Vibro-Acoustics Floating Floor System

Floating Floor parts

HIGH SOUND TRANSMISSION LOSS CONSTRUCTION SAVES WEIGHT AND SPACE

Composite construction increases sound transmission loss (STL). STL is increased by the addition of mass to the building walls and floors. This can necessitate a more costly support structure. However, the correct application of double walls and floors separated by an air space, designed against flanking, isolated and impervious to air flow, can result in greater STL than a single barrier of equal mass. The composite construction of a Vibro-Acoustics’ floating floor system with a 4” floating slab supported by 2” isolation pads and mounted on a 6” structuraly slab far exceeds the noise reduction across a heavier 18” structural slab alone. This equates to a height savings of 6” and a substantial weight savings.

APPLICATION

Floating floors are used to reduce noise between an offending space and noise-sensitive areas. Applications for floating floors include mechanical rooms, symphony halls, opera halls, theaters, gymnasiums, squash courts, condominiums, apartments, recording studios, auditoria, libraries, galleries, music rooms plus any application that requires transmission of sound.

VERSATILITY

Vibro-Acoustics meets customers’ needs through providing a variety of options when choosing isolation materials, type of system and the form of installation.

FLOATING CONCRETE FLOOR FORM WORK SYSTEM

Floating Floor Schematic 1Vibro-Acoustics’ concrete floating floor formwork system consists of engineered isolation pads, perimeter isolation board, form work, polyethylene waterproofing sheet and optional fiberglass blanket.

Vibro-Acoustics will furnish design, supply of materials and execute the installation including coordination with other trades. This ensures that work is performed in accordance with the floating floor system requirements.














FLOATING CONCRETE FLOOR JACK-UP SYSTEM

Floating Floor Schematic 2The jack-up system consists of isolators contained within housings complete with lifing bolt, perimeter isolation and polyethylene bond breaker. As with the form work system, Vibro-Acoustics will take responsibility for the design, supply of materials and execution of installation. Prior to positioning of the isolator and housing, as per the approved shop drawings, two layers of polyethylene are placed over the floor to act as a bond breaker. The housings are placed in accordance with Vibro-Acoustics’ design and reinforcing rods are installed. Once the perimeter isolation is in place, the concrete is poured and allowed to cure. The concrete slab is then raised to its operating height by turning the lifting bolts in sequence. Once the floor is raised, the bolt holes are grouted and the perimeter and penetrations are caulked.





INSTALLATION: SINGLE SOURCE RESPONSIBILITY

Floating floor installationThe success of the project is as much dependent on the quality of installation as the accuracy of design. Vibro-Acoustics prefers to be responsible for the installation of it’s floating floor systems. However, a variety of levels of involvement are available to suite the project needs.










BROADCAST CENTRE

Broadcast CentreVibro-Acoustics accepted single source responsibility for the supply and installation of floating floors for the 160 noise sensitive spaces totaling over 130,000 square feet. These spaces required a variety of NC levels ranging from NC-12 to NC-45. Slab thicknesses were designed for 4” to 8 3/4” while special shims were used to create 2” to 4” air gaps. These spaces included radio studios, control rooms, television audio control rooms, television production studios, rehearsal halls and mechanical rooms. Floor systems were engineered to suit the design using formwork systems and our jack-up system. Extensive third party quality control testing was done to ensure the isolation materials met the stringent specifications of the project.




HEALTH CARE FACILITY

Health Care FacilityEight mechanical room floating floors totaled 45,000 square feet. To facilitate the schedule needs of the customer, a large onsite inventory of isolators was shipped prior to the start of engineering drawings. The contractor was able to draw from this inventory as his charging installation schedules and area priorities demanded.
