What is the depth of furring channel?

The depth of a furring channel typically depends on the type and application. Here are the common sizes:

Standard Furring Channel Depths (U.S. and Metric):

• 7/8 inch (≈ 22 mm): Most common size for ceiling or wall furring.

• 1-1/2 inches (≈ 38 mm): Used when more space is needed for insulation, wiring, or leveling.

Usage Considerations:

• Ceilings: 7/8" is common for suspended ceiling systems.

• Walls: 7/8" or 1-1/2" may be used depending on soundproofing, thermal insulation, or leveling needs.
