GlossaryPine Knotty
Veneer Specification
Description
White Pine is a softwood typically stemming from a wide range of species. It has many commercial uses. As a result, there is a great variation in color and natural characteristics based upon where the tree is sourced. Veneer stems mostly from sapwood. The color of Pine sapwood can range from off-white to creamy yellow to light tan. Heartwood colors can range from pale orange to reddish brown. The transition from sapwood to heartwood is visually distinct. Pine when plain sliced will produce straight and cathedral appearing grain patterns. Rotary sliced veneer will exhibit more bold and irregular grain patterns. The grain is moderately diffused. Grain color will be darker than the veneer flitch and can range from pale reddish orange to light brown. Pine is not as dense as Douglas Fir but still exhibits a moderately fine surface texture. Most natural characteristics found within the species are allowed. Pine will darken to a golden yellow color with exposure to light.
Woodport Grade
Rustic. Uniformity Density = 4.0/Square Foot.
Veneer shall be sourced mainly from the sapwood of White Eastern Pine. A wide variation in sapwood flitch color shall be allowed. Heartwood flitch to a pale orange color may also be utilized. Grain colors shall be moderately diffused, pale reddish orange to light brown in color. Solid dark brown or black grain colors are allowed in moderation but, shall not be conspicuous or detract from the overall finished appearance. Grain should be vertically oriented, straight to cathedral patterned. Irregular and circular grain patterns stemming from figures, burls and knots are allowed. Rotary appearing grain patterns will be allowed in moderation. Components manufactured from multiple veneer flitches shall closely match in color and grain pattern. Minimize splicing or trimming veneer through figures, burls and knots. Veneer shall not contain any blue, dark brown or black colored stains. Most natural characteristics are considered desirable in this grade with very little limitation with regards to occurrence or color. All natural characteristics shall be structurally sound. All voids and cracks shall be filled and sanded, as specified. All natural characteristics shall appear random, not patterned across the surface of the finished component. NOTE: Knotty Pine door panels are manufactured from solid wood, not veneered, and not included in this specification.
