Western Red Cedar trim boards are available in a variety of grades and textures to complement the style you have envisioned. Clear boards have a limited number of natural characteristics and are specified when “clean”, fine appearance of the highest quality is desired. They are available kiln dried or unseasoned. Knotty boards present a more rustic appearance and may be specified seasoned or unseasoned. Texture options of rough, surfaced one side, two edges and surfaced on four sides further enhance your design flexibility.

|Thickness (in.)||Width (in.)|
|Surfaced One Side Two Edges (S1S2E)|
|Surfaced Four Sides (S4S)|
Western Red Cedar boards may be specified in one of three surface finishes: rough; surfaced one side, two edges (S1S2E); or surfaced four sides (S4S).
The rough sawn texture from either circular or band saws is present on all four sides.
This versatile product is the most popular choice for trim boards. The surfacing process resulting in a rough sawn face and a smooth back provides uniform width and thickness tolerances. Typically graded from the rough face, it may in some instances be reversible to the smooth back.
The smooth surface on all four sides presents a uniformly sized product with a quality appearance. This surface finish is most commonly found on Clear grades.
