Tongue & Groove Siding

T&G Wood Siding is a best seller because of its versatility. It can be used indoors or outdoors, rough side or smooth side, installed horizontally, vertically or diagonally, to provide distinctly different looks. Tongue & groove siding has both a rough and smooth face and is normally graded to the rough face (the best visible face) unless requested otherwise for a higher price.

Tongue & Groove Patterns (T&G) have the greatest variation in profile - the outline or shape of the board. How distinct or shadowed the line between the boards appears after installation depends on the shape of the edge. Most TNG patterns are "beveled" on the edges - called a V Edge (as in diagram below). The depth and angle of the beveling determines how distinct the edges appear.

A wider 1x8" pattern can be selected to have a V-Groove in the center of the board. This gives the illusion of a narrower board (1x4") when installed but with the time savings of a wider board (1x8"). Patterns without any V Edge are referred to as Flush-Joint (cedar, pine) or Butt-Joint (redwood). Center-Matched means the Tongue is positioned exactly in the middle of the thickness.

T&G is best milled when fully seasoned - Kiln Dried or Air Dried to the optimal moisture content. Select Tight Knotty grades are popular for their warm, rustic look. Tongue & groove siding is also milled in CLEAR grades, with NO or or very few knots, adding a more formal, streamlined appearance.

Tongue & Groove TRUE Measure


You might be wondering why our Buffalo diagrams above have 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 identification only. Even though a pattern is called 1x6" or 1x8" that does not mean it measures 1 inch thick and 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 T&G 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 tongue depth. An 8" NOMINAL T&G 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 tongue depth. This is called the pattern's "exposure" - the visible part of the board when installed on your wall.
 
The Western Wood Products Association (WWPA) and California Redwood Association (CRA) diagrams below are industry pattern standards and display actual numbers but they are guidelines not milling requirements. Over the years milled dimensions have shrunk (and continue to do so). Once you have calculated your project's SQUARE FOOT area you need to get the true dimensions - especially the exposure - of the wood siding boards you are buying.
 
Read our T&G coverage SQFT to LFT Coverage and "Buyer Beware" warning   to make sure you ask the right questions BEFORE you BUY.

END-MATCHED Tongue and Groove (below) is NOT a siding standard. It is a special option of interior paneling that makes installation easier when spanning wall studs or ceiling beams. The T&G Ends can be beveled as shown in the pictures or flush joint.

TONGUE & GROOVE - SQFT LFT Coverage


T&G patterns are 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 based on WWPA industry standards. HOWEVER individual mills often have their own pattern standards which vary from the norm (usually smaller). 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!
 

T&G Cedar Siding Coverage
Nominal WidthDressed WidthExposed FaceLinear Ft Factor*
6"5 1/2"5"2.4
8"7 1/8"6 3/4"1.78
10"9 1/8"8 3/4"1.37
* assuming 3/8" board overlap


1x6" Pattern Coverage Example: If you are siding four walls 8 feet high by 40 feet long with 6" wide Tongue & Groove boards and we allow 10% of the total square feet for openings, you would need approximately 3000-3100 linear feet:

SQFT AREA: 4 * 8 * 40 = 1280 SQ FT - 128 (10% openings) + 115 (10% trim/waste) = 1267 SQ FT

6" T&G Pattern: 1267 SQ FT * 2.4 linear factor = 3041 LFT
