Acoustic Roll Insulation (APR)

Acoustic roll, also known as sound insulation roll or acoustic insulation blanket, is a type of mineral wool insulation designed to reduce the transmission of airborne noise between rooms or floors in a building, mostly used as internal wall insulation or floor insulation. Most acoustic insulation comes in rolls of mineral wool insulation of varying thicknesses and densities to suit the depth of your wall or floor. Our most popular acoustic roll products are manufactured by Knauf, Isover and Rockwool, and are made from a glass mineral wool.

To install acoustic insulation roll, simply roll it out evenly between the joists or studs in walls, floors, or ceilings, ensuring it fits snugly without any gaps.

Our acoustic insulation is available in a variety of lengths and thicknesses, but the common theme across most brands is their width, as they are specifically sized at 600mm to fit between the studs in most modern stud walls. The most common thicknesses are 25mm, 50mm, 75mm and 100mm. When selecting a thickness, choose the closest size to the depth of your cavity - try to avoid more compression than is necessary. 

The U-value (thermal transmittance) of a building component such as a wall, roof, or window, measures its thermal conductivity or how easily heat can pass through it. The lower the U-value, the better the insulation. To calculate the U-value, you typically need to consider several factors, including the materials used, their thicknesses, and any air gaps. A general formula for calculating the U-value:

U = 1 over R

Where:

U = U Value

R = The total thermal resistance of the building component, including all layers of materials and air gaps.

However, with Acoustic insulation, some manufacturers do not supply a R value, as the primary focus of the product is acoustic performance rather than thermal, and it is therefore not tested against that criteria. Though virtually all acoustic insulation will have some thermal insulating properties, Acoustic insulation should be selected where sound resistance is the primary goal, rather than thermal.

Our acoustic insulation roll collection features premium products from Knauf, Rockwool, and Isover - three manufacturers at the forefront of British insulation technology. Each product in our range has been carefully selected for its proven performance in meeting and exceeding Part E Building Regulations requirements, ensuring your projects achieve the necessary sound insulation standards.

Knauf Earthwool Acoustic Roll represents cutting-edge glass mineral wool technology, manufactured using their innovative ECOSE® plant-based binder system. With manufactured density exceeding 10kg/m³, these rolls are specifically tested with major plasterboard brands to achieve Part E compliance, making specification simple and reliable.

Rockwool acoustic solutions harness the natural properties of volcanic rock to create exceptionally dense mineral wool products. Products like Rockwool RW45, Rockwool Flexi, and Rockwool RW3 offer superior mass per cubic metre compared to standard insulation, delivering enhanced sound absorption where it matters most.

Isover acoustic rolls combine decades of manufacturing excellence with contemporary performance requirements, offering consistent quality and reliable acoustic performance across residential and commercial applications.

Why Acoustic Insulation Roll is Essential for Your Project

Modern building standards recognise that acoustic insulation is no longer optional but obligatory, with specific soundproofing levels mandated for residential buildings. Whether you're working on new construction, conversions, or renovation projects, proper sound insulation protects occupant wellbeing whilst ensuring regulatory compliance.

Acoustic insulation roll works by absorbing and dampening sound waves, reducing noise transmission between spaces. The flexible mineral wool construction allows these products to fill cavities completely, eliminating the air gaps that can compromise acoustic performance. This comprehensive approach addresses both airborne and impact sound transmission, creating genuinely effective sound barriers.

Technical Specifications That Deliver Results

Our acoustic insulation rolls are specifically sized at 600mm width to fit perfectly between studs in modern stud walls, ensuring efficient installation without waste. Available in thicknesses including 25mm, 50mm, 75mm, and 100mm, you can select the optimal density for your specific cavity depth and acoustic requirements.

The mineral wool construction provides exceptional versatility. These products are fire-resistant, flexible, and easy to cut, making them ideal for both professional tradespeople and DIY enthusiasts. The non-combustible properties contribute to overall building safety, whilst the flexible nature ensures perfect cavity filling even in irregular spaces.

Professional Installation Guidance from Our Technical Team

Achieving optimal acoustic performance requires more than quality materials—proper installation technique is crucial. Simply roll out the insulation evenly between joists or studs in walls, floors, or ceilings, ensuring it fits snugly without gaps. However, our technical support goes far beyond basic installation advice.

Our experienced team provides comprehensive project guidance, from initial material specification through to completion testing requirements. We understand that acoustic testing has become compulsory for residential projects not constructed using Robust Details, and we'll help ensure your chosen materials and installation approach meet these demanding standards.

Meeting Building Regulations with Confidence

Current regulations demand minimum 45 dB (DnTw+Ctr) airborne sound insulation for party floors and dividing walls in new builds, with different requirements for conversions and internal partitions. Our acoustic insulation roll products are specifically designed to meet these exacting standards when properly specified and installed.

We don't just supply materials—we provide the technical expertise to ensure your project succeeds. From U-value calculations to condensation risk assessment, our comprehensive support services help you navigate the complex requirements of modern building standards whilst achieving exceptional acoustic performance.
