Description

WindsorONE 1×8 Trim Board

Fascia takes more weather than any other trim on a building. It is the board rain runs off and gutters hang from. WindsorONE 1×8 measures 3/4″ thick by 7 1/4″ wide, and it is built for fascia, barge board, frieze and wide corner boards.

Rot, insect damage and mould are covered for 30 years. It is wood, finger jointed for stability, so none of the usual PVC compromises apply. You are buying it primed, which removes a full day from most trim schedules.

Choose between S4SSE for a clean painted finish and S1S2E when the elevation wants texture. Dimensions are the same either way.

You get 16ft and 20ft, which is what lets long runs go in without a joint.

Treat every saw cut as a new surface that needs primer.

3/4″ is the nominal industry thickness, and this hits it. Our 1×8 boards vary by species. Should this be the wrong width, WindsorONE 1×6 is the next size down and WindsorONE 1×10 the next size up. Sizes across the whole WindsorONE range are listed together for comparison.

This is the size where the 20ft length earns its keep, because a fascia run with no joint is a fascia run with nothing to fail.

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.
