50mm Acoustic Mineral Wool Slabs – 60kg/m³ Soundproofing for Walls, Floors & Ceilings

SilentCloud® StudioCore 45 – 50mm Acoustic Mineral Wool Slabs (60 kg/m³)

Professional Acoustic Infill for Walls, Floors & Ceilings

SilentCloud® StudioCore 45 – 50mm is a high-performance acoustic mineral wool slab engineered specifically for airborne sound absorption inside framed building systems.

Unlike generic insulation products adapted for sound control, StudioCore 45 is acoustically optimised by design — using a controlled 60 kg/m³ density and open fibre structure to deliver predictable, real-world acoustic performance.

Designed for professional installers and serious renovation projects, it forms a critical internal layer in effective soundproofing systems.

Why Choose SilentCloud® StudioCore 45

Acoustic-Optimised Density (60 kg/m³)
Engineered specifically for sound absorption to reduce speech, TV, music and general airborne noise inside stud cavities.

50mm Professional Thickness
Ideal balance of performance and flexibility for timber and metal stud walls, intermediate floors and suspended ceilings.

Open Fibre Structure
Efficiently converts sound energy into heat through internal friction, reducing reverberation and noise transfer.

Fire-Safe Mineral Construction
Manufactured from non-combustible mineral fibres for use in residential and commercial environments.

Installer-Friendly Slabs
Rigid enough to friction-fit securely between studs without sagging, yet easy to cut and handle on site.

Typical Applications

SilentCloud® StudioCore 45 – 50mm is widely used in:

• Stud walls and internal partitions

• Intermediate floors and ceiling voids

• Apartments and party wall upgrades

Acoustic Performance Explained

StudioCore 45 is true acoustic infill, designed to absorb airborne sound energy within framed constructions.

When installed as part of a complete soundproofing system — alongside double plasterboard, resilient bars or acoustic membranes — it significantly improves overall noise reduction by limiting internal reverberation and sound transmission.

This product is engineered for sound, not thermal insulation repurposed for acoustic use.

Installation Guidance

• Cut slabs 5–10 mm oversize for a tight friction fit

• Install directly between studs or joists

• No mechanical fixings required in most applications

• Wear gloves, mask and eye protection when cutting

• Seal surrounding structure for best acoustic results

Frequently Asked Questions

Is this product for soundproofing or sound absorption?
It is designed for airborne sound absorption inside cavities, which is a critical component of effective soundproofing systems.

Can it be used for thermal insulation?
It offers incidental thermal benefits, but it is engineered primarily for acoustic performance.

Is 50mm thick enough for soundproofing?
Yes, 50mm performs excellently in stud walls and ceilings. Thicker systems may be used where enhanced low-frequency control is required.

Is it suitable for residential use?
Yes. It is made from non-combustible mineral fibres and is suitable for both residential and commercial applications.
