D-Log Siding

Glue Laminated Timber Timber Cladding Cross laminated Timber Wood Molding Garden Wood Wooden House

D-Log Siding is a type of wood siding designed to give buildings the rustic charm of a traditional log cabin—without the complexity or cost of full-log construction. It's called "D-Log" because of its distinctive profile: one side is flat (for easy installation against a wall), and the other is rounded, mimicking the exterior of a full log.

Key Features of D-Log Siding
Profile Shape: Flat on the back, rounded on the front—like the letter "D".
Material: Typically made from kiln-dried pine or cedar.
Installation: Applied to standard frame construction using shiplap or tongue-and-groove joints.
Thickness: Often referred to as "quarter log" or "half log" depending on depth.
Lengths: Commonly available in 8', 10', 12', 14', and 16' boards.

Benefits
Rustic Aesthetic: Achieves the look of a log home without full-log walls.
Cost-Efficient: More affordable and easier to install than traditional logs.
Energy Efficient: Can offer better insulation when paired with modern framing.
Versatile: Suitable for both exterior and interior applications.

D-Log siding is a favorite among cabin builders and homeowners who want that cozy, woodsy vibe without the engineering challenges of full-log construction. If you're dreaming of a log-style retreat or want to add rustic flair to your home, this siding delivers the look with modern convenience.
