Western Red Cedar Siding & Trim

Experience the timeless beauty of real cedar siding & trim.  Cedar is the perfect partner for stone, slate, brick, and other natural building materials.  No other building material reflects such a true embodiment of the natural environment. 

Cedar is well recognized as a structural material with known mechanical and physical properties.  For structures such as large buildings in which the strength, stability and the appearance of exposed wood elements are of significant importance, cedar offers long term durability and performance.

Thermal and Insulating Properties
Western Red Cedar has good insulation value because of its low wood density and grainy texture. It is the best insulator among common available softwood species.

Durability

When treated right, cedar siding provides years of excellent performance with nominal effort. The choice of how to finish your Western Red Cedar siding is an important consideration.  You can leave it to weather to a natural patina, use a UV inhibitor to retain the natural beauty of the wood or choose to pre-finish to a color of choice.

Coverage of Western Red Cedar Siding

To obtain the coverage of a specified width of siding from Table below, perform the following calculations:

  1. Calculate total wall area (length x height).
  2. Subtract square footage of openings (windows, doors) to determine wall area for siding.
  3. Add 10% for trim.
  4. Multiply figure by the appropriate factor from the table for linear or board feet.

Example:

  • Length x height = 160 square feet
  • Door = 20 square feet    Window = 20 square feet   Area for siding = 120 square feet
  • Add 10% for trim = 120 + 12 = 132 square feet
  • Assuming 6 inch siding    132 x 2.67 = 357.4 linear feet    132 x 1.33 = 175.6 board feet

Notes:

  1. Assuming minimum 1″ overlaps. Larger overlaps can be used, particularly on wider sidings such as 10″ and 12″ pieces.
  2. Linear Feet Factor = Exposed Face Width/12.
    Board Feet Factor = Nominal Width/Exposed Face Width.
