This is an old-school profile typically seen on porch ceilings here in New England, although it can be used for a variety of applications. It makes a great wainscoting. Species: Douglas Fir. Douglas Fir is the major species produced in the West, with more volume shipped than any other species, and its sterling performance history is recognized the world over. It is abundant and widely available in second and third-growth stands yielding products in multiple grade classifications. Douglas Fir's light rosy color is set off by its remarkably straight and handsome grain pattern. Sapwood is white to pale yellow; heartwood is russet with high contrast between the springwood and summerwood.
