Eastern White Pine from the Connecticut River Valley is our best-selling species and the foundation of Timberline Lumber's business. Milled to our specifications by our mill partners, our EWP is kiln-dried to 8–10% moisture content and precision-machined to tight tolerances that ensure clean, gap-free installations on walls, ceilings, and accent features.
Why CT River Valley Pine?
Not all White Pine is created equal. Pine from the Connecticut River Valley region is prized for its tight, consistent grain pattern, warm honey-amber color, and clean milling characteristics. The cool New England growing climate produces slower growth rings and denser wood compared to plantation-grown pine from other regions. The result is a board that machines cleanly, finishes beautifully, and has the structural integrity to stay flat and true over decades of service.
Available Profiles
- V-Joint Tongue & Groove: The classic paneling profile. Small V-shaped channel at each joint creates clean shadow lines. Available in 1x6 (5.0" face) and 1x8 (6.75" face).
- Nickel Gap Tongue & Groove: Modern reveal profile with a crisp 1/16" gap between boards. Increasingly popular for contemporary farmhouse and coastal interiors. Available in 1x6 and 1x8.
- Beaded Tongue & Groove: Traditional beadboard profile with a rounded bead detail along one edge. Perfect for wainscoting, bathroom ceilings, and period-appropriate renovations.
- S1S2E (Surfaced 1 Side, 2 Edges): Surfaced smooth on one face with clean edges, rough on the back. The primary material for authentic exterior Board & Batten and Reverse Board & Batten siding. The rough-sawn back face holds stains and paints significantly better than a smooth planed surface, extending finish lifespan. Estimating ratio: one 1x12 board requires exactly one 1x4 batten (1:1).
- Rougher Head: Run through a rougher head to produce a slightly textured, rustic surface. Hides imperfections and gives a hand-planed look without the labor cost.
- Band Sawn: Sawn on a bandsaw for a distinctive rustic texture with visible saw marks. Popular for cabin interiors, timber-frame accents, and mountain-style homes.
- Shiplap: Overlapping rabbeted joint profile. Clean, modern look that's been a design favorite for the past decade. Available in 1x6 and 1x8.
- Channel Siding: Exterior siding profile with a deep channel at the overlap. Provides a pronounced shadow line and excellent weather shedding. 1x8 and 1x10. Important: Due to the rabbeted overlap, the exposed face width is approximately 5.0"–6.25" for a 1x8 (not the 7.25" nominal width). Always calculate square footage using the exposed face width to avoid under-ordering material.

Grades (NELMA Standards)
- Premium Grade: Highly refined appearance admitting only sound, tight knots (limited to 2" red knots or 5/8" black knots). Tight grain, uniform color. The premier choice for natural clear-coats and high-end painted surfaces where structural uniformity is paramount. Ideal for formal living rooms, master suites, and architectural millwork.
- Standard Grade: The traditional knotty pine. Sound and unsound knots of varying quality and size, along with minor acceptable checks, shake, and occasional heavy pitch. Our most popular grade — it provides the authentic, warm character that most customers envision when they think of pine paneling. Set expectations accordingly: natural rustic characteristics are inherent to this grade.
- Industrial Grade: The lowest common board grade. Admits large characteristics, pitch pockets, and potential skip dressing. Suitable only for highly rustic applications, rough construction, or scenarios where structural appearance is entirely secondary to cost savings — garages, workshops, and utility buildings.
Applications
- Ceiling paneling (V-Joint, Nickel Gap, and Beaded are all ceiling favorites)
- Wall paneling & accent walls
- Wainscoting & chair rail sections
- Porch ceilings (interior to covered porches)
- Exterior channel siding & gable accents
- Trim boards & base/crown molding
- Cabin & mountain home interiors
Flooring Warning: Eastern White Pine is a premier, highly workable species for paneling, ceilings, and wainscoting, but its inherent cellular softness (Janka 380 lbf) makes it entirely unsuitable for primary flooring applications. White Pine will dent and degrade rapidly under standard residential foot traffic. For traditional, durable softwood flooring, we strictly recommend our Heart-Pine-Character Southern Yellow Pine (Janka 870 lbf).
Finishing Recommendations
Eastern White Pine accepts stain, paint, and clear finishes beautifully. For a natural look, apply a clear matte polyurethane or water-based lacquer to lock in the warm amber tone. For painted applications, prime all six sides before installation — White Pine's low resin content means it holds paint exceptionally well with minimal bleed-through. If you want the wood to darken naturally over time, leave it unfinished; EWP develops a rich, warm patina with age.
