Blakely Island Timber's Rustic Grade of t&g paneling is our most popular and economical grade of FSC® certified paneling. It is milled to the same tolerances as our flooring and select grades of lumber while displaying all the natural character of our island timber. In the lumber business, character simply means all naturally occurring knots, color variations and grain patterns that make wood enjoyable to look at. It is kiln dried to 8% to 10% moisture content and suitable for interior or covered exterior installation.
