Acoustic Barrier Sheet
Soundlay Plus Sru Insulation
At Advanced Seals and Gaskets Ltd, we take pride in offering a wide range of sponge and rubber sheeting products, including a specialist range of acoustic solutions. One of our key products is the Class ‘O acoustic polyurethane with barrier sheets – high-quality composite sheets designed to provide superior sound insulation.
These sheets are created by splitting Class ‘O acoustic polyurethane blocks and laminating them with mass-loaded vinyl (MLV) barrier material. Due to its density, the vinyl is generally produced in sheet form and then combined with the foam to deliver excellent soundproofing properties.
Because all splitting and laminating are carried out in-house, we can supply thicknesses of up to 100mm and offer various composite combinations to meet specific requirements. Sheets can also be supplied plain, self-adhesive backed, or with a foil finish, depending on the application.
What is Class ‘O’ Acoustic Polyurethane with Barrier?
Polyurethane is a highly versatile material, and Class ‘O’ acoustic foam is a specialist variety designed for noise reduction and safety. This open-cell, lightweight material is flame-retardant, non-dusting, and resistant to mildew and fungal growth, providing excellent thermal and acoustic insulation.
When combined with a mass-loaded vinyl barrier layer, it forms a composite sheet that not only absorbs sound but also blocks transmission between spaces. In many cases, the vinyl is sandwiched between two layers of acoustic foam to create a highly effective noise-reduction panel.
We supply acoustic polyurethane with barrier sheets in three standard weights:
- 5kg (approx. 2.5 – 3mm thick)
- 7.5kg (approx. 3 – 4mm thick)
- 10kg (approx. 4 – 5mm thick)
The greater the weight, the stronger the soundproofing capability. MLV itself is made from a blend of calcium silicate or barium sulfate with vinyl, which delivers density for noise reduction while remaining 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 is specifically engineered for applications requiring a high level of soundproofing. By combining a noise barrier with a sound-absorbing material, these sheets effectively reduce sound transmission and vibration.
Because the foam is Class ‘O’ rated, it is flame-retardant and safe for use in industries such as:
- Construction (walls, ceilings, plant rooms, flooring)
- HVAC (duct lining, enclosures)
- Automotive (engine bays, vehicle soundproofing)
- Marine (engine rooms, vessel insulation)
They are ideal for blocking everyday noise from machinery, construction, traffic, and even aircraft, making them suitable for both industrial and commercial applications.
The Advantages of Using Class ‘O’ Acoustic Polyurethane with Barrier
Choosing these acoustic sheets offers a wide range of benefits, including:
- Effective soundproofing and vibration dampening
- Flame-retardant properties for added safety
- Use as sound and vibration absorption panels.
- Suitable for creating soundproof enclosures for noisy machinery
- Flexible installation compared to rigid soundproof boards
- Can be used in flooring, ceilings, walls, and more
Unlike standard acoustic boards, the addition of MLV makes these sheets flexible and easy to cut or shape around corners, pipes, and irregular spaces – ensuring both performance and practicality.
Benefits of Using Class ‘O’ Acoustic Polyurethane with Barrier
- Can be applied to floors, walls, and ceilings
- Reduces unwanted vibration and noise transmission
- Fire-resistant and. Class ‘O’ certified.
- Available as standalone MLV sheets or laminated composites
- Sheets can be cut into pads, strips, gaskets, or panels.
- Supplied in various thicknesses and weights
- Resistant to mildew and fungal growth
