The Rockwool RWA45 Acoustic Insulation Slab is a home improvement insulation slab designed to improve thermal and acoustic performance while meeting strict fire standards. Homeowners and studio builders can expect quieter rooms and greater confidence during renovations. Will the coverage and physical properties suit common retrofit and acoustic projects?
⚡ At a Glance
- • Acoustic Performance: Effective at reducing airborne noise and useful for bass-trap style treatments
- • Best for: Homeowners, builders and studio installers needing thermal and sound control
- • Not ideal for: Applications requiring a full vapour barrier or exposed external cladding
Slabs deliver thermal and acoustic insulation with an A1 Euroclass fire rating. Water-repellent finish helps maintain performance in damp-prone areas.
Quieter Rooms - with rockwool slab construction
Dense fibrous composition captures and dissipates airborne sound energy, reducing reverberation. Panel form allows placement in walls, ceilings and bespoke studio panels.
Improved room clarity and lower noise transmission makes small rooms and practice spaces noticeably quieter. Useful for treating rear-wall reflections and control of mid-bass energy.
Better Heat Retention - thanks to insulating slab properties
Interlocking fibres trap pockets of air to slow conductive and convective heat transfer through cavities and partitions. Slab thickness contributes to thermal resistance in common wall builds.
More stable indoor temperatures reduce heating demands and damp draughts in retrofit projects. Suited to cavity insulation where combined acoustic and thermal performance is required.
Greater Fire Safety - with A1 Euroclass fire rating
Certified A1 under the Euroclass system, indicating the highest classification for non-combustibility and minimal contribution to fire. Behaviour under fire is assessed according to European testing standards.
Adds a layer of passive fire protection to partitions and ceilings, improving overall safety in domestic and studio installations. Suitable where compliance with strict fire classification is requested.
