Siding Patterns

Tongue & Groove T&G 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. The board edges are usually "beveled" but other styles that include flush-jointed, reveal and radius joints are also available. T&G siding has both a rough and smooth face and is graded to the rough face.

Shiplap siding
Shiplap Siding is a type of Drop Lap siding with tight joints similar to tongue and groove, but it laps over (11/16" depth of rabbet) With lap siding, the profile of each board partially overlaps that of the board next to it. In vertical applications, bevel cut the ends and install the lap siding so water is directed to the outside.

Bevel siding Bevel siding is lumber resawn at an angle to produce two pieces thicker on one edge than the other with a thick butt and a thin upper edge lapped to shed water. This pattern is special mill cut that allows the siding panels to fit together in such a way as to protect joints from water infiltration. It installs easily and gives an attractive shadow line.

Channel Lap - Rustic
Channel Rustic Siding has 1/2” overlap and a 1” to 1 1/4" reveal that creates a channel effect between boards. Channel Siding allows maximum dimensional wood change (breathing) in climates of highly variable moisture levels between seasons - without adversely affecting the appearance. Usually available smooth, rough or saw textured.

Dutch Lap Siding Cove lap siding is also know as Dutch Lap and German Lap Siding. Lap sidings were among the earliest types of finish siding. With lap siding, the profile of each board partially overlaps that of the board next to it. In vertical applications, bevel cut the ends and install the lap siding so water is directed to the outside.

Log Cabin Siding Log Cabin siding allows you to integrate the rustic charm of a log home with conventional frame construction. It looks exactly like a log but requires 75% less wood. The overlap ensures tight insulation against weather and eliminates the need for chinking between logs. The "reveal" pattern creates an attractive recessed effect between logs.

Siding/Paneling Coverage

Wood paneling is sold by the linear (or lineal) foot. Your quantity requirements are calculated by multiplying your square foot area by a linear factor based on the siding width. The Lineal Foot Factor is derived by dividing 12 inches by the individual pattern's exposed face.

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
D) Multiply the result by the factor for lineal feet

Coverage Example: If you are siding four walls 8 feet high by 40 feet long with 8" wide siding and we allow 10% of the total square feet for openings, you would need approximately 2250-2450 linear feet depending on pattern selected:

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

T&G: 1267 SQ FT * 1.78 linear factor = 2255.3 LFT

SHIPLAP: 1267 SQ FT * 1.78 linear factor = 2255.3 LFT

THIN BEVEL: not available in 1x8"

THICK BEVEL: 1267 SQ FT * 1.92 linear factor = 2432.6 LFT

DOLLY VARDEN: 1267 SQ FT * 1.77 linear factor = 2242.6 LFT

CHANNEL RUSTIC: 1267 SQ FT * 1.81 linear factor = 2293.3 LFT

DUTCH LAP: 1267 SQ FT * 1.77 linear factor = 2242.6 LFT

QTR LOG: 1267 SQ FT * 1.81 linear factor = 2293.3 LFT

Factory Finish

Factory finishing is a process that ensures a lasting, higher quality job than traditional "on site" stain applications. Most trim and sidings are installed before being primed which leaves the back unprotected and unsealed. When you use factory primed trim and sidings you protect your wood from moisture and the problems that result. All sides, edges and ends of the board are coated ensuring maximum protection of the wood fiber and stabilizing the moisture content of the wood.

Pre-primed wood saves time and labor costs. Up to 80% of the cost of painting is in labor. Eliminating this step reduces overall labor costs while assuring complete coverage on all sides of your sidings and trim. Pre-priming your siding eliminates the problems of lap marks, shrink lines, streaking, color variation, and dirt pick-up. Coating adhesion is improved compared to siding that is permitted to weather while waiting to be finished. Pre-finishing virtually eliminates weather related delays and lost production time. Why Acrylic Latex? Extensive exposure studies have confirmed that acrylic latex coatings are more durable then oil-based counterparts. When acrylic latex dries, it forms a flexible film that expands and contracts, unlike oil-based products that crack and become chalky.

Factory pre-staining ensures a lasting, higher quality job than traditional "on site" stain applications. With factory pre-staining, controlled temperature and humidity levels stabilize any moisture in the wood. All six sides of the board, including the butt-ends, are completely encapsulated, ensuring total protection. Coatings are applied with pressure rollers to spread the coating evenly for uniform coverage. The product is brushed deep into the surface for maximum protection and racked to air-dry prior to leaving the factory. The finished siding or interior paneling arrives at the job site totally protected from exposure to water and sunlight. Products Association and the California Redwood Association recommend pre-finishing.

Research from the U.S. Forest Products Lab indicates that untreated wood siding, even cedar siding, left to weather for just 30 days will experience a significant decrease in adhesion of film-forming finishes due to ultra violet exposure.

Est .10/LF for factory priming on 1x material, add .20/LF for factory priming on 2x
Est .25/LF for factory pre-staining on 1x material, add .35/LF for factory pre-staining on 2x
