The Alpha Chem Acoustic Intumescent Sealant White 295ml is a high-performance, water-based acrylic sealant designed to provide both fire protection and acoustic insulation in construction joints and service penetrations. When exposed to high temperatures, it expands (intumesces) to form a robust fire-resistant barrier, helping to prevent the spread of flames and smoke. Its excellent acoustic properties reduce sound transmission, making it ideal for use in walls, floors, and partition systems where noise control is essential. Easy to apply with a standard cartridge gun, it offers strong adhesion to common building materials such as concrete, plasterboard, metal, and wood, while maintaining flexibility to accommodate movement. The white finish ensures a clean, professional appearance, suitable for visible applications in both residential and commercial environments.
Alpha Chem Acoustic Intumescent Sealant White 295ml is a high-performance, fire-rated sealant designed to provide both acoustic insulation and fire protection in construction joints and gaps. This easy-to-apply, water-based sealant expands when exposed to high temperatures, helping to prevent the spread of fire and smoke while maintaining a flexible seal under normal conditions. Ideal for sealing around partitions, door frames, service penetrations, and drywall systems, it also delivers excellent sound reduction properties, making it suitable for use in both residential and commercial buildings. Its smooth white finish allows for a neat appearance and can be overpainted once cured, ensuring a clean and professional result.
The Alpha Chem Acoustic Intumescent Sealant White 295ml is a high-quality, one-part acrylic sealant specifically designed for sealing joints, gaps, and service penetrations in walls and floors where both fire resistance and acoustic insulation are required. It is widely used in construction to maintain compartmentation by providing up to 5 hours of fire protection, while also reducing sound transmission and improving airtightness. When exposed to heat, the sealant expands (intumesces) to help block the spread of flames and smoke. However, its applications are generally limited to internal use only, particularly in low-movement joints and gaps up to around 50mm, and it is not suitable for external environments, areas exposed to constant moisture, or high-movement structural joints.
