Furring refers to thin strips of wood or metal (for fire rating) which are installed on a wall or ceiling surface for later attachment of finish materials. The main purpose for using furring strips is to leveling a finish surface, but making space for insulation, utilities in the wall, and dampness prevention are also benefits.


Furring strips provide a medium for assuring a walls finish surface material is installed straight, plumb, and true. Furring channels may also be utilized to suspend certain types of ceiling tiles.

Wood Furring Strips - Commonly 1″ x 2″ or 1″ x 3″ and can be installed vertically or horizontally. Spacing will depend on the type of finishing or subfinish material. For a thin material, 12″ might be acceptable where 16″ or 18″ might be more suitable for a thicker more rigid material.


“Z” Metal Furring Channels -Z-furring is typically utilized with rigid foam insulation and is shaped like the letter Z. It is commonly spaced 16″ on center with gypsum board but may be spaced out as far as 24″ when thicker more rigid materials are installed against it. Z-Furring is commonly available in 1″, 1-1/2″, 2″, 2-1/2″ and 3″ depths. The most commonly stocked and sold length is 10′ but custom lengths can often be had upon request, 10 pieces to a bundle and 320 pieces to a pallet. There will typically be pre-drilled holes in the (3/4″ wide) outer flange and the (1-1/4″) inner flange for attchment to the existing wall and attachment of the wall material.

The type of fastener utilized will depend on the type of material the furring is being attached to, wood screws for wood, and power driven screws for masonry and concrete. Gauges (from light to heavy) can often be found as follows: 25, 22, 20, 18, 16, 14. Different variations of these thicknesses are available and galvanized furring can be had for exterior, moisture resistant applications.


Resilient channel is a style of metal furring which assists with dampening airborne sound transmission.Hat channel metal furring is used most commonly on ceilings and masonry walls for leveling and suspension of wall sheathing.

Hat channel furring is also very popular for hanging standalone ceiling tiles.


And also for hanging a drywall drop ceiling.
