    The Rockwool FirePro Ablative Coated Batt is a high-performance fire protection board designed to seal service penetrations through fire-rated walls and floors. Each batt measures 1200 mm × 600 mm × 50 mm, providing 0.72 m² coverage per sheet.

     

    This stone wool insulation slab is factory-coated on one side with a white ablative coating to enhance its fire resistance and seal integrity. It is specifically developed for firestopping applications, offering both fire integrity and thermal insulation around mechanical and electrical service penetrations.

     

    The Rockwool Ablative Coated Batt is a high‑density mineral (stone) wool insulation panel, pre‑coated on one or both faces with a high‑performance ablative fire protection coating. It is designed specifically for use in voids, service penetrations, head‑of‑wall seals and general fire‑stopping applications within fire‑rated walls and floors. It also offers additional benefits in terms of air‑tightness, smoke sealing and acoustic insulation.

     

    Specifications

    • Product: Rockwool Ablative Coated Batt
    • Dimensions: 1200mmx600 mmx50 mm
    • Coverage: 0.72 m2 per board
    • Core material: High‑density stone wool with ablative coating on both faces.
    • Fire‑resistance (single 50mm thickness): Up to 2 hours integrity and insulation — dependent on aperture, services and system details.
    • Air leakage / smoke seal performance: Tested, e.g., the datasheet shows air‑leakage figure of 0.8 m³/h/m² for some configurations.

     

    Performance

    Head‑of‑wall testing: up to Rw ≈ 48 dB for two batts.

    With services (pipe/tray) in concealed cavity: up to Rw ≈ 52 dB for two batts

     

    Features and Benefits

    • Pre‑coated ablative surface for enhanced fire performance.
    • Non‑combustible stone wool core (Euroclass A1 rating) delivering excellent insulation and fire resistance.
    • Designed for use in complex services penetrations, voids, head of wall, blank seals and face‑fixed applications.
    • Good acoustic and air‑tightness performance (reduces sound transmission, smoke/air leakage).
    • Easy to cut and install; lightweight relative to many fire‑boards; adaptable to irregular apertures.
    • Helps reinstate fire compartmentation where services penetrate walls/floors — maintaining fire integrity & insulation.
    • Supports acoustic separation and reduces sound transfer via services or voids, helping compliance with building regulations.
    • Provides an air‑seal barrier which assists smoke containment and helps building ventilation/air‑tightness strategy.
    • Using a known manufacturer and tested system gives confidence in product performance and specification compliance.
    • Versatile for various substrates and applications, reducing need for bespoke or complex fire‑stop assemblies.

     

    Applications

    • Sealing multi‑service penetrations in fire‑rated partitions (walls/floors).
    • Head‑of‑wall sealing (top of wall voids) in compartment walls.
    • Blank seal application (unused aperture) in fire‑rated masonry or stud walls.
    • Face‑fixed applications into floor slab voids or service ducts.
    • Fire‑ and acoustic‑barrier in large framed service voids (e.g., mechanical risers) and flexible wall systems.

     

    Installation

    Key steps (site installer must follow manufacturer’s installation guide):

    • Ensure aperture/void is clean, free of debris and dust.
    • Cut batt to size to make a snug fit into aperture or against substrate.
    • For services (pipes, trays, cables), cut batts appropriately to fit and ensure correct orientation.
    • Apply a bead of recommended acoustic/intumescent sealant around the perimeter of the batt and around services penetrating the batt.
    • Insert batt into aperture and ensure full contact with surrounding edges; infill any gaps larger than 15 mm.
    • On the exposed side(s), apply ablative coating or touch‑up as required where edges/cuts are exposed.
    • Ensure services are adequately supported so no load transfers through batt (because batt is not intended as load bearing).
    • For specific assemblies or system details, refer to manufacturer standard details and tested drawings.

     

    Important installation notes:

    Not to be used as a structural or load‑bearing seal — if load bearing is required use alternative product (e.g., Rockwool Firestop Compound) as specified.

    Ensure the full fire‑stop system (batt + sealant + supporting materials) is installed in accordance with test certificate and manufacturer details.

    Any deviations from tested configurations (e.g., different thickness, different substrate, different services) need to be checked with manufacturer or fire consultant.

     

    Certifications

    • Tested to BS EN 1366‑3:2009 (penetration seals) and BS EN 1366‑4:2006 (linear joint seals) as part of the FirePro system.
    • Classified in accordance with BS EN 13501‑2.
    • CE Marked under EAD 350454‑00‑1104.
