UKAS Accredited Sound Insulation Testing

Need to get your new build or converted flats and houses signed off by Building Control?

Trust an established, UKAS accredited, Constructionline Gold company to provide sound testing and documentation.

Air Leakage Testing offers a hassle-free route to compliance with acoustic requirements for buildings. As a Constructionline Gold company, you can trust us to provide efficient, high-quality services.

We are a UKAS accredited testing organisation for Approved Document E sound testing. You can trust that the results you receive are correct and will be accepted by Building Control.

Need a quick turnaround?

 

Our team of accredited and experienced test engineers provide a quick turnaround at competitive prices.

 

We can be on-site in a week of your sound insulation testing enquiry. If the transmission of noise through the walls and/or floors are within the defined limits, we will issue certificates the next day.

Need Technical Advice on Sound Testing?

On larger developments, multiple sound insulation tests can be carried out in a single visit or we are equipped to undertake Sound, Air Tightness and Ventilation testing on a single visit. Either option means less disruption and lower costs.

 

Our test engineers are based across the South East so are conveniently located to work with builders and developers across the Home Counties and London. Let us help you to get your properties on the market.

What if a Building Fails a Sound Insulation Test?

It is rare for a new build property to fail to meet the acceptable levels of sound insulation but, if there is an issue, we will share our findings and put you in touch with an independent acoustic consultant. They will advise on ways to address the issue. Re-testing can then be arranged.

How it works

We provide a quote based on the number of units and sampling prescribed by Approved Document E – it is usually helpful to have PDF Plans to confirm the layout of party walls and/or floors relative to habitable spaces.

We provide a checklist, agree on a date and call you ahead of the test date to talk you through the process and the timings.

We conduct the testing.

  • Airborne tests involve creating noise of a known level (approximately 100dB) on one side of the party/separating wall/floor and measuring the volume on the other side to calculate the amount of noise that the wall or floor is insulating. Measurements are taken in multiple planes and positions, reverberation (echo) and background noise are taken into account. The result is expressed in decibels (dB) as DnTw with corrections including traffic noise (Ctr).
  • Impact testing is done using a tapping machine that simulates footfall on the uncovered floor surface. The level of noise is measured in the unit below and the result is expressed in dB as LnT.
  • New flats and houses must achieve greater than or equal to 45dB sound insulation for airborne tests and less than or equal to 62dB for impact tests. Converted properties have slightly easier targets.
  • Testing typically takes place very close to completion but before carpets or other flooring is laid.

We issue UKAS test certificates for each test.

Why use ALT?

  • Helpful – we work with you to achieve the best result, identifying potential issues and repeating the testing once these have been addressed. We are on hand to answer any questions before, during and after the testing
  • Knowledgeable – we have been air testing since 2002 and all our test engineers have a vast amount of experience
  • Flexible – we try to fit in with the dates and times you need the test, we try to work around other trades to minimise disruption on site
  • Responsive – we issue quotes and certificates within 1 working day, our lead-times are typically around a week but we will try and fit you in sooner if required
  • Great value – our prices are very competitive but we can also undertake air and sound testing on the same visit to save you more money. If you do manage to find the testing cheaper, we will beat any quote.
