The ARC Intumescent & Acoustic Selant 310ML is a premium fire-rated acrylic sealant that combines outstanding fire protection with effective sound insulation in a single easy-to-apply solution. Designed to provide up to 4 hours of fire resistance, it expands when exposed to high temperatures to help prevent the spread of fire and smoke through joints and gaps.
Perfect for both residential and commercial construction projects, this intumescent sealant is ideal for sealing irregular or uneven gaps around service penetrations, door frames, window sills, fire-rated partitions and fire protection boards. Its acoustic properties also help minimise airborne sound transmission, making it an excellent choice where both fire safety and noise reduction are required.
