Rockwool RW3

Rockwool RW3 is a tough, semi-rigid stone wool slab that performs excellently in keeping heat in, blocking noise, and stopping fire in its tracks. Thanks to its low thermal conductivity of just 0.034 W/m·K and a top-tier A1 non-combustible rating, it outperforms most flexible insulations.

What is Rockwool RW3 Slabs?

Rockwool RW3 insulation slabs are natural stone wool products processed into either rigid or semi-rigid panels. RW3 insulation, like other mineral wool products,  combines reliable heat control with outstanding sound absorption.

What is Rockwool Acoustic RW3 Used for?

RW3 is renowned due to its versatility. It is versatile enough to be installed in places like:

• Living rooms, entertainment rooms, and bedrooms to minimise noise transfer between walls.
• Kitchens and bathrooms for moisture resistance and improved thermal insulation, provided it is properly enclosed.
• Ceilings and floors to reduce impact and airborne sound between levels.
• Entryways, corridors, and staircases to reduce noise and create quiet environments.
• Commercial and industrial environments where noise reduction and fire safety are a priority.

It’s excellent for partitions and separating walls, intermediate floors, and as part of flat roof systems beneath waterproof membranes.

Benefits of RW3 Acoustic Insulation Slabs

RW3 Acoustic insulation stands out because of its:

• Thermal efficiency: Helps maintain comfortable indoor temperatures all year round.
• Superior sound absorption: RW3 performs excellently in containing sound within a confined space or blocking sound transmission between rooms.
• Moisture resistance: It is vapour-permeable but water-repellent, resisting rot, mould, and microbial growth.
• Fire resistance: RW3 is rated Euroclass A1, meaning it is non-combustible and complies with Approved Document B requirements.
• Sustainability: Made from naturally occurring volcanic rock with high recycled content.
• Installation ease: Rockwool RW3 insulation is light enough to carry, cut, and install.

FAQ:

What is Rockwool RW3?

Rockwool RW3 panels are mineral wool slabs commonly used for wall, floor, ceiling, and roof insulation. The high Rockwool RW3 density and stone wool fibres trap air, reducing heat and sound transfer to lend the material its highly desirable insulation properties.

How do I install Rockwool RW3?

Start by measuring the cavity, then cut your RW3 slab to fit or slightly oversize for a snug fit. Fix the slab firmly, taking care to leave no gaps. In framed constructions, simply friction-fit it into the space. Otherwise, use the appropriate fasteners. Finish with plasterboard or decorative panels, as applicable.

Always remember to wear gloves, a mask, and protective clothing when handling Rockwool RW3 slab.

Is Rockwool RW3 waterproof?

No, RW3 is not waterproof. However, it is highly water-repellent and moisture-resistant. Its stone wool fibres do not readily absorb water, meaning they won’t rot or support mould growth.
