Acoustic Barrier Sheet
Advanced Seals and Gaskets Ltd take great pride in the vast range of sponge and rubber sheeting materials we offer, including many specialist products, one such product being class ‘O’ acoustic polyurethane with barrier sheets.
These speciality, high-grade composite sheets are manufactured using the class ‘o’ acoustic polyurethane sheets which are split from blocks and then laminated with mass loaded vinyl barrier material which is usually manufactured in sheet form due to the weight of the product.
As our class ‘o’ acoustic foam materials are split and laminated in-house, we are able to offer any thickness up to 100mm and in a range of composite combinations using the acoustic foam and layers of a mass loaded vinyl barrier, which can be supplied plain, self-adhesive backed or with a foil backing.
What is Class ‘O’ Acoustic Polyurethane with Barrier?
There are many types of Polyurethane materials, one of which is Class O acoustic foam, used to manufacture our polyurethane with barrier sheets. This particular variety of material is open cell, lightweight, flame retardant, non-dusting, doesn’t support mildew or fungal growth and has excellent thermal insulation and noise absorption properties. The addition of the mass loaded vinyl barrier layer creates a composite material, which is designed to reduce noise within enclosed areas, whilst being fire resistant.
Generally, the mass loaded vinyl barrier is sandwiched between 2 layers of acoustic foam, however, more than one layer can be added depending upon the level of soundproofing required. The acoustic polyurethane with barrier sheets are available in 3 weights and thicknesses as standard, 5kg (2.5 - 3mm thick), 7.5kg (3 - 4mm thick) and 10kg (4-5mm thick), the heavier the weight, the more soundproofing properties the sheet will offer.
The mass loaded vinyl or MLV is a thick flexible material that has been specifically designed for soundproofing. It is made up using a combination of calcium silicate or barium sulfate which create the sound deadening property, combined with vinyl which makes the material flexible for easier installation.
The primary benefit of acoustic barrier sheets is their ability to reduce the transmission of sound. They act as a barrier to prevent the passage of noise from one space to another, making them effective in minimizing both airborne and impact noise.
Acoustic barrier sheets are often used in walls and ceilings to enhance privacy by preventing the transmission of conversations or other noises between rooms. This is particularly important in residential, office, or commercial settings.
By blocking external noises, acoustic barrier sheets contribute to creating a more comfortable and peaceful indoor environment. This can lead to increased well-being and productivity in workplaces or improved sleep quality in residential settings.
Acoustic barrier sheets can be applied to various surfaces, including drywall, plywood, metal, and other construction materials. This versatility makes them suitable for a wide range of applications in different types of buildings and structures.
Many acoustic barrier sheets are designed to be easy to install. They can be cut to size and applied to existing walls or incorporated into new construction projects. This makes them a practical solution for retrofitting or upgrading spaces.
Acoustic barrier sheets are often thin and lightweight, allowing them to be discreetly integrated into construction elements without significantly altering the overall design or structure of a space.

Why use Class ‘O’ Acoustic Polyurethane with Barrier Sheets?
Class ‘O’ Acoustic Polyurethane with Barrier sheets (MLV) have been designed for use where a high degree of soundproofing is required within enclosed areas. The creation of the composite Polyurethane with barrier sheet combines a noise barrier and sound absorber into a single product, which also helps with sound transmission loss and vibration dampening.
Being a class ‘O’ material, these Polyurethane with barrier sheets are flame retardant, making them safe to use in a range of industries including HVAC, construction and automotive where they are often found used to line walls and ceilings, plant rooms or enclosures for noisy machinery. The addition of the mass loaded vinyl barrier to the acoustic foam enables the composite sheet to be used for blocking out everyday sounds and noise from construction, traffic and even aircraft.
The Advantages of Using Class ‘O’ Acoustic Polyurethane with Barrier
Using Class ‘O; acoustic polyurethane with barrier sheets offer a huge number of benefits and uses. Not only do they help with soundproofing, but they also act as sound and vibration absorption panels, and can help sound transmission loss. These polyurethane with barrier sheets and products can be used to create soundproof enclosures in which noisy machinery and equipment can be housed and also as linings within automotive and HVAC applications.
As the class ‘o’ foam is flame retardant, it is often one of the safest materials to use within building and construction for soundproofing underlay under flooring, combined with plasterboard on walls and ceilings, especially studios or home cinema rooms and even within engine rooms such as on marine vessels.
The addition of the MLV barrier to the foam creates further features and properties to the acoustic Polyurethane with barrier sheets, it allows the polyurethane foam to block more noise compared to using the foam by itself, its allows for noise absorption rather than blocking it out and finally many soundproofing boards or tiles can be quite rigid and therefore difficult to cut and install, whereas the MLV barrier is flexible, therefore easy to curve and wrap around corners and pipes, etc.
Benefits of using Class ‘O’ Acoustic Polyurethane with Barrier
- Can be used as floor, wall or ceiling linings for soundproofing
- Reduce unwanted vibration
- Flame retardant
- Can be supplied as a barrier sheet alone or laminated between acoustic foam
- Sheets can be cut down into smaller parts such as pads, strips or even gaskets
- Available in various thicknesses and weights
- Doesn’t support mildew or fungal growth
Different Types Available
The soundproofing barrier material can be supplied in a range of formats, as the mass loaded vinyl barrier alone, alternatively, it can be supplied laminated to class ‘o’ acoustic foam to create composite sheets.
Mass loaded vinyl barrier is available in 3 weights:
5kg - thickness approx 2.5mm - 3mm (Acoustic performance 26 dB approx)
7.5kg - thickness approx 3mm - 4mm
10kg - thickness approx 4mm - 5mm (Acoustic performance 32 dB approx)
Finishes: Class ‘O’ acoustic Polyurethane foam with Barrier can be supplied plain, with a self-adhesive face to allow for quick and easy installation, or covered with a foil face with the option of a scrim lined foil, which increases the insulation properties of the acoustic barrier sheets even further.
