What is Rockwool Firestop High Expansion Intumescent Sealant?

Firestop High Expansion Intumescent Sealant is a versatile, high-performance sealant designed to provide passive fire protection in various construction applications. It is available in 310ml cartridges, making it easy to apply with a standard sealant gun. The sealant is formulated to expand when exposed to high temperatures, effectively sealing gaps and preventing the spread of fire and smoke.

Features and benefits of Rockwool Firestop High Expansion Intumescent Sealant

  • Fire resistance: The sealant offers excellent fire protection performance, providing up to 4 hours of fire resistance, depending on the specific application and installation. This helps maintain the structural integrity of buildings during a fire and meet stringent fire safety regulations.
  • Intumescent properties: When exposed to high temperatures, the sealant expands significantly, effectively sealing gaps and preventing the spread of fire and smoke through the building. This characteristic makes it ideal for use around service penetrations, such as pipes, cables, and ducts, as well as for sealing joints in fire-rated walls, floors, and ceilings.
  • Adhesion: Firestop High Expansion Intumescent Sealant has excellent adhesion properties, making it suitable for use on a wide range of substrates, including concrete, masonry, steel, and gypsum boards. It forms a strong bond that remains flexible, accommodating movement and ensuring a long-lasting seal.
  • Easy application: The sealant is available in 310ml cartridges, which can be easily applied using a standard sealant gun. It has a smooth consistency, allowing for precise application and a clean finish.
  • Acoustic performance: In addition to fire protection, the sealant provides good acoustic insulation, contributing to a comfortable and quiet environment within the building.
  • Compatibility: Firestop High Expansion Intumescent Sealant is compatible with most building materials and can be painted or covered with other decorative finishes once cured, providing a seamless appearance.
