Introducing Room Integrity Testing

Introducing Room Integrity Testing

Introducing Room Integrity Testing from APT Sound Testing Services
A Room Integrity test is conducted to estimate the time it takes for fire suppressant agents to reach a specified level in a room without activating the suppression system, typically around 10 minutes for popular gases.

Following the sealing of the room, a series of tests are performed, involving the attachment of a blower fan unit to pressurize and depressurize the enclosure through the test doorway. Subsequently, measurements of pressure and airflow are taken to determine the leakage characteristics of the enclosures. The anticipated retention time is then calculated based on data related to the extinguishing system and the identified leakage characteristics.

APT Sound Testing

Safeguarded Against Potential Fire & Water Damages
Are your valuable systems and assets safeguarded against potential fire and water damage?

For most types of extinguishing systems, a minimum retention time of ten minutes is mandated for the suppressant agents to be contained within the enclosure. According to NFPA 2001, the Standard on Clean Agent Fire Extinguishing Systems, a minimum concentration of 85% of the adjusted minimum design concentration must be maintained at the highest combustibles level for at least 10 minutes. This duration is typically sufficient to prevent re-ignition in most deeply seated fires, allowing ample time for emergency services to intervene and prevent the fire from spreading.

For additional details on our integrity testing services, please reach out to one of our technical sales team members now. We offer room integrity testing for various fire suppression system types and manufacturers throughout England and Wales, whether as part of a system installation or an annual inspection.

A Crucial Component of a Fire Suppression System

Room integrity testing is acknowledged as a crucial component of any fire suppression system. It is imperative that any suppression system agent discharged into a high-risk area can endure for a minimum of 10 minutes from the initial activation of the fire alarm or alert.

For gaseous fire suppression systems safeguarding enclosures like data/server rooms, compliance with room integrity testing is mandated during commissioning, following the stipulations outlined in British Standards BS EN15004 and NFPA 2001. Additionally, annual integrity testing is obligatory as per the BFPSA, and major commercial entities such as banks and data companies are obligated to conduct these tests regularly.

Room Integrity Testing to ISO 15004

According to the ISO standard BS EN15004, it is compulsory to conduct annual integrity testing on enclosures protected by a gaseous fire suppression system. The standard also specifies that if any modifications are made to the building envelope within the annual period, additional testing is necessary as the existing certification becomes invalid. It is important to note that the absence of valid enclosure certification could jeopardize buildings insurance coverage in the event of a fire.

At APT Sound Testing, we have conducted numerous room integrity tests on diverse room types, ranging from large data centers and power station turbine enclosures to small office server rooms. We possess in-depth knowledge of the principles behind extended discharge and hypoxic tests, and our expertise extends to localized smoke testing, which identifies air leakage paths within the room envelope. This enables clients to undertake targeted sealing efforts, enhancing retention times and achieving a pass in room integrity tests.

We offer room integrity testing for various types and brands of fire suppression systems across England and Wales, whether as part of a system installation or an annual inspection. Our engineers utilize cutting-edge testing technology to thoroughly assess potential areas of air leakage, providing advice and recommendations on sealing. Detailed retention and remedial sealing reports are also included.

Part E Sound Insulation Testing

Since July 2003, the mandatory requirement for pre-completion sound testing under Part E of Building Regulations applies to all newly constructed properties and conversions completed after that date. This testing entails examining 10% of each party wall or floor construction type in these structures. The objective of sound testing is to ensure that residential developments can demonstrate satisfactory levels of noise attenuation performance.

To comply with Building Regulations Part E, two distinct types of sound testing must be conducted: airborne noise testing, which assesses sound transmitted through the air (e.g., televisions and conversations), and impact noise testing, which evaluates noise resulting from impacts on the floor surface (e.g., footsteps). These measures are crucial for verifying the effectiveness of sound insulation in rooms separated by party walls or floors.

By undertaking the two types of sound testing ensures the dwelling provides a reasonable resistance to the passage of sound.

Air Tightness Testing

Attaining Satisfactory Air Tightness Testing Levels
The legal mandate for air testing to attain satisfactory air tightness levels was established in 2006 in England and Wales, under Building Regulations Part L. This requirement has grown in significance as it contributes to creating environmentally-friendly buildings by minimizing carbon emissions through the prevention of energy wastage caused by air leakage. Building Regulation Part L defines ‘air leakage’ as the uncontrolled flow of air through gaps and cracks in a building’s structure, commonly recognized by the public as draughts.

Energy loss through a building’s fabric is referred to as the building emission rate. New projects must meet specific air testing and emission rate requirements. The typical target for a standard dwelling is 5.0m3/hr/m2, while commercial buildings often aim for a lower target of around 3.0m3/hr/m2.

Air infiltration and exfiltration are interconnected processes within a building. Infiltration during summer introduces humid outdoor air, while winter exfiltration may lead to moist indoor air causing condensation, mould, or rot, posing potential damage to the property.

We provide air tightness consultancy and design reviews to support our clients from the project’s design phase to pre-completion air testing for building control signoff. For added flexibility, we offer ‘out of hours testing’ on Saturdays or Sundays to minimize the impact on regular working hours.

Our combined air and sound testing packages offer significant cost savings. Our multi-skilled engineers, accredited by UKAS for both Air and Sound Testing, facilitate a streamlined ‘3 step’ precompletion package, eliminating the need for multiple companies. On-site coordination is improved with both tests conducted on the same day in a planned and methodical manner. Out-of-hours testing is also available upon request to minimize disruptions during standard working hours.

By working with our customers throughout their design and construction stages, we can provide advice and guidance on the most feasible ways to avoid air leakage and attain compliance for the air tightness test. Please download our air tightness checklist to help you prepare for your test.

Preparing your Building Fabric for a Heat Pump Installation

Preparing your Building Fabric for a Heat Pump Installation

Preparing your building fabric for a Heat Pump installation

An air source heat pump is a device that transfers heat from the outside air to the inside of a house, using a refrigerant cycle. Air source heat pumps can provide heating and hot water for a home, using renewable energy and reducing carbon emissions; however, for the heat pump to work properly the building fabric needs to be performing correctly.

That’s where we can help, we can undertake a complete building fabric heat pump survey, to check it will be good enough for the heat pump to work at its optimal efficiency.

Thermal Imaging & Air Leakage Surveys to Building Fabrics

For an air source heat pump to work best, the house needs to be well insulated and airtight. This means that the heat loss through the walls, roof, and floors is minimised, and the heat pump can operate at lower temperatures and higher efficiency. Good Airtightness also prevents draughts and cold spots, which can make the house feel uncomfortable and increase the heating demand.

Therefore, a house should be airtight for air source heat pumps to work properly because it will reduce the heat loss, improve the comfort, and lower the running costs of the system. Airtightness can be achieved by using good quality windows and doors, sealing any gaps or cracks in the building envelope, and installing a mechanical ventilation system with heat recovery to provide fresh air without losing heat.

Heat Pump

To try and help clients provide the optimum building fabric conditions prior to the air source heat pumps installation, we provide a combined thermal imaging and blower door air leakage survey to pinpoint any areas of missing insulation and air leakage paths within the building envelope.

Thermal imaging for checking the building fabric

Thermal imaging is a technique that uses infrared cameras to capture the temperature distribution of a surface or an object. Thermal imaging can help when checking your building fabric is properly prepared to install an air source heat pump, because it can:

  1. Identify the areas of heat loss and air leakage in the building envelope, which can reduce the efficiency and performance of the heat pump.
  2. Assess the continuity and quality of the insulation in the walls, roof, and floors, which can affect the heat demand and comfort of the building.
  3. Detect any defects or damages in the building fabric, such as cracks, dampness, or mould, which can compromise the structural integrity and durability of the building.

Thermal imaging can provide valuable information for improving the energy performance and airtightness of the building, which are essential for installing an air source heat pump. However, thermal imaging should be carried out by a qualified professional, who can interpret the results and provide appropriate recommendations. We can provide the thermal imaging using Level 3 Thermographers along with resolution (and sensitivity) Thermal Imaging cameras.

Heat Pump

Air Tightness Testing for checking the building envelope

Air tightness testing and air leakage surveys are methods to measure and locate the amount of air that escapes or enters a building through gaps or cracks in the building fabric. These methods can help to the building fabric before the installation of the air source heat pump, because they can:

  1. Identify the areas of air leakage in the building envelope, which can reduce the air tightness performance of the building envelope, which will have a negative effect on the efficiency and performance of the heat pump.
  2. Assess the continuity and quality of the air leakage line within the building fabric, checking items such as windows, doors, walls/floor/roof junctions which can affect the ongoing heat demand and comfort of the building, especially in the colder months.
  3. Detect any defects or damages in the building fabric, such as unsealed areas around service penetrations which can cause dampness, or mould, which can compromise the structural integrity and durability of the building.

By improving the air tightness of the building fabric, the heat pump can operate at lower temperatures and higher efficiency, resulting in lower energy bills and carbon emissions. However, Air Tightness Testing should be carried out by a qualified professional, who can interpret the results and provide appropriate recommendations. As a UKAS and ATTMA accredited company, we can provide the air tightness testing to strict ISO standards using the latest high power door blower fans and smoke leakage equipment.

What are the Benefits of Combined Blower Door Thermal Imaging Survey?

The main benefits of using this method are:

  • It provides a visual representation of the air leakage in a building, which can help to identify and locate the sources of heat loss, moisture problems, draughts, noise transmission and poor indoor air quality.
  • It provides an air tightness test result, which can be compared against the heat pump manufacturers requirements.
  • It allows for a more accurate diagnosis of the building envelope performance and helps to target remedial works more effectively and efficiently.
  • It can help to achieve higher standards of energy efficiency, comfort, and health in buildings, as well as complying with regulatory requirements.
Heat Pump

The savings of an airtight dwelling with ASHP

The energy savings from an air-tight house with an air source heat pump will depend on several factors, such as the quality of the insulation, the size and age of the house, the climate and the fuel type being replaced – here is some general estimates on the data from the Energy Saving Trust.

According to the Energy Saving Trust, installing a standard air source heat pump in an average three-bedroom semi-detached home in the UK (with radiator upgrades as required) can save up to £860 per year and 1,440 kg of CO2 if you are replacing an old gas boiler, or up to £1,460 per year and 2,320 kg of CO2 if you are replacing an old oil boiler. These figures are based on fuel prices as of Oct 2023.

However, the above approx. savings may vary depending on the efficiency and ongoing running cost of the heat pump, which will depend on the outside temperature, the heat demand of the house, and the electricity tariff. The Guardian reports that in a poorly insulated home, it may cost as much as 40% more to run a heat pump than a traditional boiler, because of the higher cost of electricity compared to gas. Therefore, it is important to improve the insulation and air tightness of the house before installing a heat pump, to reduce the heat loss and increase the savings.

Heat Pump

How to make your building more airtight to reduce heat loss.

There are many areas that can be improved in existing building fabric’s,  prior to the installation of an air source heat pump system. Here is a list of the main air leakage paths within existing properties.

Improve external windows.

For external windows that open, purchase draught-proofing strips to stick around the window frame to fill the gap between the window and the frame. There are usually two types:

  • Self-adhesive foam strips – these are cheap and easy to install but may not last long.
  • Metal or plastic strips with brushes or wipers attached, which are long-lasting, but cost a little more and are usually the better option.

Make sure the weather strip is the right size to fill the gap in your window. If the strip is too big, it will get crushed, and you may not be able to close the window. If it’s too small, there will still be a gap and it will not be airtight.

For sliding sash windows it’s more awkward, foam strips do not work well. It’s best to fit brush strips or consult a professional. For windows that don’t open, use a silicone sealant. If you’re thinking of replacing your windows, consider installing energy efficient windows.

Heat Pump

External Doors

Draught-proofing external doors can stop a lot of heat from escaping and will make your building more airtight and the upgrades shouldn’t cost you much. There are four main areas to consider when draught proofing your doors:

  • Gaps around the perimeter of the door – fit foam, brush, or wiper strips like those used for windows. You will need to measure up the gap and size the weather seal accordingly.
  • Gap at the bottom of the door – use a brush, rubber, or hinged flap draught excluder.
  • Keyhole – buy a cover that drops a metal disc over the keyhole, these can be found at most hardware stores or online.
  • Letterbox – use a letterbox flap; however, remember to measure your letterbox before you buy to ensure the sizing is correct.

If you have a room, you don’t normally heat, such as your conservatory, spare room or kitchen. Keep those doors closed to stop the cold air from moving into the rest of the house. If there is a gap at the bottom of the door, block it with a draught excluder as detailed above.

It’s worth noting that internal doors between heated rooms don’t need draught-proofing, as you don’t lose energy when warm air circulates between habitable spaces.

Heat Pump


If you don’t use your fireplace, your chimney is probably a main source of unnecessary draughts and air leakage. There are two main ways to draught-proof a chimney:

  • Fit a purpose made cap over the chimney pot – this should be done by a professional.
  • Buy a chimney draught excluder – these helps stop draughts and heat loss through the chimney and are usually fitted inside the bottom of the chimney flue.

Please note remember to remove the temporary draught-proofing if you decide to light a fire.

Heat Pump

Skirting boards and Floorboards

You can seal cracks in floors by squirting filler into the gaps. Floorboards and skirting boards often contract at wall/floor junctions causing air leakage paths. Use a sealing material that can tolerate movement – these are usually silicone-based. Look for the following products:

  • mastic-type products
  • flexible fillers
  • decorator’s caulk

Fillers come in different colours, and for indoor and outdoor use. They block gaps permanently so be careful when you apply them – wipe off any excess with a damp cloth before it dries. Fillers may break down over time but can easily be reapplied.

Check whether you also need to insulate between the skirting board and the floor. Find out more in our guide to floor insulation.

Heat Pump

Loft hatches

Hot air rises and gets lost in the cold space in your loft or attic, cold air can also drift down in your warm space via draughts, so it’s worth blocking off gaps around your loft hatch. Use strip insulation, as you would on a door.

Loft Hatch Heat Pump

Pipework and cable penetrations

You can fill small gaps around pipework with silicone fillers, similar to the fillers used for skirting boards and floorboards. Fill larger gaps with expanding polyurethane foam. This is sprayed into the gap, expands as it dries, and sets hard. We have more information about insulating tanks, pipe work and radiators.

Heat Pump

Old extractor fans

Old fan outlet penetrations may need to be filled with bricks or concrete blocks and sealed from both the inside and outside as this can be a major cause of air leakage.

Cracks in walls

You can fill in cracks using cements or hard-setting fillers. These will work around electrical fittings on walls and ceilings and at ceiling-to-wall joists. If there is a large crack in your wall, you may need to check if there’s an underlying problem. Consider consulting a surveyor or builder to see what caused the crack in the first place.

An Introduction & Explanation of BREEAM

An Introduction & Explanation of BREEAM

An Introduction & Explanation of BREEAM
BREEAM (Building Research Establishment Environmental Assessment Method), first published by the Building Research Establishment (BRE) in 1990, is the world’s longest established method of assessing, rating, and certifying the sustainability of buildings. More than 550,000 buildings have been ‘BREEAM-certified’ and over two million are registered for certification in more than 50 countries worldwide. BREEAM also has a tool which focuses on neighbourhood development.


The BREEAM Assessment
BREEAM is an assessment undertaken by independent licensed assessors such as APT Sound Testing using scientifically-based sustainability metrics and indices which cover a range of environmental issues. Its categories evaluate energy and water use, health and wellbeing, pollution, transport, materials, waste, ecology and management processes. Buildings are rated and certified on a scale of ‘Pass’, ‘Good’, ‘Very Good’, ‘Excellent’ and ‘Outstanding’.

It works to raise awareness amongst owners, occupiers and designers of the benefits of taking a sustainable approach, providing a framework to help them to successfully adopt sustainable solutions in a cost-effective manner, and provides market recognition of their achievements. It aims to reduce the negative effects of construction and development on the environment.

BREEAM has expanded from its original focus on individual new buildings at the construction stage to encompass the whole life cycle of buildings from planning to in-use and refurbishment. Its regular revisions and updates are driven by the ongoing need to improve sustainability, respond to feedback from industry and support the UK’s sustainability strategies and commitments.

Highly flexible, the BREEAM standard can be applied to virtually any building and location, with versions for new buildings, existing buildings, refurbishment projects and large developments:

BREEAM New Construction is the BREEAM standard against which the sustainability of new, non-residential buildings in the UK is assessed. Developers and their project teams use the scheme at key stages in the design and procurement process to measure, evaluate, improve and reflect the performance of their buildings.

BREEAM International New Construction is the BREEAM standard for assessing the sustainability of new residential and non-residential buildings in countries around the world, except for the UK and other countries with a national BREEAM scheme (see below). This scheme makes use of assessment criteria that take account of the circumstances, priorities, codes and standards of the country or region in which the development is located.

BREEAM In-Use is a scheme to help building managers reduce the running costs and improve the environmental performance of existing buildings. It has two parts: building asset and building management. Both parts are relevant to all non-domestic, commercial, industrial, retail and institutional buildings. BREEAM In-Use is widely used by members of the International Sustainability Alliance (ISA), which provides a platform for certification against the scheme. The newest version v6, available from 2020 includes also Residential programs.

BREEAM Refurbishment provides a design and assessment method for sustainable housing refurbishment projects, helping to cost-effectively improve the sustainability and environmental performance of existing dwellings in a robust way. A scheme for non-housing refurbishment projects is being developed and is targeted for launch in early 2014. The launch date will be announced once the piloting and independent peer review processes has been completed.

BREEAM Communities focuses on the masterplanning of whole communities. It is aimed at helping construction industry professionals to design places that people want to live and work in, are good for the environment and are economically successful.

BREEAM includes several general sustainability categories for the assessment:

>>> Management
>>> Energy
>>> Health and wellbeing
>>> Transport
>>> Water
>>> Materials
>>> Waste
>>> Land use and ecology
>>> Pollution

Home Quality Mark was launched in 2015 as part of the BREEAM family of schemes. It rates new homes on their overall quality and sustainability, then provides further indicators on the homes impact upon the occupants ‘Running costs’, ‘Health and wellbeing’ and ‘Environmental footprint’.

Here at APT Sound Testing we have been providing indoor air quality services such as post-construction air quality testing and indoor air monitoring for a number of years. We have assisted many customers in gaining their BREEAM and other compliance credits through our air quality plan and BREEAM air quality testing services.

Air Quality Testing in the Property Industry

Air Quality Testing in the Property Industry

The Importance of Air Quality Testing in the Property Industry
In recent years, the focus on health and well-being has grown significantly, leading to a heightened awareness of the importance of indoor air quality (IAQ). This concern has permeated various sectors, with the property industry standing out as a crucial player in ensuring the well-being of occupants. Indoor air quality testing has emerged as a pivotal tool for property owners, developers, and managers to assess and enhance the air quality within buildings.

Air Quality Testing

This post delves into the significance of indoor air quality testing in the property industry, exploring its impact on human health, property value, and overall occupant satisfaction.

Understanding Indoor Air Quality:

Indoor air quality refers to the condition of the air within buildings and structures, especially as it relates to the health and comfort of the occupants. It encompasses a range of factors such as the presence of pollutants, ventilation, temperature, and humidity levels. Poor indoor air quality can have detrimental effects on health, leading to respiratory issues, allergies, and other health problems.

The Property Industry’s Role:

The property industry plays a vital role in shaping the built environment, and as such, it carries a significant responsibility for the well-being of its occupants. Indoor air quality is a key aspect of this responsibility, as individuals spend a considerable amount of time indoors, whether at home, in offices, or other commercial spaces. Recognizing the impact of indoor air quality on the health and productivity of occupants, the property industry has increasingly turned its attention to comprehensive IAQ testing.

Health Impacts:

The link between indoor air quality and health is well-established. Poor air quality can contribute to respiratory problems, exacerbate existing conditions such as asthma, and even lead to long-term health issues. By conducting regular indoor air quality testing, property owners can identify and address potential sources of pollution, ensuring a healthier environment for occupants.

Occupant Satisfaction and Productivity:

The quality of indoor air has a direct correlation with occupant satisfaction and productivity. Employees, residents, and visitors are more likely to feel comfortable and perform better in spaces with good air quality. The property industry, recognizing this, has started to prioritize IAQ testing as a means to create environments that promote well-being, thereby increasing tenant satisfaction and overall property value.

Property Value and Market Competitiveness:

Indoor air quality has become a key consideration for individuals and businesses looking for properties. A building with a strong focus on IAQ is more likely to attract tenants and buyers. As sustainability and wellness trends gain momentum, properties with good indoor air quality stand out in the market, potentially commanding higher values. IAQ testing, therefore, becomes an essential component of a property’s overall competitiveness in the real estate market.

Regulatory Compliance:

Governments and regulatory bodies are increasingly recognizing the importance of indoor air quality and implementing standards to ensure the well-being of building occupants. Property owners and managers must stay informed about these regulations and comply with IAQ standards to avoid legal issues and potential liabilities. Indoor air quality testing serves as a proactive measure to ensure compliance with existing and emerging regulations, safeguarding both occupants and property owners.

Common Indoor Air Pollutants:

To effectively address indoor air quality, property professionals must understand and identify common indoor air pollutants. These may include:

(1) Volatile Organic Compounds (VOCs): Released from paints, cleaning products, and furnishings.

(2) Mold and Mildew: Thrives in damp and poorly ventilated spaces, leading to respiratory issues.

(3) Particulate Matter (PM): Tiny particles from combustion, construction, or other sources that can be inhaled into the lungs.

(4) Carbon Monoxide (CO): Produced by incomplete combustion of fossil fuels, posing serious health risks.

(5) Radon: A naturally occurring radioactive gas that can seep into buildings, leading to lung cancer.

Importance of Professional IAQ Testing:

While property owners can take some measures to improve indoor air quality, professional IAQ testing is essential for a comprehensive assessment. Certified professionals use specialized equipment to measure pollutant levels, identify sources, and provide recommendations for improvement. This approach ensures accurate and reliable results, guiding property owners in making informed decisions to enhance IAQ effectively.

The IAQ Testing Process:

Professional indoor air quality testing typically involves several key steps:

(1) Initial Assessment: Evaluating the property’s design, occupancy, and potential sources of pollutants.

(2) Monitoring: Using specialized equipment to measure levels of pollutants such as VOCs, PM, CO, and humidity.

(3) Sample Collection: Collecting air or surface samples for laboratory analysis to identify specific pollutants.

(4) Analysis and Reporting: Interpreting the results and providing a detailed report with recommendations for improvement.

(5) Implementation of Solutions: Taking corrective measures to address identified issues and improve indoor air quality.

Indoor Air Quality Testing ~ a Crucial Component
Indoor air quality testing has become a crucial component of the property industry’s commitment to providing healthy and sustainable built environments. As the awareness of the impact of indoor air quality on human health and well-being continues to grow, property professionals must prioritize IAQ testing to meet regulatory requirements, enhance property value, and ensure occupant satisfaction.

In doing so, the property industry can contribute to the creation of healthier and more livable spaces, aligning with the evolving expectations of occupants and stakeholders.

Acoustic Design & Testing

We have undertaken hundreds of acoustic design and testing packages on many different types of projects, from the initial scheme stage to completion. We offer a no nonsense professional proactive service that ensures your company receives professional advice every step of the way, with a continual consideration of cost.

We are also a UKAS accredited testing laboratory sound insulation testing service which means we can test and issue certification on completion of any works carried out and you can be safe in the knowledge that the results will be accepted by the tasked building control company.

Our roadmap to pass precompletion sound testing

We can help develop the acoustic design of the project from the initial design scheme stage through to the precompletion sound testing. In particular we review the acoustic details to consider the mass, isolation, and absorption elements of the construction.

To try and help our clients achieve compliance with Approved Document E, we offer the following 4 step acoustic design advice package:

  1. Site Survey Visits – to let us view the existing site construction. This allows us to check for potential problematic construction such as inclusion of lightweight blocks in the existing construction. It also lets us check that the installation teams are installing the acoustic materials as per manufacturer’s guidelines.
  2. Sample Sound Testing – of the existing construction. This offers an accurate overview of the acoustic performance of the existing partitions which enables us to offer a targeted acoustic design using the sound insulation performance of the existing construction.
  3. Acoustic Design Review – a full design review of the proposed developments party walls and floors. Site Survey Visits – to let us view the existing site construction. This allows us to check for potential problematic construction such as inclusion of lightweight blocks in the existing construction. It also lets us check that the installation teams are installing the acoustic materials as per manufacturer’s guidelines.
  4. Final pre-completion Sound Testing to satisfy Approved Document E and attain building control signoff.

Acoustic advice for passing the Party Floors sound testing

To reduce airborne and impact sound transmission this usually means adding density and isolation to the floor construction. This can be as simple as adding a drop ceiling consisting of 125mm timber frame. The top of the frame must be a minimum of 25mm below the existing ceiling finish – such as lathe and plaster.

Then, to the inside of the timber frame add 100mm of Acoustic Wool and two layers of sound-board tacked to the bottom of the timber frame – all boards to be lapped. This should improve your sound test results by approx. 15dB depending on the existing site conditions and quality of the installation.
