Description

WindsorONE 1×10 Trim Board

Once a board passes nine inches it stops being trim and starts being a surface. WindsorONE 1×10 measures 3/4″ thick by 9 1/4″ wide, and it is built for deep fascia, skirt boards, column wraps and porch ceilings.

Three coats, factory applied, and the edges are done as well as the faces. It is warranted against rot, insects and mould for three decades.

S4SSE and S1S2E are both carried. The second has one sawn face, useful when you want the texture to show through paint.

Both 16ft and 20ft are stocked, so most runs can be done in a single piece.

The warranty assumes cut ends were sealed, so seal them.

Where our 1×10 boards change thickness with the species, WindsorONE is 3/4″ throughout. For a different width, WindsorONE 1×8 is the next size down and WindsorONE 1×12 the next size up. For how this measures against every other board we stock, use the board size guide.

Wide boards move more across their width, so leave a little room at butt joints and prime the end grain.

WindsorONE is a premium line of trim boards, mouldings, and specialty millwork known for exceptional craftsmanship, architectural accuracy, and consistently smooth finishes. Every board is precision‑milled, primed, and built to deliver long‑lasting performance for interior and exterior applications. Contractors choose WindsorONE for its reliability, crisp profiles, and superior paint adhesion.
