When you are looking for an air of rusticity for the interiors of a home or any other space, you will not go wrong if you use the siding from aged and well-weathered barns.
Barn lumber is a board that has been weathered because of its long exposure to the elements, and this must be for at least a couple of decades; the longer the better. This antique wood will vary in color and will be deeply furrowed and these furrows allow the board to get a better surface contrast when used in an interior.
Most barn board lumber will be of a species that was part of the original trees that grew in the farmer’s fields and is more than often a softwood. Their surfaces are naturally textured by the weathering they have gone through and thicknesses may rarely be uniform. You must take this factor into consideration when you are using this lumber to form any part of your furniture or interiors.
