Old Mill® Shingle Lap

The Rich Appearance of Split Shingle Siding Without the Cost

Architectural charm and the rich appearance of split shingle without the cost? It’s Tru.

Less expensive and more durable than cedar, our TruWood® Old Mill® Shingle Lap Siding offers architectural accents without the typical number of culls or odd lengths. The staggered edge line of split shingle provides a warm, natural appearance that resists whatever Mother Nature throws at it. With shiplap edges that are easier to install, even your labor costs are lower. Truly amazing.
