JCW Acoustic Supplies – A UK Leader In Soundproofing And Sound Absorption
About JCW Acoustic Supplies
JCW Acoustic Supplies provides soundproofing and sound absorption products for domestic, commercial and construction projects throughout the UK.
The business developed from practical experience within acoustic flooring and floor screeding. Working directly on building projects provided an understanding of how acoustic materials need to perform not only in technical specifications, but also during installation on a live construction site.
This experience helped shape the development of a broader range of acoustic systems for floors, walls, ceilings, doors and internal spaces.
Our Origins in Acoustic Flooring
Early work involved installing acoustic decking, resilient battens and flooring products supplied by other manufacturers.
Combining acoustic flooring installation with floor screeding gave contractors and quantity surveyors the opportunity to coordinate related elements of the floor construction through one supplier.
Experience gained from these projects also highlighted the importance of ensuring that individual materials work together as a complete acoustic system.
An acoustic floor may involve more than an underlay or resilient batten. Its performance can depend on the structural floor, cavity treatment, perimeter isolation, deck construction, floor finish and quality of installation.
The Influence of Approved Document E
Changes to the acoustic requirements of the Building Regulations increased the construction industry’s focus on resistance to the passage of sound between homes and different parts of a building.
Approved Document E provides guidance relating to sound insulation in dwelling-houses, flats, rooms for residential purposes and other applicable buildings.
These requirements encouraged architects, developers and contractors to give greater consideration to separating floors, walls and other sound transmission paths during both new-build and conversion projects.
Compliance cannot be achieved simply by selecting a product with a suitable description. The complete construction, junction details, workmanship and treatment of flanking sound paths can all affect the finished acoustic performance.
Developing Our Own Acoustic Products
After gaining experience installing systems from other manufacturers, the business began developing and supplying its own acoustic products.
This allowed practical installation experience to inform decisions about product construction, handling and integration with other building materials.
The product range developed to support projects involving:
- Separating floors in houses, flats and multi-occupancy buildings
- Party walls and internal partitions
- Ceilings beneath residential and commercial spaces
- Doors and other acoustic weak points
- Internal echo and reverberation
- External noise barriers and fencing
- Studios, offices and entertainment spaces
Different products perform different roles. Boards may add mass, resilient components may reduce direct vibration transfer, acoustic insulation may control cavity resonance and sealants may close small air paths.
The most suitable result normally comes from selecting components that work together as a complete system.
Product Development and Acoustic Testing
Product development is an important part of supplying acoustic systems for construction projects.
Where applicable, technical information and acoustic test evidence help architects, contractors and customers understand the intended use and expected performance of a product or system.
Laboratory tests can provide controlled performance data, while on-site testing assesses the completed construction within an actual building.
Site performance may differ from laboratory results because it is influenced by:
- The existing building construction
- Installation workmanship
- Junctions with adjoining surfaces
- Doors, windows and service openings
- Flanking transmission
- Changes made to the specified system
Test results should therefore be read alongside the complete system specification rather than treated as a guarantee for every property.
Floor Soundproofing
Floor soundproofing can be used to reduce impact noise, airborne noise or a combination of both.
Depending on the project, a floor system may include acoustic battens, resilient cradles, underlays, acoustic decks, cavity insulation or floating floor components.
Timber and concrete floors behave differently and should not automatically receive the same treatment. The intended floor finish, available build-up height and required acoustic performance must also be considered.
Perimeter isolation is particularly important. A floating floor that makes rigid contact with surrounding walls can allow vibration to bypass the resilient layer.
Wall Soundproofing
Wall soundproofing may help reduce conversations, television noise, music and other airborne sound passing through a separating wall.
A suitable system may combine acoustic insulation, resilient bars or isolation clips, dense boards and flexible perimeter sealing.
The correct build-up depends on whether the original wall is masonry, blockwork, timber stud, metal stud or another form of construction.
Connected floors, ceilings, chimney breasts, sockets and service routes should also be assessed. Treating the visible wall alone may provide limited improvement if sound can travel around it.
Ceiling Soundproofing
Ceiling soundproofing may be used where voices, televisions, footsteps or other activity can be heard from above.
Systems may include acoustic insulation between joists, resiliently mounted boards or an independent ceiling beneath the original structure.
An independent ceiling can create greater separation, but it will reduce the available room height. Lighting, alarms, ventilation and service openings must also be incorporated carefully.
Where impact noise is involved, treatment to the floor above is normally preferable when access and ownership allow. A ceiling treatment may reduce the direct path while some vibration continues through adjoining walls.
Acoustic Doors and Other Weak Points
A room enclosure can be weakened by a lightweight door or gaps around its frame and threshold.
A soundproof door may be suitable where the doorway has been identified as a significant transmission path.
The performance of an acoustic doorset depends on the door leaf, frame, perimeter seals, threshold, ironmongery and quality of installation.
A specialist door will provide limited value if most of the noise is travelling through an untreated wall, ceiling void, raised floor or ventilation system.
Soundproofing and Sound Absorption
Soundproofing and sound absorption are related acoustic disciplines, but they solve different problems.
Soundproofing helps reduce noise passing from one room, property or area to another. Sound absorption controls echo and reverberation within the same space.
Absorptive wall panels, ceiling treatments, screens and other products can improve speech clarity and make an internal environment less reflective.
They should not be relied upon to block voices, music, traffic or footsteps through walls, floors or ceilings.
Studios, offices, schools and entertainment spaces may require both soundproofing and absorption, but each treatment must be selected for its intended purpose.
Supporting Domestic and Commercial Projects
JCW Acoustic Supplies works with a range of customers and project types, including:
- Homeowners and experienced DIY installers
- Builders and specialist contractors
- Architects and acoustic consultants
- Developers and housing providers
- Offices and commercial organisations
- Schools and public buildings
- Studios and entertainment venues
- Factories and industrial premises
Home soundproofing projects may involve neighbour noise, footsteps between floors, external traffic or sound travelling between rooms.
Office soundproofing may involve meeting-room privacy, noise between adjoining businesses, mechanical services or reverberation in open-plan spaces.
Each project should be considered according to its building construction, noise source and required outcome.
Installation Is Part of Acoustic Performance
Even a suitable acoustic system can underperform if it is installed incorrectly.
Common problems include rigid fixings bridging resilient components, unsealed perimeter joints, compressed insulation and untreated service penetrations.
Some products may be suitable for an experienced DIY installer who follows the relevant guidance carefully. More involved systems may require a competent tradesperson or specialist acoustic installer.
Professional installation may be appropriate for projects involving independent walls, floating floors, suspended ceilings, acoustic doors, ventilation alterations or fire compartmentation.
Growth of JCW Acoustic Supplies
As demand from builders’ merchants, contractors and specialist customers developed, JCW Acoustic Supplies expanded its office and warehouse operations at Waters Meeting Development in Bolton.
The wider product and service range now allows the business to support projects from initial product selection through to installation and acoustic testing where required.
Although the business has grown, the underlying approach remains the same: understand the noise problem, identify the transmission path and recommend a coordinated system rather than relying on one product to solve every situation.
