It is specifically designed for sound insulation in new build and retrofit internal wall and floor applications. The roll has a manufactured density in excess of 10kg/m³ to meet building regulations and has been tested with all major brands of plasterboard to achieve compliance with Part E building regulations. It is designed to fit between studs to close joints, reducing the potential for unwanted gaps and maximising sound insulation performance. The ready-cut rolls ensure quick and easy installation, while the longer rolls facilitate efficient handling, transport, and storage. This acoustic glass mineral wool roll is suitable for stud partitions and separating floors, and can be used for timber and metal stud walls at 600mm centres. The 100mm thickness delivers maximum acoustic control in high-spec partitions. It is sized for friction fitting between timber and metal studs at 600mm centres, reducing airborne sound transmission in separating walls, intermediate floors, and internal partitions. Supplied 1200mm wide and pre-perforated for splitting into 2 x 600mm widths, it enables straightforward installation between standard studs or joists. With a manufactured density in excess of 10kg/m³, it also provides effective acoustic absorption while contributing to thermal resistance and fire safety. Classified Euroclass A1 non-combustible, it supports compliance in wall and floor systems. At 100mm thick, it is designed for deep cavity constructions, achieving maximum acoustic performance with additional thermal efficiency.

Product Information
Full details
This guide is for builders, contractors, and DIY enthusiasts looking to enhance sound insulation in internal walls and floors. The Knauf Insulation Acoustic Roll - 100mm offers superior sound dampening for new builds and retrofits, leveraging ECOSE® Technology. A key benefit is its A1 non-combustible classification, contributing to fire safety. However, it's specifically designed for friction-fitting within standard stud spacings and may require additional support for non-standard constructions.

FAQs
What is ECOSE® Technology?
ECOSE® Technology is Knauf Insulation's advanced binder system that uses no added formaldehyde or phenol. It contributes to improved indoor air quality and reduces the environmental impact of the insulation material.
Is this product suitable for external walls?
This specific Acoustic Roll is primarily designed for internal walls and floors for sound insulation purposes. For external walls, different types of insulation with specific thermal and weatherproofing properties are typically required.
Can I cut this roll to fit non-standard stud spacing?
Yes, the roll can be cut to size. However, the product is optimized and tested for 600mm centres. For other spacings, ensure a tight fit without compression or gaps to maintain acoustic performance.
What PPE should I wear when handling this insulation?
It is recommended to wear long-sleeved clothing, gloves, eye protection, and a dust mask to prevent skin irritation and dust inhalation.
How does the 100mm thickness contribute to performance?
The 100mm thickness provides a greater mass and depth within the cavity, which is crucial for absorbing a wider range of sound frequencies and significantly reducing airborne sound transmission compared to thinner insulation options.
Does this insulation also provide thermal benefits?
Yes, while primarily designed for acoustic performance, glass mineral wool does offer thermal resistance (R-value), contributing to the overall thermal efficiency of the building element.
What is the Euroclass rating for this product?
This product is classified as Euroclass A1 non-combustible, which is the highest possible rating for fire performance.
Troubleshooting
Difficulty achieving friction fit
Ensure studs are at the correct 600mm centres. If slightly loose, consider adding a small wooden batten or friction strip. If too tight, ensure no obstructions.
Gaps in insulation around services (pipes, cables)
Carefully cut small pieces of insulation to fill these gaps, ensuring a snug fit to prevent sound flanking paths.
Dust during installation
Wear appropriate PPE (dust mask, gloves, eye protection). Ensure good ventilation in the work area. Use sharp cutting tools for cleaner cuts.
Reduced acoustic performance
Check for any unintended gaps or voids in the insulation layer or around the perimeter of the wall/floor. Ensure plasterboard is sealed correctly.
Pros and Cons
Pros
Excellent sound insulation performance for internal partitions and floors.
A1 non-combustible rating enhances fire safety compliance.
Easy to install due to friction-fit sizing and pre-perforations.
ECOSE® Technology promotes a healthier indoor environment.
Versatile use in various wall and floor constructions.
Contributes to thermal resistance alongside acoustic benefits.
Cons
Primarily designed for 600mm stud centres; may require cutting or adjustment for other spacings.
Requires appropriate Personal Protective Equipment (PPE) during installation.
Dust generation during cutting or handling can occur.
Performance is dependent on correct installation without gaps.
Setup, Compatibility & Care
Setup:
Measure & Cut: The rolls are supplied 1200mm wide and pre-perforated to split easily into two 600mm widths. Measure the cavity height and cut the roll to length if necessary. Use a sharp knife or insulation saw for clean cuts.
Install: Carefully insert the cut insulation between the studs or joists. The material is designed for a friction fit, meaning it should stay in place without mechanical fixings. Ensure there are no gaps around pipes or cables.
Completing the Wall/Floor: Proceed with plasterboard installation as per the system manufacturer's guidelines, ensuring a good seal around edges.
Compatibility:
The Acoustic Roll - 100mm is designed to fit between standard timber and metal studs at 600mm centres.
It has been tested for compliance with Part E building regulations when used with common plasterboard systems. Always refer to specific system details for guaranteed compliance.
Care:
Handling: Wear appropriate PPE, including gloves, eye protection, and a dust mask, during handling and installation to avoid skin irritation and dust inhalation.
Storage: Store rolls in a dry, protected area, ideally under cover, to maintain their integrity and performance.
Cleaning: The product itself requires no cleaning once installed. Ensure the surrounding area is kept clean during the construction process.
