Reduce Floor Noise to a whisper with our line of SSP High Performance Soundproofing Underlayments.

Concerned about reducing impact and acoustical (airborne) sound transmission through hard flooring surfaces?

Eliminating impact and acoustical noise problems between floors in multi-story construction is another sign of a quality installation and a feature that clients, residential and commercial will appreciate. This includes, but is not limited to condominiums, apartments, single family homes, office buildings, RV’s, hotels and schools.

To address these concerns, Super Soundproofing™ offers a line of high performance underlayments that will help reduce floor noise to a whisper. “Super Soundproofing™ offers the installer many benefits with just one product”, notes Super Soundproofings’ General Manager.  And this is one the thinnest sound control products on the market. The line includes:

SSP-TL: for ceramic and natural stone tile
SSP-FL: for engineered hardwood, parquet, and laminate flooring

SSP FL Plus: same qualities as Super Soundproofing™- FL plus protection from subfloor moisture emissions

Super Soundproofing™-TL is a peel-and-stick sheet membrane that reduces impact and airborne sound transmission while isolating finished flooring from subfloor cracks. It is constructed of cross-linked poly-olefin foam sheet combined with an aggressive rubberized adhesive and a polyester mesh fabric. Designed for use with ceramic and natural stone tile, Super Soundproofing™-TL has the flexibility and strength to withstand structural movement and concrete shrinkage cracks up to 1/4″ without transferring stress load to finished tile. It also has superior moisture resistant properties that make it the most comprehensive underlayment product for ceramic and natural stone available. And like its counterparts in the Super Soundproofing™ family, Super Soundproofing™-TL is approved for installation over radiant heated floors.

Super Soundproofing™-FL is a peel-and-stick non-permeable sheet membrane, which reduces impact and airborne sound transmissions and is a moisture/vapor barrier. Designed for use with engineered wood plank, wood parquet and laminate floors, it should be used where sound-control is required, specified, or desired. Super Soundproofing™-FL may be applied to structurally sound and clean surfaces, including: concrete; plywood; precast floor panels; OSB; ceramic tile; terrazzo; natural stone; Portland based leveling and patching compounds; cement backer board; existing VAT; VCT; and fully adhered vinyl floors. Super Soundproofing™ is also approved for installation over radiant heated floors.

Super Soundproofing™- FL’s membrane is tacky on the bottom providing superior adhesion to concrete, steel, and wood substrates. The cross-linked poly-olefin foam top sheet makes an excellent bonding surface for approved wood flooring adhesives and will not dry out or decay with time. It also contains no V.O.C’s and is environmentally safe.

The Super Soundproofing™ FL Plus System not only reduces ambient and impact sound transmission, but also protects wood floors from subfloor moisture emissions that can lead to wood distortion and mold. The Super Soundproofing™ FL Plus Membrane features a 2″ peel-and-stick overlap seaming edge on one side of the sheet that allows for an adhesive-to-adhesive bond between adjoining sheets, creating a monolithic protective membrane across the subfloor.

The Super Soundproofing™ FL Plus System also consists of a Sealer-Primer: a solvent-free, polymer-based moisture emissions reducer and primer. It is designed to seal subfloors that have up to 8 lbs. moisture emissions, reducing the emissions to 3 lbs. or below. The Sealer-Primer also seals porous and dusty surfaces, which improves adhesion spread rates and long-term bond aging. Designed for easy roller application, it forms a tough water resistant film over the substrate surface when applied properly.

The entire Super Soundproofing™ family of high performance underlayments is extremely efficient, economical, and offers ease of application for today’s flooring installation professionals. When sound control, crack suppression, and moisture resistance are your concern, turn to the flooring membrane sound control professionals at Super Soundproofing™.

Compositions and Materials: SSP-FL is constructed of cross-linked poly-olefin foam sheet fused with an aggressive rubberized adhesive. The membrane is tacky on the bottom providing superior adhesion to concrete, steel and wood substrates. The cross-linked poly-olefin foam top sheet makes an excellent bonding surface for approved wood flooring adhesives. Contact us for the approved adhesive list.

SSP-FL contains no V.O.C’s and is environmentally safe. The cross-linked poly-olefin foam and its aggressive rubberized adhesive retain its flexibility throughout the floor’s life span and will not dry out or decay with time.
Size: Available in 36″ x 50′ rolls.

SSP-FL underlayment membrane is designed for sound deadening
under engineered wood plank, wood parquet and laminate floors. It may be applied to structurally sound and clean surfaces including: concrete, plywood, precast floor panels, OSB, Ceramic tile, terrazzo, natural stone, Portland based leveling and patching compounds, cement backer board, existing VAT, VCT and fully adhered vinyl floors. SSP-FL is approved for installation over radiant heated floors.


SSP-FL is not recommended for use on concrete floors where hydrostatic pressure is present or where Moisture Vapor Emissions Rate exceed 4 lbs. SSP-FL cannot maintain the high sound control ratings when used with solid wood plank flooring or any “nail down” only wood floors. Gypsum type patches and levelers are not recommended. Super Soundproofing™ will not accept responsibility for failures related to use of gypsum underlayments or patching compounds. NOTE: Use only approved wood flooring adhesives (Contact us for list). Installation procedures and job site conditions must be in accordance with flooring manufacturer’s recommendations and NWFA installation standards or performance will suffer.

INSTALLATION for Wood Floors

Follow wood flooring manufacturers recommended installation instructions as to fully adhered or floating floor installation

Your wood flooring and SSP-FL membrane must acclimate to job site conditions before installation. Concrete subfloors must be dry, clean and free of dirt, grease, wax, paint, oil or anything that would adversely affect adhesion of the material.

Subfloors must be checked for excessive moisture. If subfloor moisture/
vapor is higher than 4lb. Emissions, SSP-FL membrane cannot be used (see “Limitations”). Subfloors must be flat to 3/16″ in a 10′ radius. Leveling cements must be completely dry before membrane application.

Priming the subfloor: Always apply the Super Soundproofing™ primer to the subfloor and allow to dry (approx 20-30 min.) before installing the SSP-FL to ensure a good bond.

Unroll SSP-FL with the release liner side down. Cut the length approximately 12″ longer than the distance to be covered to allow for a trimmed fit. Fold back half of the length of the roll back over the other half of the material. Score through the release liner only, taking care not to cut completely through membrane. Pull release liner away from membrane where scored. As the release liner is pulled away, hand-smooth the membrane to contact the primed subfloor. Keep the release liner material close to the floor while pulling away, this will allow for a more controlled application of the membrane.

Take note: there will be an immediate and aggressive bond of the membrane to the primed subfloor. Realignment of the membrane can be difficult once adhered to the subfloor. Waterproofing Applications: Installations requiring waterproofing characteristics must have a topical application of liquid anti-fracture and waterproofing membrane at the seams of the SSP-FL. Using a 3/8″ nap paint roller, apply a liberal thickness, 6″ wide layer of the liquid membrane over the seam (3″ of liquid membrane to overlap onto both sides of where the edges of the SSP-FL meet.) Be sure to have the seam completely covered with liquid membrane with no gaps. Allow the liquid membrane to cure fully before installing the wood flooring.

Approved Wood Adhesives: Approved wood flooring adhesives work well. Most latex and acrylic based wood floor adhesives which are compatible with foam sheeting are approved. Contact Super Soundproofing™ for approved adhesive list. Super Soundproofing™ is not liable for failures due to use of unapproved adhesives. (Solvent based adhesives and most urethane adhesives are not compatible with SSP-FL. Some water-based adhesives do not bond sufficiently to the membrane surface.) Spread the approved adhesive onto the adhered membrane in accordance with manufacturer’s recommendations for trowel size and open time. Adhesive flash time may be longer when used over SSP-FL than over concrete or wood subfloors due to the membrane’s non-porous construction. Continue to follow wood flooring manufacturer€™s installation recommendations through the remainder of the flooring installation.
