The Isolation Clip is used in new or existing wall and ceiling constructions to isolate the gypsum board from the framing. Clips are fastened directly to wood, steel, or aluminum studs and are designed to accept standard drywall furring channel. By breaking the mechanical connection between the isolated gypsum board and the other side of the wall or floor assembly, structure-borne noise is prevented from travelling between the two spaces. This has been acoustically tested to add 15 to 20 STC or IIC points to an existing assembly. For the applications with stringent noise requirements, isolation clips should be used in conjunction with Roxul AFB® and TuffMass-UL. The rubber bushing of clips allows for easy screw fastening into wood or metal framing as well as into concrete substrates. With the clips fastened in place, standard drywall furring channel (hat track) is snapped into the clip, and gypsum board is hung using screws per standard practice.

SpecificationsFire Resistant Promat's Promarine panels provide both thermal and acoustic insulation.

Floated Bulkheads, or even an entire floating interior, can have a significant effect on noise reduction, essentially turning your floor into a layered sound absorber. Floating a bulkhead means adding layers - hard surfaces raised or suspended with small fasteners, creating a thin, absorbent layer of either material or air in addition to the standard bulkhead. This approach is often used in staterooms, but it can also work in the engine space if there is enough clearance.

Isolate your interior spaces by decoupling the floors and walls from the structure of the vessel to keep structureborne vibrations from traveling through the hull. Floated soles are especially useful for staterooms, and can quiet a noisy space.
