Laboratory and in-field acoustic test data

The IAC Acoustics soundproof doorset range covers a wide variety of performance levels between Rw50dB and Rw63dB, and beyond with custom configurations.

The complete doorset assemblies are regularly tested in laboratories and in-field for the purposes of continuous qualification, product development and to ensure we uphold the IAC Acoustics guaranteed in-field performance.

Our professional team ensures that your complete assembly is installed in accordance with our strict compliance standards.  This mitigates any localised acoustic flanking issues within the doorset and host wall arrangement, ensuring the acoustic doorset performance your project specifies is delivered with the highest quality fit and finish.

Construction

Engineered, manufactured and factory assembled advantages

Studioa

All IAC Acoustic doorsets ranging from small hatches, to single, double and large double doors, are designed, engineered and manufactured to rigid acoustic and safety standards as part of our ISO9001 compliance certification.

AutoCAD and SolidWorks models of our doors are pre-programmed for manufacturing efficiency.  Sheet steel is laser cut to the precise tolerances required for high performance acoustic doorset manufacture and then folded for onward assembly.

Our standard range of door hardware is pre-configured into the manufacturing system, enabling the cut-outs and internal fixtures and assembly requirements to be integrated and detailed in the initial production process.

This means that there is no requirement for cutting, drilling or access to the internals of the door and frame after the paint finish is applied.

Once the doorset has been through the polyester powder coating line, there is no risk of damage with every cut-out, hole and exact hardware item perfectly positioned and ready to be fitted in a rapid assembly schedule.

All doors are then fitted to their specific door frames, and tested for operation fit, alignment and acoustic sealing – additionally all door hardware items are checked for operation including mechanical and electrical components, from door handles and door closers, to electric strikes and access control systems.

This process ensures that the exact doorset your project specified is delivered and installed to site with a guarantee of acoustic and operational performance.  We believe we have the best acoustic doorset in the global market – as our existing customers with over 1 million doorsets installed, will attest to.

Product Certification

Testing and compliance

Noise-Lock D-59 Acoustic Doorsets - Lorient, UK

Alongside laboratory and in-field acoustic testing of doorsets, IAC Acoustics offers other mandatory certifications for both Fire Rated Acoustic Doorsets and CE Marking compliance, where appropriate.

IAC Acoustics offers a range of acoustic doorset products to BS476-22:1987 with further testing in process to the EN 1634-1 standard.  Fire Standards are complex with performance measurement for overall Integrity and Insulation characteristics. This is applied alongside varied scope for the practical Field of Application of single and double doorsets, with acceptable design configurations.

Our soundproof doorsets are available generally with an E60 / FD60 marking, with options available through to E120 / FD120 in specified sizes and configurations.  These options can include fire rated vision panels and specialist hardware for access control and escape functions.

Due to the complexity involved, we highly recommend consulting with one of our Door Team experts for your specification requirements.

Subsequently whether the proposed doorset is fire rated or non fire rated, and whether an internal or external doorset, it may also require CE Marking,

An outline of the scope of certification requirements for CE Marking is available from the Door & Hardware Federation, among other sources.  Some key requirements summarised below;

How to select the right Acoustic Doorset for your project?

Although the acoustic headline data of Rw50dB to Rw63dB product range gives an indication of the calculated overall performance, projects typically require a more detailed acoustic analysis to select the correct doorset to achieve the clients’ noise control needs and meet their performance expectations.

The range of IAC Acoustics soundproof doorsets are manufactured with specific considerations to different frequency bands – something particularly important at specification stage if your project is targeting a recognised noise control requirement or octave frequency band – whether its low or high frequency, human voice or loud industrial machinery for Noise at Work compliance.  An example could be the requirement to control the 100Hz hum from an electricity transformer – this low frequency noise source will require a higher mass of doorset for effective noise control.

To meet a wide spectrum of noise control performance requirements our Noise-Lock® architectural acoustic doorset construction ranges from a base 64mm leaf and matching frame with twin high performance self-aligning magnetic acoustic seals, through to a 128mm leaf and matching frame with triple high performance self-aligning magnetic acoustic seals.

Similarly our Super Noise-Lock® large industrial acoustic doorset construction ranges from 100mm leaf and frame with twin compression acoustic seals, to a 150mm leaf and frame with triple compression acoustic seals.

You can view our technical data sheets for Noise-Lock® acoustic doorsets  Super Noise-Lock® acoustic doorsets.  These will give you initial data and insight to the different acoustic performance characteristics to guide you on product selection for your project.

 

What makes a high performance acoustic doorset?

As our world becomes more populated and condensed, acoustics and legislation becomes increasingly evident to protect us from the impacts - we need high performance acoustic doorset solutions for effective noise control.

Best Practice

Design considerations

As our environment and the general built environment becomes more populated and condensed, noise control and its associated legislation becomes increasingly evident as part of the protection strategy for mitigating the impact to humans.

There are many legislative standards to consider, in particular IAC Acoustic soundproof doorsets are commonly used for noise control in four main areas;

There are of course many other core legislative standards across the industry sectors we provide acoustic doorset solutions for, such as audiology and acoustic test facilities.
