    Kinetics RIM’s premier rollout system easily creates an airspace of 1 to 4 inches and incorporates a high-performance resilient decoupler. The isolation material with Model KIP isolators selected and spaced according to design criteria offers major advantages over other systems. Installation labor is substantially reduced, as it is easier to roll out batting with pre-spaced isolators versus measuring for and placing individual isolation mounts. This feature also ensures that the system will reach the high levels of expected performance. This system is designed to meet requirements for; load capacity, natural frequency/pad deflection, and acoustical performance.


    • Can be designed for any load range
    • Easy to create 1-inch, 2-inch, 3-inch, and 4-inch airspaces
    • Fast, simple, inexpensive installation
    • Optional channels or nailers can be used for stiffness and increased airspace

    Wood Floating Floor

    RIM System wood floated floors are ideally suited for dance studios, loft style condominiums, recording studios, and other applications where high performance noise control is required in conjunction with a lower profile, light weight assembly. A RIM System floated wood floor surpasses performance of continuous underlayments due to the airspace and lower natural frequency created by the KIP pads spaced at 12-, 16-, or 24-inches on center. RIM System can be supplied to fit any load condition. In the cases of free weight drops like those seen in fitness centers, please consider that lightweight composite floors can prove insufficient standing up to shock loads. Damage to the lightweight floor and isolators can occur depending on the impact/shock loads. Contact Kinetics for guidance when designing these projects.

    Installation Sequence

    Installation of RIM System for a wood floated floor is similar to that of the isolated concrete slab. Starting with a level subfloor, a 3/8” thick strip of SRP (perimeter isolation board) is adhered to all non-isolated walls (the height of SRP is dictated by the height of the finished floor). The rolls of batting with secured pads are rolled out into place. If heavy point loads exist, individual KIP pads are then placed per submittal drawings. Typically, two layers of 3/4" plywood are laid (seams staggered) over the isolation pads, and the finished floor is installed according to the manufacturer’s instructions. While two layers of 3/4" plywood often proves suitable for most isolated wood floor composites, consider using three layers of plywood, glued and screwed together for added stiffness and mass, which aids in load distribution and noise control. Compare sound test AT001035 with AT001036 and discover how adding mass can boost STC results. The installation is completed by applying acoustical caulking to the top of the SRP board.

    RIM for Concrete Floated Floors

    Successfully installed for years under concrete floors found in mechanical rooms, studios, ballrooms, fitness centers, and theaters, Kinetics Noise Control’s RIM System remains the leading formwork technique for isolating concrete slabs in any floor or roof system requiring sound abatement. An original, RIM System consistently provides continuous, high-performing noise control for critical applications. Our pour-in-place floor isolation system incorporates all critical components needed in a top-performing noise control system including: KIP isolators fixed in fiberglass batting, PIB Perimeter Isolation Board, spray adhesive, plywood junction plates, polyethylene sheeting and tape, and resilient, non-hardening perimeter sealant. KIP isolators spaced 12-, 16-, or 24-inches on center are available in different densities allowing for a multitude of load ranges under a single slab while maintaining a constant natural frequency. Factory-trained sales representatives can help designers determine which system to use based on dead and live load requirements. Kinetics Engineering Group will provide design submittals. The fiberglass batting with KIP isolators prespaced is rolled-up and delivered in poly bags along with the specified accessories to the jobsite.


    • Greater load capacity at a lower cost
    • Can be designed for any load range
    • Easy to create 1", 2", 3", and 4" airspaces
    • Fast, simple, inexpensive installation
    • Factory installation and supervision available
    • RIM System successfully installed for over 45 years
    • Natural Frequency constant over a wide load range

    Installation of RIM is quick and easy. Decouple the area being treated by installing Perimeter Isolation Board (PIB) around the perimeter of the room. Additionally, PIB is used as a resilient break against any other non-isolated elements such as curbs, drains, ductwork, adjacent floors, pipe, and walls. The fiberglass batt with pre-spaced isolation pads is then rolled out over the structural floor. A pouring form is created by placing plywood on top of the isolators, and is held together using junction plates and screws. Two layers of 6-mil poly overlapped and taped at the seams cover the pouring form as temporary waterproofing. Concrete reinforcement is installed and then concrete poured in place. As dictated by the designer, trades can move about the floor to complete work in the space without the concrete having been cured to full strength – the floor is already positioned at final design elevation. There is no worry about keeping the floor clear for a second visit to “lift” the slab by an installation crew. The final installation step of the RIM System requires removing the PIB tear strip and sealing the perimeter of the floating floor with resilient, non-hardening caulk.
