INTRODUCTION 

VIMCO is pleased and excited to release our newest marketing literature: the G-1010 booklet. This booklet provides 

condensed information on our entire range of vibration and noise isolation products. The information includes 

product features, application information, dimensional data and model selection tables. We expect this booklet to be 

an invaluable resource for engineers, representatives, distributors and contractors. 

One new tool that we are introducing in this latest literature is our exclusive isolator 5 star rating system . Vibration 

isolation efficiency is directly related to the amount of deflection (compression) of the isolating element. The isolation 

efficiency chart below illustrates the theoretical relationship between isolation efficiency, disturbing frequency and 

isolator static deflection 

Disturbing frequency is the frequency of vibration produced by an unbalanced, 

rotating or reciprocating movement in mass. 

Natural frequency is the number of complete cycles of oscillation a mass will vibrate 

in a given unit of time if a force displaces it from its equilibrium position and allows it 

to vibrate freely. 

Static deflection is the distance an isolator will deflect under the static or dead weight 

of the equipment. 

Isolation efficiency is the percentage reduction in the amplitude of the transmitted 

mechanical vibration. 

We have classified our range of vibration isolators in 5 category's based on their isolation efficiency as detailed below. 

Each isolator selection table within this catalog indicates the isolator star rating.

Floating Floors 


VIMCO floating floors provide a solution to the problem where the transmission loss of the standard structural floor is not sufficient 

to prevent noise from passing from mechanical rooms to noise-sensitive areas above or below it. Floating floors primarily 

control airborne sound transmissions; they are not intended to be used in place of vibration isolators and/or inertia bases. 

VIMCO floating floors perform acoustically on the same 

principle as a double-glazed window : The separation of the 

masses, with an air gap, gives a much greater transmission 

loss than if the two masses are combined into a continuous 

floor. The "enclosed air cavity" is the primary isolator. 

Vibration Management Corporation prefers and recommends a form-work floating floor construction over the lift slab / jack-up 

system offered by other manufacturers. 

All types of floating floor construction perform the same acoustically as long as the dynamic natural frequency of the isolation 

mount, the air gap, and masses are the same. The choice of construction method therefore depends on economy, reliability, and 

ease of installation. Jack-up system manufacturers generally claim lower installed costs. This cost differential tends to disappear 

though, for larger areas where many equipment are supported on the floor, or where many plinths project through the floating floor 

for equipment, piping support. In both cases the number of canisters has to be increased to provide proper edge and weight 

support. Most jack-up systems are designed for a 4" floating floor, with thicker slabs resulting in higher costs, not only due to 

extensions required on the canisters, but again in causing canister spacing to decrease. The VIMCO form-work system easily 

accommodates thicker floating floors with correct isolator selection. The form-work construction also offers the provision of a 

fiberglass infill which in addition to preventing a sound tunneling effect, provides extra transmission loss. Independent lab tests by 

a competitor show that a 2" air gap with fiberglass infill gives a STC rating increase equivalent to doubling the air gap to 4" !!! 

Materials 

VIMCO's form-work floating floor system 

VIMCO form-work floating floor 

consists of the following materials : 

1. Roll-out isolation material provided with neoprene pads 

2. Closed cell perimeter isolating boards 

3. Plywood / cement board form-work 

4. Polyethylene bond-breaker sheeting 

5. Polyurethane perimeter sealant 

6. Neoprene contact adhesive 

7. Floating floor isolated drains 

8. Neoprene high load pads 

VNRM-xx (xx denotes pad spacing in inches): Roll-out isolation material 

VIMCO roll-out isolation material consists of low-density fiberglass with 2" high, resilient, neoprene isolation pads, embedded at 

24" centers as standard. Closer spacing between pads can be factory installed, or achieved at site using additional high load pads. 

VPPI-xx (xx denotes height in inches): Perimeter isolating boards 

VIMCO incorporates closed cell expanded polyethylene sheets for perimeter isolation. These sheets have excellent weatherresistant 

characteristics and aid in preventing flanking noise along the edges of the floating floor area, by completing the isolation 

of the floating floor from the building structure. 

VNHP : High load pads 

VIMCO provides individual neoprene isolation pads for areas with additional, uneven loading. These pads can be factory installed 

with the roll-out isolation material or can be furnished separately for installation at site, by a VIMCO authorized representative. 

VID-xx (xx denotes drain inlet size in inches): Isolated drains 

VIMCO floating floor isolated drains consist of a two member housing, to drain water from the floating floor down to existing 

drainage piping system, without compromising the structural isolation. 

Ancillary materials : 

Depending on economic considerations, local availability, the following materials may either be supplied by VIMCO or sourced 

by your local VIMCO representative. Materials must however comply to VIMCO specifications to ensure proper installation. 

Plywood / Cement board Neoprene spray adhesive 

Polyethylene sheeting 

Polyurethane sealant 




Air Mounts 


1. Air-cushioned isolation 5. Heavy wall construction 

2. Low natural frequency (3~5 Hz at operating load) 6. High lateral stability 

3. High deflection 7. Low maintenance 

4. Neoprene padded top and bottom base 9. Combined resiliency and air prevents drift or permanent set

Seismic Snubber 


VIMCO model SNB3-3050 is an all-directional (3-axis) device designed to restrain and decelerate motion of resiliently mounted 

equipment resulting from external loads or seismic activity, to acceptable limits. The device consists of interlocking welded steel 

members, separated by a molded neoprene insert. Neoprene element is designed to prevent direct metal to metal contact between 

2 steel members, and provide a minimum of 3/4" snubbing material in all directions. Device is manufactured to allow free 

unrestricted movement of equipment of not less than 1/8", limited to a maximum of 1/4" before coming in to contact with energy 

absorbing neoprene insert. Design also allows for removal of neoprene element for visual inspection and/or replacement.
