Product Information

Full details

The Knauf Insulation Acoustic Roll - 25mm is designed for builders and renovators seeking to improve sound insulation in internal walls and floors. Its key benefit is reducing airborne sound transmission, contributing to quieter living or working spaces. A caveat is its 25mm thickness, which is best suited for shallow cavities requiring only modest acoustic improvement.

Extended Product Information

FAQs

What is the primary purpose of this 25mm acoustic roll?

The primary purpose is to reduce airborne sound transmission in internal walls and floors, offering a basic level of sound insulation, particularly in shallow cavity constructions.

Is this insulation fire-rated?

Yes, it is classified as Euroclass A1, meaning it is non-combustible and offers a high level of fire safety.

Can I use this for thermal insulation?

While it contributes to thermal resistance, its primary design focus is acoustic insulation. For significant thermal performance, thicker insulation products are generally recommended.

What does ECOSE® Technology mean?

ECOSE® Technology refers to the binder system used in the glass mineral wool, which is formaldehyde-free and has a lower environmental impact during manufacturing compared to traditional binders.

How do I install this roll in a metal stud wall?

The process is similar to timber studs. Ensure the roll fits snugly between the metal studs spaced at 600mm centers, avoiding compression or gaps.

Can this product be used in external walls?

This specific product is designed for internal applications and is not intended for use in external walls.

What is the density of this insulation?

The manufactured density is in excess of 10 kg/m³, which is crucial for its acoustic absorption capabilities.

Troubleshooting

Gaps in insulation after fitting

Ensure the roll is cut to size and fits snugly without compression. For larger gaps, consider using smaller offcuts to fill them, ensuring a continuous layer.

Difficulty cutting the insulation

Use a sharp insulation knife or a serrated blade for clean cuts. Ensure the material is laid flat for easier cutting.

Skin irritation after handling

Always wear protective gloves, long sleeves, and eye protection during installation. If irritation occurs, wash the affected area with soap and water.

Pros and Cons

Pros

Effective at reducing airborne sound transmission in internal partitions.
Euroclass A1 non-combustible rating for enhanced fire safety.
Manufactured with ECOSE® Technology for a more sustainable product.
Designed for easy friction fitting into standard stud spacings.
Contributes to thermal resistance and overall building performance.
Tested with major plasterboard brands for compliance with building regulations.

Cons

25mm thickness is only suitable for basic sound control and shallow cavities.
May not provide sufficient acoustic insulation for high-noise environments.
Requires appropriate personal protective equipment during installation.
Primarily for internal use; not designed for external wall applications.

Setup, Compatibility & Care

Setup:

Ensure the stud cavities (timber or metal) are clean and free from debris.
Measure the cavity dimensions. The roll is designed to friction fit between studs at 600mm centers.
Unroll the insulation and cut to size if necessary, ensuring a snug fit without compression.
Carefully place the insulation within the stud cavities, ensuring no gaps are left, especially around services.
Proceed with installing plasterboard or other covering materials.

Compatibility:

Compatible with both timber and metal stud framing systems at 600mm centers.
Designed to work in conjunction with standard plasterboard and other common internal wall and floor construction materials.
Tested with major brands of plasterboard to help achieve compliance with Part E building regulations.

Care:

Store rolls in a dry, protected area, ideally on end or flat to prevent damage.
Avoid excessive moisture, which can degrade performance.
Handle with appropriate personal protective equipment (gloves, eye protection, dust mask) to avoid skin irritation and inhalation of fibers.
Clean up any dust or debris generated during installation using standard cleaning methods.
