What is Acoustiblok Isolation Membrane?
Acoustiblok Soundproofing Insulation is a unique acoustic soundproofing material used to treat and prevent noise problems. It is held as the reference sound insulation material offering the highest levels of soundproofing millimetre for millimetre.
Where is Acoustiblok Isolation Membrane commonly used?
Our materials have been used in pretty much every sector you would imagine including film sets, film and music studios / production, BBC, audio visual with commercial and private cinemas, theatres, oil rigs, board rooms, conversions of residential projects, marine with all types of vessels, military applications, hotels, medical facilities, transport, automotive, education, libraries…… you name it….
Do I need to use Acoustiblok materials in my project?
Acoustiblok is an advanced insulation product which has been recognised for years as being unique and bringing something rather special to offer the highest levels of acoustic insulation, mm for mm. For example when building a stud wall – the studs are still required for structure, the cavity insulation is sensible for absorption of sound and the finishing board is obviously needed whilst bringing density and mass for deflection of sound. This standard 100mm detail achieves approximately 36dB. But when simply adding our Acoustiblok 3mm to this same buildup – 53dB. A huge difference in just 3mm. Do you need our technology? Usually the answer is yes!
How thick is the Acoustiblok Isolation Membrane?
3mm and 6mm versions are available.
What thickness Acoustiblok Isolation Membrane is typically used in wall applications?
Invariably 3mm materials is used for walls and ceilings.
What thickness Acoustiblok Isolation Membrane is typically used for floor applications?
Invariably 6mm materials is used within floor buildups.
Do you manufacture perimeters around a property?
Yes. This material is called AcoustiFence Perimeter Barrier Membrane and is a reinforced version of the 3mm material. This material has been designed specifically for attaching to existing structural fencing barriers, be they timber or metal.
Are there external acoustic panels for reducing industrial acoustic noise from things like generators, plant, refrigeration systems, air handling?
Yes. Acoustiblok All Weather Acoustic Panels are manufactured using a perforated facia, an acoustic absorptive core and Acoustiblok 3mm Isolation Membrane all housed in a welded stainless steel frame.
Where do I buy the materials?
All materials are sold and distributed directly from the UK and European Head Office based in Kent, England and materials are held in stock in our extensive warehousing near Ashford, Kent.
Do you sell to residential and private individuals ?
Yes. Our materials are typically specified by architects, designers or consultants that are looking for the highest levels of acoustic mitigation within a project but if you know what you need we can sell to the end user or contractor alike. All materials are sold and distributed directly from the UK and European Head Office based in Kent, England and materials are held in stock in our extensive warehousing near Ashford, Kent.
Do I need any accessories as well as the materials?
A range of accessories are available may be purchased where required. Acoustic Silicone Sealant and AcoustiGrip Jointing Tape for overlaps, joins and perimeters, AcoustiPutty Pads for things like back boxes / services.
How do I contact Acoustiblok?
Please give the office a call on +44 1622 840289 or you can contact the offices by email at [email protected]
How does Acoustiblok work?
By way of converting acoustic energy into a less problematic heat energy via a process of thermal conversion and deflection.
What does thermal conversion mean?
When acoustic energy / sound waves contact the Acoustiblok Isolation Membrane it causes the molecules to move creating friction which in turn creates trace element heat which is dissipated sideways through the material.
Can Acoustiblok Isolation Membrane be fixed directly onto a stud wall assembly?
Yes, materials are installed by way of mechanically fixing onto a stud framing system.
Can Acoustiblok Isolation Membrane be fixed into a ceiling assembly by fixing directly into the timber joists?
Yes, materials are installed by way of mechanically fixings, screws or staples with collars / plastic washers to spread the load across the head of the fixing. Please see the video fora typical ceilings installation on the website within Installation Guides.
Is Acoustiblok Isolation Membrane fixed directly to the wall?
Materials are installed by way of mechanically fixing onto a framing system of some type which can be of varying thickness and materials. Similar to a thin batten or stud work wall.
Can the Acoustiblok Isolation Membrane be dot and dab fixed to a wall?
No, materials are installed by way of mechanically fixing onto a framing system of some type which can be of varying thickness and materials.
How is a wall using Acoustiblok Isolation Membrane finished ?
A finishing board of your choice can be applied and mechanically fixed through into the stud or framing system. A cross batten commonly known as a resilient channel can also be detailed to be fixed horizontally over the top of Acoustiblok onto which the board can then be fixed.
How about fixing things through the materials?
See Acoustiblok Installation Guides / Siteworks.
How is the Acoustiblok Isolation Membrane cut?
Usually and typically with a box knife using a straight edge.
Can I get a sample?
Yes. On the website there are hyperlinks on specific pages to ‘Sample pack request forms’ that can be filled in and samples sent.
In the interests of reducing our carbon footprint, saving the planet and reducing paper output, we urge everyone to take time to look through the website at our full range of technical specification data sheets, COSSH details and varying installation methodologies for all the Acoustiblok range of materials.
How long has Acoustiblok as a company been trading?
Acoustiblok has been supplying material across the world for over 25 years and Acoustiblok UK Ltd supplying UK / Europe / Africa / Middle East has been incorporated as a limited company since 2003.
Are these products officially recognised for applications within construction?
Yes the materials are recognised and UL approved for use in varying floor and wall applications.
Walls and facings – U300, U400 and V400
Floors and ceilings – L500
UL Classification
UL classifications indicate the product is safe and has been tested and evaluated against specific properties and hazards. Once a manufacturer has passed all tests within a given standard, they will be given the UL mark.
Does it need a specialist approved installer to instal the systems?
Not necessarily as with a certain level of competency our membranes can be successfully installed. If assistance is required we would always recommend a call is made into the offices where we can offer verbal assistance.
Can Acoustiblok be installed directly onto a concrete slab?
Yes but invariably in conjunction with one of our Acoustiblok AcoustiMat Acoustic Underlays which would be installed first followed by Acoustiblok Isolation Membrane.
What is the compressive strength of Acoustiblok?
Acoustiblok is an inert material and therefore can be installed underneath most flooring systems including tiles, engineered flooring, carpet underlay and carpet.
What is the weight of Acoustiblok Isolation Membrane?
Acoustiblok 3mm weights 4.88kg/m²
Acoustiblok 6mm weights 9.76kg/m²
STC (Sound Transmission Class) Values
The capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power.
DnTw – Weighted Standardised Field Level Difference
DnTw is used in reference to on site sound insulation and it describes the in-situ or onsite airborne sound insulating performance of a part of a completed building. The higher the DnTw, the better the acoustic performance.
LnTw – Weighted Standardised Field Impact Sound Pressure Level
LnTw is the weighted, standardised impact sound pressure level of a floor/ceiling assembly. The lower the LnTw, the better the acoustic performance.
IIC – Impact Insulation Class
Impact Insulation Class (IIC) is an acoustic performance rating used to qualify the levels of impact sound and isolation of vibration to reduce flanking transmissions through a floor / ceiling assembly. Acoustic materials with a high IIC rating help to reduce impact sound transmissions to lower levels. The lowest IIC rated floor / ceiling assemblies may be around 25 however this would be recognised as being acoustically very weak. Mid 50’s is recognised as being much better and acceptable with the highest rating being up to around 85.
Rw – Weighted Sound Reduction Index
It is a rating used to specify the performance of a particular structure, material or product and therefore the difference between the levels of noise one side and the other of an object tested in a laboratory situation.
Rw + Ctr – Weighted Sound Reduction Index Adjusted for Control
DnTw It is the difference between the levels of noise either side of an object tested in a laboratory situation and adjusted accordingly to include how well the strategy or material stops lower frequency.
