Product Overview
Rockwool Ablative Coated Batt measuring 50mm thick and 1200mm × 600mm in size.
High-density stone-wool fire-stopping slab factory-coated on both faces with a water-based ablative sealant. Designed to reinstate fire resistance and acoustic integrity of walls and floors where services penetrate compartment lines.
The combination of non-combustible mineral wool core and ablative coating provides up to two hours’ fire resistance when installed as part of a tested system. The coating prevents the passage of smoke and flames, while the slab maintains insulation and dimensional stability under fire exposure.
Lightweight yet rigid, the batt can be easily cut to shape for complex service penetrations, offering a clean, durable finish once installed. The 50mm thickness is suited to single-layer applications and narrow or moderate-thickness wall constructions.
Features & Benefits
- Non-combustible core: Euroclass A1 stone wool delivers inherent fire resistance and acoustic performance.
- Ablative coating: Factory-applied sealant expands under heat, sealing gaps and restraining flame spread.
- Tested fire performance: Provides up to 120 minutes’ integrity and insulation when installed to approved details.
- Acoustic insulation: High-density structure reduces airborne sound transmission through penetrations.
- Ease of installation: Simple to cut and fit around cables, pipes, and ducts with minimal dust generation.
- Thickness: 50mm slab suitable for single-layer installations in standard partitions and floors.
Applications
- Service penetrations: Restores fire rating around pipes, ducts, and cable trays in walls or floors.
- Compartmentation: Used to seal voids in fire-rated walls, floors, and ceilings.
- Electrical and mechanical services: Compatible with metallic and non-metallic pipes, conduits, and trunking.
- Acoustic control: Reduces noise leakage through service openings in separating structures.
Installation Guidance
- Preparation: Ensure openings are clean, dry, and free from debris before fitting.
- Cutting: Trim batt to fit tightly within the aperture using a long-bladed knife or saw.
- Compression fit: Insert slab under light compression; coat cut edges with Rockwool Ablative Coating.
- Service sealing: Apply additional coating or Rockwool Intumescent Sealant around penetrations as required.
- Finish: Smooth coating surface to ensure uniform seal; allow to dry before exposure to service conditions.
Compliance & Performance
- Material specification: Stone wool to BS EN 13162, coated with factory-applied water-based ablative sealant.
- Fire classification: Euroclass A1 non-combustible core; tested to BS EN 1366-3 and BS EN 1366-4.
- Fire resistance: Up to 120 minutes’ integrity and insulation (system dependent).
- Acoustic performance: Up to 52 dB sound reduction when installed correctly.
- Environmental compliance: Free from CFCs, HFCs, and HCFCs; recyclable stone-wool composition.
- Important note: Fire rating is dependent on the complete system build-up and installation in accordance with Rockwool’s tested details.
