Plytanium Owns the Category
Plytanium is not just leading wood siding — it is the category. At 51.8% dollar share, it holds a position most building materials brands never reach. Three of the top five SKUs by dollar share belong to Plytanium, spanning plywood siding panels and ply-bead products at price points from $27.87 to $44.18. That breadth across formats and price tiers makes Plytanium difficult to displace through any single competitive move.
Share barely fluctuated over the period, moving from 51.4% to 51.3% to 51.8%. Stability at that level signals deep assortment entrenchment — a shelf position built into the planogram, not one riding a promotional cycle.
LP Lost Nearly Five Share Points in Three Months
LP entered September 2025 at 24.8% dollar share. By November, it sat at 20.0% — a 4.8-point decline in a single quarter. LP’s top SKU, a multi-use primed gray engineered panel at $39.82, holds 13.0% dollar share, but the brand’s trajectory is moving against it.
A nearly five-point drop in three months is not seasonal noise. LP’s decline opened space that other brands are ready to fill.
The Rest of the Shelf Is Moving
Ply-Bead held steady at roughly 13% dollar share, anchored by a plywood plybead panel at $27.74. Arauco grew from 6.9% to 7.8%, a quiet but consistent gain. Claymark hovered around 2%.
Plytanium dominates, LP is losing ground, and mid-tier brands are positioning to absorb whatever share LP surrenders. For manufacturers tracking this shelf, the brand-level trend matters more than the category average. Datavations tracks every SKU, every store, every sale across 11,936+ locations daily — the kind of census-level visibility that surfaces a 4.8-point share swing while there is still time to respond.
