Square Cut Penetration Fire Stopping Solution
Description

The Rothoblaas products MASS and Graphit Foam work collectively to provide an effective fire-stopping solution for square cut penetrations.

  • MASS is an intumescent brick that expands upon exposure to fire, forming an insulating barrier that prevents the spread of flames.
  • Graphit Foam is a two-component polyurethane foam enhanced with graphite, which expands significantly to fill gaps and cracks, further enhancing the fire resistance and sealing capabilities.

Together, they ensure comprehensive protection by blocking heat, flames, and smoke through penetrations.

The Rothoblaas MASS and Graphit Foam fire-stopping system is suitable for sealing mechanical and electrical penetrations, including cables, pipes, and mixed penetrations, in various substrates such as timber, concrete, masonry, and gypsum board, making it ideal for both commercial and residential buildings.

A proven solution, delivering unparalleled performance by rapidly expanding and sealing penetrations to provide up to EI60 fire protection on CLT floors and EI120 fire protection on CLT walls against fire, smoke, and toxic gases.

Key Features
  • Enhanced Fire Resistance: MASS expands upon exposure to fire, forming an insulating barrier, while Graphit Foam expands up to 3-5 times its original volume, filling gaps and cracks effectively.
  • Comprehensive Sealing: The combination ensures that all penetrations, including small cracks and openings, are sealed, preventing the spread of flames, smoke, and toxic gases.
  • Durability and Reliability: Provides long-lasting fire protection, maintaining their integrity and performance over time.
  • Versatility: Suitable for various types of penetrations, including cables, pipes, and mixed penetrations in different shapes and sizes.
  • Ease of Application: Both products are easy to apply and can be shaped or moulded to fit specific requirements, making them ideal for construction sites with unknown design specifications. MASS is easily shapeable with a simple cutter, making it ideal for construction sites with unknown design specifications.
  • Maintenance-Friendly: MASS can be easily removed and repositioned if maintenance or changes to the installation are needed.
Scope of Use
  • Mechanical and Electrical Penetrations: Ideal for sealing around cables, pipes, and mixed penetrations in various shapes and sizes.
  • Construction Sites with Unknown Specifications: Easily shape-able and adaptable, making it suitable for sites where design specifications are not fully known.
  • Multiple Penetrating Elements: Effective for crossings with multiple elements, ensuring comprehensive sealing and fire protection.
  • Maintenance and Repositioning: MASS can be easily removed and repositioned, facilitating maintenance and changes to installations.
  • Versatile Applications: Suitable for use in both commercial and residential buildings, providing reliable fire protection across different environments.
Limitations on Use
  • Not suitable for submerged or constantly wet environments.
  • Ensure compatibility with the specific substrates being used, as some materials may not adhere properly or provide the required fire resistance.
  • While Graphit Foam offers some flexibility, excessive movement in joints can compromise the integrity of the fire stopping system.
Statement of Building Code Compliance

Rothoblaas Fire products are designed and tested to meet the stringent requirements of the New Zealand Building Code for fire safety. These products comply with the relevant standards, including:

  • NZBC Clause C3 (Fire affecting areas beyond the fire source): These products provide effective fire stopping solutions, preventing the spread of fire, smoke, and toxic gases through penetrations in fire-rated walls and floors.
  • NZBC Clause B2 (Durability): The materials used in MASS, Fire Foam, and Fire Silicone are durable and maintain their fire-resistant properties over the intended lifespan of the building.
  • NZBC Clause F2 (Hazardous building materials): These products are safe to use and do not release harmful substances under normal conditions of use.

The combination of MASS and Graphit Foam has been tested and certified to international standards such as EN 13501-1 and EN 13501-2, ensuring their performance in fire-rated assemblies. This compliance ensures that these products provide reliable and effective fire protection in accordance with New Zealand’s building regulations.

Other Performance Attributes

MASS:

  • Reusability: Can be removed and repositioned if maintenance or changes to the installation are needed.

Graphit Foam:

  • No Melting or Dripping: When exposed to high heat, the foam does not melt or drip, preventing flame spread.
  • Char Layer Formation: Creates a char layer that dramatically reduces heat release rate, mass loss, smoke generation, and toxic gas emission.

These attributes enhance the overall effectiveness and versatility of the fire-stopping solution, providing comprehensive protection and additional benefits beyond fire resistance.

Warranty & Maintenance

Warranty:

  • Material Defects: The products are warranted to be free from defects in materials and workmanship.
  • Performance Guarantee: The products are guaranteed to perform as specified under normal conditions of use.
  • Duration: The specific duration of the warranty can vary, so it is recommended to refer to the product documentation or contact Rothoblaas directly for detailed information.

Maintenance Requirements:

  • Regular Inspections: Periodically inspect the fire-stopping installations to ensure they remain intact and effective.
  • Environmental Conditions: Ensure that the products are not exposed to conditions beyond their specified temperature and humidity ranges.
  • Repair and Replacement: If any damage or degradation is observed, repair or replace the affected areas promptly to maintain fire protection integrity.
  • Cleaning: Keep the areas around the fire-stopping installations clean and free from debris that could compromise their effectiveness.
