Construction and Composition
The Astro DS Duct Sleeve is composed of a flexible and durable intumescent material that reacts to high temperatures. This material is encased in a robust, yet lightweight, metal sleeve. The intumescent material within the sleeve is designed to expand significantly when exposed to heat, usually around 200°C (392°F). This expansion effectively seals the duct, closing off the pathway that fire and smoke could use to spread.
Installation and Application
The sleeve is designed for easy installation, typically around ductwork where it passes through a fire-rated barrier. It can be installed during the construction phase or retrofitted into existing systems, making it versatile for various building types, including residential, commercial, and industrial structures. The installation process generally involves sliding the sleeve over the duct before it is passed through the penetration, ensuring that the sleeve fits snugly against the barrier surface.
Performance and Certification
The Astro DS Duct Sleeve is tested to rigorous international fire safety standards, such as EN 1366-1, and is certified for use in various fire-rated walls and floors, including concrete, brick, and gypsum. Depending on the specific application, the sleeve can provide up to 120 minutes of fire resistance, meaning it can maintain the integrity of the fire barrier for two hours under test conditions. This level of protection is critical in high-risk areas where the spread of fire could have catastrophic consequences.
Advantages and Features
- High Expansion Rate: The intumescent material expands up to 25 times its original thickness, ensuring a tight seal around the duct.
- Versatile Application: Suitable for use with a wide range of duct sizes and types, including rectangular and circular ducts.
- Ease of Installation: Designed for quick and simple installation, minimizing disruption during the construction or retrofit process.
- Compliance: Meets stringent fire safety standards and building regulations, ensuring that it is a reliable component in any fire protection strategy.
- Maintenance-Free: Once installed, the sleeve requires no maintenance, providing long-lasting fire protection without the need for regular inspections or replacements.
Use Cases
The Astro DS Duct Sleeve is ideal for use in buildings where HVAC ducting penetrates fire-rated barriers. Common applications include:
- Commercial Buildings: Office buildings, shopping centers, and hotels where maintaining compartmentalization is critical.
- Residential Buildings: High-rise apartments and multi-family dwellings where fire containment is essential for occupant safety.
- Industrial Facilities: Factories and warehouses with extensive ductwork that could serve as a conduit for fire and smoke spread.
In summary, the Astro DS Duct Sleeve is a highly effective, easy-to-install solution for ensuring that HVAC duct systems do not compromise the fire safety of a building. By expanding to seal off ducts during a fire, it plays a crucial role in protecting lives and property.
