CASE 5 Deployable Draft Curtains and Closely Spaced Sprinklers McKEON from www.mckeondoor.com
Introduction
Draft curtains are a crucial component of any building's fire safety system. These curtains prevent the spread of smoke and flames by compartmentalizing a building into fire zones. The International Building Code (IBC) of 2015 outlines the regulations governing the installation and use of draft curtains in commercial and high-rise buildings. In this article, we'll explore the requirements for draft curtains under the IBC 2015.
What is a Draft Curtain?
A draft curtain is a flexible barrier that hangs from the ceiling to divide a large space into smaller fire zones. It is made of fire-resistant materials, such as fiberglass or asbestos, and is designed to prevent smoke and flames from spreading throughout a building. Draft curtains are typically used in spaces with high ceilings, such as atriums, theaters, and assembly areas.
IBC 2015 Requirements for Draft Curtains
The IBC 2015 outlines several requirements for the installation and use of draft curtains. These include:
1. Placement
Draft curtains must be placed at the perimeter of each fire zone, as well as any openings between fire zones. They must be hung from the ceiling and extend to within 18 inches of the floor.
2. Materials
Draft curtains must be made of fire-resistant materials that meet the requirements of ASTM E84 or UL 723. The materials must be tested and approved by a recognized testing agency.
3. Operation
Draft curtains must be automatically activated by the building's fire alarm system. They must also be able to be manually activated by a switch located at the building's fire command center.
4. Maintenance
Draft curtains must be inspected and tested on a regular basis to ensure that they are in good working condition. Any defects or damage must be repaired immediately.
Benefits of Draft Curtains
Draft curtains provide several benefits for building owners and occupants. These include:
1. Fire Safety
Draft curtains are an essential part of a building's fire safety system. They prevent the spread of smoke and flames, which can save lives and reduce property damage.
2. Cost Savings
Draft curtains can help reduce the cost of fire protection systems by allowing buildings to be compartmentalized into smaller fire zones. This can reduce the number of sprinklers and other fire protection devices required.
3. Design Flexibility
Draft curtains can be customized to fit the design and architecture of a building. They can be made in a variety of colors and materials to blend in with the surrounding decor.
Conclusion
Draft curtains are an essential component of any building's fire safety system. The IBC 2015 outlines the requirements for the installation and use of draft curtains in commercial and high-rise buildings. By following these regulations, building owners can ensure that their occupants are safe in the event of a fire.
