What is Furrdowns?
Furrdowns are lowered sections built below a ceiling or around a wall to cover ductwork, pipes, wiring, or other items that need to stay out of sight.
Definition
Purpose
Furrdowns give contractors extra space for routing building services without leaving them exposed. They are often used where a large duct or pipe cannot fit between the existing framing members. In kitchens, a furrdown can close the gap above wall cabinets. In other areas, it can create a path for HVAC ducts or help transition between different ceiling heights.
Examples of Use
- Kitchen Cabinets: A furrdown above the upper cabinets can cover the open space between the cabinets and ceiling and may also hide range hood ductwork or wiring.
- HVAC Ducts: A fur-down chase can provide room for supply or return ducts when the available space between floor or ceiling framing is too shallow.
- Plumbing Lines: Pipes that cannot be routed through the framing can sometimes be enclosed inside a furrdown.
- Electrical Work: Wiring, conduit, and other electrical components may be concealed within a framed ceiling drop where permitted.
- Hallways: Furrdowns can run along a hallway to provide a route for ducts or other services while keeping the main ceiling line intact.

Notes
- Furrdowns are commonly framed with wood members or metal studs and finished with drywall.
- The size of a furrdown depends on what needs to pass through it and the clearance required around those components.
- Plan a fur-down duct chase with the HVAC layout before framing begins.
- The top of a furrdown may need to be sealed when the space connects to an attic or other unconditioned area.
- Furrdowns are generally used as enclosures and should not be assumed to carry structural loads unless specifically designed for that purpose.
- Furrdown takeoffs may include framing, drywall, insulation, fasteners, corner bead, joint compound, and other materials needed to build and finish the enclosure.
