Protect your team from excess noise

The Control of Noise at Work Regulations 2005 (Noise Regulations 2005) require employers to prevent or reduce risks to health and safety from exposure to noise at work. Employees have duties under the regulations too.

Here at Cammach Industries, we work with client companies to ensure that they are complying with the regulations and protecting their teams from risks connected with excessive noise.

We welcome enquiries, so please feel free to contact the team to discuss your situation. We will be happy to work with you and effect a practical solution to your problems.

The Regulations require employers to:

  • Assess the risks to your employees from noise at work.
  • Take action to reduce the noise exposure that produces all identified risks.
  • Provide your employees with hearing protection if you cannot reduce the noise exposure enough by using other methods.
  • Make sure the legal limits on noise exposure are not exceeded.
  • Provide your employees with information, instruction and training.
  • Carry out health surveillance where there is a risk to health.

Working with you to protect your team

Working in conjunction with leading UK academic institutes, further research and modelling packages can be offered for high value projects where complete quality assurance is required.

Typical projects comprise:

  • Noise survey / noise at work assessment.
  • Deck vent silencers: fabricated from stainless steel to individual requirements.
  • Soundproof enclosures: built to project requirements.
  • Soundproofing of dog house, engine rooms and compressor rooms.
  • High temperature specialist insulation.
  • Acoustic louvers.

Completed Projects

Some of our recent work includes:

  • Engine room silencing.
  • HPU silencing.
  • Deck vent silencing.
  • Accommodation cabin silencing.
  • Workshop silencing.
  • Dog house silencing.
  • Diesel generator container.
  • Carboard factory production line.

Specialist acoustic products:

    HUSH lag

    Consisting of a three part laminate sandwich of glass, mineral wood and a polymeric barrier, this product provides a strong and resilient solution ideal for a wide variety of applications.

    The product can be customised for individual requirements, by finishing in a variety of materials from aluminium foil to perforated PVC.

    This product can also be installed in conjunction with our sheeting to further improve sound reduction.

    Quiet curtain

    A development of our HUSH Lag, this has been designed as an easily installed solution for areas which require flexible easy access, such as pump and HPU skids ie, where all around access is required and fixed acoustic panels are not practical.

    The quiet curtain typically consists of strips 600mm wide with silicone glass cloth outer and silicone glass screen cloth inner. This arrangement encapsulates our HUSH lag to produce a highly effective and practical product which can be used in a wide range of situations.

    Engine and exhaust wrap

    Designed to provide an easily fitted thermal and acoustic wrap for diesel exhausts and other hot vessels, withstanding 1000ºC continuously.

    Consisting of highly efficient needle mat insulation encased in silicon glass cloth, it is made in our sewing room to suit all your requirements.

    The advanced specification of this product allows for a thinner than normal insulation thickness in comparison to traditional materials.

    Deck vent silencing

    The effect of duct silencers fitted on the deck is to achieve a sound barrier between the machinery space below deck and the above deck areas. This effectively reduces transmission of fan noise from below deck and also reduces noise transmission through the duct.

    Acoustically improved fans and ductwork on the main deck reduce the amount of high frequency noise and create a better working environment. 

    Axial fans tend to emit quite large levels of high frequency noise. The most economic solution to reduce the noise is to add an additional silencer if needed. Cammach’s standard range of circular silencers consist of CDA (straight through type, no pod) and CDAP (podded type). These are available in various lengths and manufacturing materials.

    Acoustic materials

    ACOUSTIC FOAM

    Common applications include: internal lining of ductwork and ventilation equipment, spatial absorbers, absorption linings in marine craft, automotive vehicles, generators, compressors, process plant and electrical equipment.

    BARRIER LAG

    Designed to improve the sound insulation of existing panels of metal, wood, plastic etc, at all frequencies. The mat is normally fixed in intimate contact with the original panel. Barriers are particularly effective in overcoming coincidence dip resonance found in stiff lightweight composites such as plywood sheets and hollow core panels

    FOAM LAMINATES

    Ideally suited for ductwork, infills for partitions and baffles between offices, enclosures, refrigeration and compressors, and anywhere considerable reduction of noise breakout is required.

    HUSH LAG P

    Applications include vehicle engine compartment lining, complex jacketing of pumps and similar items of plant, fan jackets, removable pipe and duct lagging, acoustic screens, ship and boat engine room insulation, offshore oil rig equipment, compressor and turbine insulation etc.

    HUSH LAG H

    HUSH H differs from HUSH P due to the fact that foam is used instead of quilted fibre. This means that if an application is required in a clean room environment and must be kept fibre free then Muftilag H should be used.

    MELAMINE FOAM

    This product is used in various applications, including marine, construction, H&V, Internal lining of ductwork, absorbent wall / ceiling panels (See Quietwall Panels).

    QUIETWALL PANELS

    Providing an atmosphere of privacy and comfort, Cammach has developed Quietwall, a range of acoustic wall panels specifically designed to absorb unwanted sound.

    REINFORCED VINYL

    Reinforced vinyl is widely used to prevent moisture and water ingress. With its hard wearing and wipe clean surface, the product is ideally suited in hygienic type applications.

    ROCK LAMELLA

    Ideally suited to limit noise breakout from pipework and soil pipes. The product is a laminate consisting of Class O foil facing, acoustic foam 5kg or 10kg barrier mass, and an acoustic foam space layer.

    ROOM WALL LINER

    Manufactured from 80kg rock and encapsulated with either black or white 200grm glass cloth with a Class O foil backing. The product provides an effective means of controlling reverberation time and reflective sound within plant room type applications.

    SEWING SHOP

    Our sewing shop is able to offer a wide range of bespoke acoustic products including fan jackets, pipe wraps, exhaust shrouds and acoustic curtains. Whatever your requirement, just ask. Cammach will be happy to help.

    SPECIAL PRODUCTS

Whatever your particular requirements, Cammach can help.

    TAP TILES

    Taptiles are a multi-layered composite, and are widely used for noise control purposes in a variety of applications. They are ideally suited for recording studios and cinema type applications The range of semi-rigid and rigid sheets are laminated and combined with a polymeric barrier, which is available in weights of 5, 10 or 15 kilo.

    TAPWRAP
