postheadericon Room Integrity Testing in London

There are literally tens of thousands of protected enclosures throughout London and the South East. With many of the banking and commercial institutions based in the capital the requirement to provide a safe environment of for critical equipment is greater than ever.


It is now a requirement of the BFPSA that all protected enclosures such as server rooms and/or data centres have valid enclosure certification – it is also a requirement of all major commercial institutions. The benefits of ensuring room integrity are widely recognised by insurers and regulatory authorities, who frequently require room integrity testing & sound testing in London to prevent critical system failure on valuable assets such as server rooms and data centres.  It is also worth noting that you may negate your buildings insurance if you don’t have the valid certification.


Enclosures protected by gaseous fire suppression system -such as server rooms should be tested for air-tightness upon commissioning of the system and annually thereafter. This is critical to ensure that the system will work effectively when activated; too much air-leakage will result in the concentration of the fire suppressant agent falling too quickly resulting in rapid fire spread as shown in the image.

For most extinguishing system types, a retention time of ten minutes is the minimum period the suppressant agents is required to be retained for within the enclosure. NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems, requires that a minimum concentration of 85% of the adjusted minimum design concentration be held at the highest level of combustibles for a minimum period of 10 minutes. This is usually long enough to prevent re-ignition for most deep-seated fires and should provide adequate time for the emergency services to attend and prevent the fire taking hold.


Unfortunately, in the relevant ISO standard BS EN15004if you don’t have valid room integrity certification you may negate your buildings insurance in the event of a fire. In all instances the integrity certification should always be attached to the front of the protected enclosure/s to show it has valid certification and to clearly show the dates of the next test. The certification also has other useful information that should be adhered to at all times. If you don’t have integrity test certification fixed to the front of the enclosure, then the chances are that your enclosure may not have valid certification.


Within the In many cases the stakeholder may not be aware that any modifications have been undertaken to the room’s envelope as this may further reduce the integrity of the enclosure envelope.  That is why it’s always best to plan any works within protected enclosures so that everyone’s aware of the importance of maintaining the integrity of the enclosure envelope and the requirement for a fresh integrity test after any modifications have taken place.


Smoke Testing to Find Air Leakage Paths

APT’s highly trained and experienced Enclosure Testing Engineers will be able to locate the problem areas and identify where air is leaking out of the building by walking around the test enclosure with a localised smoke puffer – as shown in the image below)  checking the most common problem areas first.

By combining our door fan blower equipment and a small smoke puffer we can quickly locate any penetrations in in the enclosure envelope as the smoke is more visible. Smoke leaking from the enclosure can be easily seen and photographed to provide a record of any external leakage paths.
Pressurised smoke tests are ideal for identifying both generic and torturous areas of air leakage. Crucial remedial sealing work should then be undertaken to reduce the leakage from the enclosure. The sealing works may include:


  • Sealing all holes, cracks or penetrations leading into or out of the protected space
  • Pipe chases and cable trays to be sealed around the outside and inside where they penetrate the perimeter boundaries of the enclosure
  • Walls to be caulked around the inside perimeter at both high and low level
  • Sealing of porous block walls
  • Addition of door sweeps or drop seals, weather stripping around jambs
  • Sealing of windows/glazed sections to the area


One of the advantages of the sealing works being conducted whilst a test fan kit is in place, is that it can be seen if the works being conducted are effective via ongoing smoke testing and sealing works. Once the appropriate remedial work has been undertaken the enclosure should be retested to confirm the acceptable retention time as been achieved – usually 10 minutes.


Air Pressure Testing provides the necessary Room Integrity Testing in London to the required NFPA 2001 or ISO 14520 methodologies. We have undertaken hundreds of enclosure integrity tests around the UK and Europe.

As part of our service, we can also arrange an annual test plan and remind you when the enclosure test/s are required to make sure your buildings insurance is not at risk. If you require room integrity testing  & sound testing in London, please visit the APT Sound Testing website today.

postheadericon Sound Insulation Testing in London

London is a massive city containing over 9 million people density and high rise apartments. With many living in this overcrowded environment it is essential that noise transference between adjoining properties in kept to a minimum for the occupant’s wellbeing. One way of ascertaining that a building is in compliance with Building Regulations Part E for the prevention of noise transference, is to undertake Sound Insulation Testing in London.

We have undertaken thousands of sound insulation tests throughout London and the South East on all types of projects from simple flat conversions to large developments containing hundreds of flats. We also undertake Sound Insulation Testing where a lease holder dispute has arisen, i.e. where the buildings lease stipulates that wooden floors should not be used instead of carpets and as a result of the change of floor finish the noise levels have increased– especially the impact noise. We can also undertake sample sound testing to highlight the existing noise levels so a targeted acoustic design can be undertaken.

Plate A – Tapping Machine for Impact Sound Testing

Currently we are also experiencing a rise in the amount of sound testing required to existing blocks of flats, such as existing council stock. This is hardly surprising as the amounts of noise complaints have more than doubled within the last 10 years due to residents experiencing excess noise between the dividing wall and floor partitions. By utilising our extensive knowledge of different materials and constructionwe canforward a simple, explanative cost effective solution for wall and/or floor upgrade. Where our clients have followed our advice they have achieved a 100% success sound test pass rate, ensuring compliance with Part E of Building Regulations.

The Sound Testing procedure is fairly simple and our engineer will be happy to explain this on site. Essentially, for party walls there is one type of sound insulation test which is airborne sound test and for compartment floors there are two types of sound insulation tests which are airborne and impact sound insulation tests. The airborne sound insulation test is carried out by means of a loudspeaker emitting a steady source of noise on one side of the partition (wall or floor) to be measured. The corresponding sound level is measured on the other side of the partition. Impact sound insulation tests are carried out by means of a tapping machine placed on the floor sample to be measured and the noise measured in the room or space below

All our engineers carry out the sound test measurements in full accordance with the measurement procedures of BS EN ISO 140-4:1998[3] for field measurements with a single figure DnTw and LnTw in accordance with BS EN ISO 717.

Ongoing problems with airborne and structure borne sound are often associated with direct noise flanking transmission through floors and supporting walls and other associated structures. One common cause of noise flanking is often associated with the inclusion of lightweight blocks within the construction of the building envelope and/or blocked cavities. It all cases it is essential to establish if your problem is due to direct transmission, flanking transmission or a combination of both so that the most cost effective remedial treatment can be chosen.

Unwanted noise travelling along flanking paths will make the building structure vibrate which causes the sound to radiate into your room. One simple cost effective solution is to build another wall or ceiling in front of the original, but not connected to it (often called an independent wall or ceiling) so it provides isolation between materials.

One way to reduce the chance of flanking transmission is through careful consideration to the design at the start of the project.  Unfortunately, by simply specifying high performance wall and floor partitions it is no guarantee to adequate sound isolation and successful sound testing.

APTSound Insulation Testing offer both preconstruction and post construction design solutions if a project has failed the sound testing. We also offer onsite inspection services to ensure that the sound insulation elements are being installed as per manufactures guild-lines.
