As one piece, it removes the need to layer multiple wood boards or strips on site, and avoids the joints that open and crack as wood beams move. This profile can be custom modified to suit site needs. Its smooth plaster finish gives a monolithic look, on a lightweight EPS core that stays dimensionally stable and straight. Primed and painted after installation.
