Application

Kinetics Noise Controlís premier rollout isolation material (RIM) easily creates an airspace of 25mm to 100mm 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 labour 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.

Successfully installed for years under concrete floors found in mechanical plant rooms, recording studios, cinemas, theatres, bowling alleys and gyms, Kinetics Noise Controlís Model RIM-C System remains the leading formwork technique for isolating concrete slabs in any floor or roof system requiring sound abatement. An original, Model 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:  Model KIP isolators fixed in fiberglass batting, Model PIB Perimeter Isolation Board, spray adhesive, plywood junction plates, polyethylene sheeting and tape, and resilient, non-hardening perimeter sealant.  Model KIP isolators spaced 300mm, 400mm or 600mm 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 Model KIP isolators prespaced is rolled-up and delivered in poly bags along with the specified accessories to the jobsite.


Installation

Installation of Model RIM-C is quick and easy. Decouple the area being treated by installing Perimeter Isolation Board (Model PIB) around the perimeter of the room. Additionally, Model 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 Ė 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 Model RIM-C System requires removing the Model PIB tear strip and sealing the perimeter of the floating floor with resilient, non-hardening caulk.
