Application Instructions
- Measure stud or joist spacing (typically 600 mm centres) to select correct roll width.
- Cut insulation to length using a sharp utility knife.
- Friction-fit the roll tightly between studs or joists to eliminate gaps.
- Ensure continuous coverage for optimal acoustic performance.
- Protect the insulation from moisture during storage and installation.
Coverage Calculator
- Coverage per roll depends on selected thickness: 11–15.6 m². Calculate by dividing total project area by roll coverage.
Suitable Applications
- Internal partition walls
- Separating walls and floors
- Timber and metal stud partitions
- Residential and commercial acoustic insulation
- Floor insulation in timber joist systems
Compatibility & Limitations
- Compatible with timber studs, metal stud partitions and joisted floors.
- Not suitable for permanent exposure to external weather conditions.
- Must be kept dry prior to installation to maintain performance.
Safety & Handling
- Wear gloves, long sleeves and a dust mask when cutting insulation.
- Store rolls indoors or under cover, off the ground.
- Do not leave exposed to elements after installation.
Frequently Asked Questions
Acoustic Roll is designed to reduce sound transmission in internal and separating walls, floors, and stud partitions. It improves acoustic comfort in homes and commercial spaces by absorbing airborne noise and preventing sound from moving between rooms or floors.
Yes. Acoustic Roll is classified as Euroclass A1, which is the highest non-combustible fire rating in Europe. This ensures excellent fire safety performance, making it suitable for residential, commercial, and industrial applications where flame spread resistance is critical.
Absolutely. Acoustic Roll is specifically designed for friction fitting into 600 mm metal or timber studs. Its flexibility ensures tight fitting with no gaps, maximising sound insulation performance and overall acoustic absorption inside partition systems.
The ideal thickness depends on application: 50 mm for light partitions, 75 mm for improved performance, and 100 mm for maximum noise reduction. Thicker rolls provide higher NRC values and better sound absorption within the wall or floor structure.
Yes. Acoustic Roll is rot-proof, non-hygroscopic, and does not sustain mould, fungi or bacteria. It does not absorb moisture and remains dimensionally stable, ensuring long-term indoor air quality and performance when installed in dry, protected environments.
Yes. Manufactured with ECOSE® Technology, Acoustic Roll contains no added formaldehyde and has zero ozone depletion and global warming potential. Its binder is made from bio-based renewable materials, making it an environmentally responsible insulation choice.
It is extremely easy to handle, cut, and friction-fit between studs and joists. Lightweight rolls allow faster installation, and the pre-cut 600 mm widths align perfectly with standard framing, reducing labour time and improving acoustic consistency.
Yes. Acoustic Roll is suitable for timber joist floors where sound insulation is required between rooms. It absorbs airborne noise and helps reduce impact sound transfer when combined with appropriate floor finishes.
Acoustic Roll has negligible vapour resistivity; however, whether you require a vapour barrier depends on building regulations and construction design. Typically, vapour control layers are used where moisture migration must be restricted in specific systems.
Store rolls indoors or under cover, elevated off the ground, and in their original packaging until installation. Polythene wrapping offers short-term protection only. Avoid exposing the insulation to rain or weather to preserve performance.
