We'll be sharing some FAQs throughout the coming months, starting with a common question we hear about the selection of fire dampers. Learn more below and be sure to visit our NEW FAQ page on the website for helpful information.
When do I use a 1.5-hour fire damper, and when do I use a 3-hour fire damper?
The selection of a 1.5-hour fire damper or a 3-hour fire damper depends on the specific fire protection requirements of the building and the location of the damper within the HVAC system.
Fire dampers are designed to prevent the spread of fire and smoke through ductwork and openings in fire-rated barriers. The numerical value (e.g., 1.5 hours, 3 hours) represents the damper's fire-resistance rating, indicating the duration of time the damper can withstand exposure to fire before it fails.
Visit our FAQ page to read some general guidelines about when and where to use a 1.5-hour fire damper versus a 3-hour fire damper.
