The Intumescent Fire & Acoustic Sealant 900ml – Fireproof & Soundproof is a professional-grade sealing solution designed to protect buildings against both fire and noise. This advanced sealant expands when exposed to high heat, sealing gaps and joints to block the spread of fire, smoke, and toxic gases. At the same time, it remains flexible after curing, helping to reduce sound transmission through walls, floors, and partitions.
This makes it an essential product for modern construction, renovations, and safety upgrades in residential, commercial, and industrial buildings. It is commonly used around service penetrations, door frames, window frames, plasterboard joints, and cable or pipe openings where fire and sound can easily pass through small gaps.
The 900ml cartridge provides excellent coverage for large projects and is compatible with standard sealant guns. It bonds strongly to most building materials, including concrete, brick, plasterboard, metal, and wood. Once applied, it cures to form a durable, flexible seal that maintains its fire-stopping and acoustic performance over time.
Fire and smoke spread rapidly through unsealed gaps and joints in buildings, putting lives and property at risk. At the same time, noise easily travels through these same gaps, reducing privacy and comfort.
This intumescent fire and acoustic sealant solves both problems by sealing openings and expanding when exposed to heat, creating a fire-resistant barrier while also blocking sound and vibration. It improves safety, helps meet building regulations, and creates quieter living and working spaces.
Standard sealants are not fire-rated and can melt, crack, or shrink in high temperatures. Cheap fillers also harden over time, losing their ability to block sound. This trade-grade intumescent sealant is specially formulated to resist fire, expand when needed, and remain flexible for long-term acoustic performance. It offers reliable protection that low-cost alternatives simply cannot provide.
This sealant is ideal for sealing service penetrations, fire-rated walls and floors, door and window frames, plasterboard joints, electrical boxes, and pipe openings. It is widely used in UK homes, flats, offices, schools, and commercial buildings to meet fire and sound insulation standards.
