Western Red Cedar Channel Siding

Western Red Cedar channel siding is a popular type of lap siding that provides excellent weather protection, especially in areas where the moisture levels change with the season. The profile of each piece of channel siding overlaps the next piece partially, thus creating a deep, recessed channel effect.

Channel siding is readily available in knotty grades with a rough sawn, textured face in the following dimensions

  • 1×6” unseasoned or kiln dried
  • 1×8” unseasoned or kiln dried
  • 1×10” unseasoned

*Please note-the dimension described is not the finished or “dressed” size after the channel is milled, but refers to the size of board that the piece of channel is used to create the pattern*

Other dimensions, as well as clear cedar grades, or other species of wood are available by special order. In this photo, we worked with a specialty mill to have a true 1″ thick channel siding pattern created out of knotty Western Red Cedar for a customer in North Carolina.

Channel siding can be installed horizontally, vertically or diagonally. Be sure to allow a 1/8” expansion gap between the pieces and do not nail through the overlaps. One nail through the face is sufficient for channel siding that is 6” or less.  For profiles over 6”, two nails should be installed through the face, keeping nails 2-1/2” to 3” apart to allow for movement without splitting.

When installing channel siding horizontally, start at the bottom and work up. For vertical or diagonal applications, the siding should be nailed to blocking or furring strips as needed to ensure that the nail penetrates solid wood.  Stainless steel, or other corrosion resistant, ring shank nails are recommended to hold the siding in place.
