansion joints, or structural (out –of –plane) movement cracks. Impervious tile (less than 0.5% absorption) may require a 48-hour cure prior to grouting. The mortar will be sandwiched between two non- absorptive materials, and may require additional curing time.
CAUTION: EYE AND SKIN IRRITANT. Wear protective clothing when applying product. Consult Material Safety Data Sheet for handling and disposal. Keep this product out of the reach of children and pets.
