Castlewood Oak in Tower by Shaw Floors. The Castlewood collection has an abundance of the natural charm that makes hardwood floors so desirable. Creating its stunning character are stylish 7 1/2" widths, extremely handsome linear graining, and sawn face veneers that closely resemble solid hardwood. Castlewood's colors are visually rich - with the beautiful knots, mineral streaks, and natural splits seen in heirloom woods. Heightening its appeal is a very low-gloss finish, which calls to mind vintage European oil-rubbed floors.
