Acoustic Isolation of Plant Rooms

Plant rooms can be located anywhere in a building with the possibility of causing disturbance to sensitive areas such as bedrooms, offices, boardrooms, operating theatres, or penthouse suites.

A typical plant room may include the machinery for HVAC (Heating, Ventilation, Air Conditioning Systems), back up generators, pumps and potentially other vibration producing equipment too! These heavy-duty machines, by their very nature, produce high levels of noise and vibration.

Vibration Isolation in Plant Rooms

This can lead to problems when this noise leaks into surrounding rooms. Not only will it affect the acoustic comfort of staff working in those rooms (reducing efficiency and causing stress) but it can even damage the building structure! It is for these reasons that it is crucial to install some form of vibration isolation in plant rooms. Mason Industries has developed the very best equipment available for acoustically isolating plant room machinery.

The key to effectively isolating a plant room is to create acoustic barriers between each piece of vibration producing equipment and the main building structure. We would normally use a combination of inertia bases, floating floors, flexible pipe connectors and acoustic hangers. In this manner the vibration causing equipment is isolated from the main building structure, an air gap is created and acoustic soundproofing has been achieved.

Inertia Bases, Floating Floors, Isolation Bearings

To start with we need to isolate the equipment from the floor. The usual procedure for reducing the airborne & structure borne noise and vibration levels is for the plant to be installed on inertia bases or floating floors. Or for really heavy-duty plant we have isolation bearings. Occasionally a piece of machinery may be suspended from above using several acoustic hangers. The idea behind using these methods is two fold, firstly an air gap is created and secondly the rubber or spring element will ‘soak’ up the vibration.

Whether you use LDS rubber (prev neoprene) or a spring element will depend upon the frequency of sound that your plant is producing. For more information on each of these methods and product types, please scroll down the page and click on the appropriate section. Or just contact our acoustic engineers.

Pipes Isolation

Any piping that attaches to vibrating machines will also need to be acoustically isolated, allowing for movement and stress. For this we recommend our flexible pipe connectors and our acoustic hangers. By using this combination of products you ensure that the plant rooms vibration & noise is unable to pass through to the main structure as it is absorbed by the rubber and spring elements of our products.

We have a large range of flexible pipe connectors; ranging from our Kevlar reinforced rubber Safe Flex and Super Flex, to our braided metal, stainless steel and copper pipe connectors. What is used for your plant room equipment will depend upon several variables, and is best discussed with our engineers.

To suspend this piping you will need to use resilient hangers. We have a large range of hangers to suit load and frequency. Typically either LDS rubber or spring elements or a combination of both are used, selected to meet the project specifications.

Typical Products Used

Rubber Expansion Joints

There are many types of flexible pipe connectors and expansion joints produced by Mason Industries. This page gives a brief overview with links to more specific product details.

Spring Mounts

Mason UK has a complete range of spring mounts both open, enclosed and restrained. Spring mounts are typically used for applications where low frequency (sub 8Hz) vibrations are present.

Spring Mounted Inertia Bases

Inertia bases, used in conjunction with the right acoustic isolation system, are the most effective anti-vibration technique for machinery. They can vary from a simple steel frame which allows spring mounts to connect to the equipment, to large concrete filled frames to provide inertial mass.

Spring Hangers

Mason U.K. has a large range of spring hangers available to suit a wide variety of loads and acoustic requirements.

Concrete Floating Floors

Floating floors systems are used for many purposes, predominantly to prevent noise passing through the floor but also to isolate against vibration and impact.
