Eastern White Pine

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.

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.
