Channel Rustic Lap Siding
WRC Channel Lap Siding Pattern milled PROFILE
WRC Channel Rustic Lap Stained & INSTALLED
Channel Rustic Siding has 1/2” overlap and a 1” to 1 1/4”
reveal that when installed creates a channel effect between siding boards. Channel Lap is often chosen for its rustic rough-hewn, textured appearance.
Channel siding installs with a minimal amount of effort and material wastage. The Channel pattern is traditionally installed horizontally with the edge of one board having a recessed area along its rear which
receives the shaped top-rear edge of the board next to or below it, so as to exclude water during rainfall.
Channel Lap Siding is normally supplied in partially seasoned (PAD) knotty grades with a rough saw textured face.
Commonly available sizes are 1x6", 1 x 8" and 1 x 10". Clear grades are milled and priced to order.

Lately we are seeing more channel lap vertical applications. This is a variant on the new "Shadaw Gap" narrow 1/4" shadow line profile that is popular now.
If you choose to install channel siding vertically be sure to bevel cut the ends and install so water is directed to the outside.

The Channel Rustic pattern provides excellent weather protection and allows for maximum dimensional wood change
(breathing) in climates of highly variable moisture levels between seasons - without adversely affecting the appearance of your
channel lap siding.
Installers usually leave an 1/8” air gap between boards to allow the wood to expand and contract with the

Channel Rustic Pattern Profile
There is only one standard Channel Rustic Lap pattern profile.
The overlap between boards (E) is usually 1/2" leaving approximately a 1" square channel (F) revealed between. The overlap and channel width can be custom modified - sometimes ;-)
Channel Lap Siding TRUE Measure
You might be wondering why our Buffalo diagram above has letters - A, B, C - instead of actual measurements. That is because siding measurements can vary from
mill to mill and lumber yard to lumber yard. Using letters allows us to confirm the TRUE dimensions with the mill before we sell to our customers.
NOMINAL SIZES are for industry identification only. Even though a pattern is called 1x6" or 1x8" that does not mean it measures 1 inch thick nor 6 or 8 inches wide.
Nominal 1x6, 1x8 refers to the size before the pattern profile is milled and NOT the board's final finished or "dressed" dimensions.

A 1" NOMINAL is usually 11/16ths inch thick. A 6" NOMINAL channel lap pattern is usually 5 3/8 - 5 1/2" wide including the overlap which results in 4 7/8 - 5 1/8 inches of exposed face depending on lap depth.
An 8" NOMINAL channel rustic lap pattern is usually 7 1/8 - 7 1/4" wide including the overlap which results in 6 5/8 - 6 7/8 inches of exposed face depending on the lap depth.
This is called the pattern's "exposure" - the visible part of the board when installed on your wall.

the right questions BEFORE you BUY.
CUSTOM MILLED 1x6 Channel Siding with 3/8" Shadow Gap between boards - NEAR CLEAR GRADE - Missouri
In the last few years a custom milled pattern has gained interest. The home in Missouri above built in 2011 was the first time we milled this pattern.
Sometimes called Shadow Gap, Shadow Line, Shadow Profile and Small Reveal
this is combination of the standard
Shiplap Siding "Flush Joint" and the Channel Lap patterns. The normal 1" Channel reveal is reduced to a fine narrow gap usually only 3/8 inch.
When installed a "shadow line" effect is created.

CHANNEL LAP SQFT LFT Coverage
Channel Lap siding is often sold by the linear (or lineal) foot. To figure out how many linear feet (LFT) you need you must multiply the square
foot area you plan to COVER by a linear factor based on the pattern width you have selected 6", 8", or 10".
The Lineal Foot Factor is derived by dividing 12 inches by the individual pattern's "exposed" face - the width that is
still visible after the siding boards are installed.
A) Calculate the square footage in walls: length x height = sq. ft.
B) Calculate, and then subtract, the square footage of openings
C) Add 10% to cover trim and waste = SQFT needed
D) Multiply SQFT result by the linear factor = LFT needed
BUYER BEWARE WARNING: The actual "dressed" widths and "Exposed Face" measurements below are suggested based on our
experience in the industry.
HOWEVER individual mills often have their own pattern standards
which vary from the norm. When you get ready to buy be sure to ASK for the exposed width to make sure you are
buying enough to complete the job!
CHANNEL RUSTIC LAP Siding Coverage Factors*
|Nominal Width||Dressed Width||Exposed Face||Linear Ft Factor|
|8" ||7 1/8" ||6 5/8" ||1.81|
|10" ||9 1/8" ||8 5/8" ||1.39|
* assuming 1/2" board overlap
Example of 1x8" Pattern Coverage estimation: If you are siding four walls 8 feet high by 40 feet long with 8" wide CHANNEL LAP
boards and you allow 10% of the total square feet for openings, you would need approximately 2300-2350 linear feet:
SQFT AREA: 4 * 8 * 40 = 1280 SQ FT - 128 (10% openings) + 115 (10% trim/waste) = 1267 SQ FT
8" Channel Rustic Pattern: 1267 SQ FT * 1.81 linear factor = 2293.3 LFT
