Firestop Batt – Ablative Coated – Walls

Product Overview

Introducing a high-performance ablative coated batt measuring 50mm thick and 1200mm × 600mm in size. This high-density stone-wool fire-stopping slab is factory-coated on both faces with a water-based ablative sealant. It's specifically designed to reinstate fire resistance and acoustic integrity of walls and floors where services penetrate compartment lines.

The combination of a non-combustible mineral wool core and ablative coating provides up to two hours of fire resistance when installed as part of a tested system. The coating effectively prevents the passage of smoke and flames, while the slab maintains its insulation and dimensional stability under fire exposure.

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 of 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 an ablative coating.
• Service sealing: Apply additional coating or intumescent sealant around penetrations as required.
• Finish: Smooth coating surface to ensure a uniform seal; allow to dry before exposure to service conditions.

This product is manufactured to meet high standards, offering significant fire resistance and acoustic control. Suitable for various applications across construction and building maintenance projects.
