Plank style construction is the lamination of wide planks of wood together to form the width of the countertop. Each board is the entire length of the countertop with the only glue joints running length wise. The individual boards range from 2 inch to 6 inch wide.
Upsides to plank style construction
It is considered the most decorative construction style because of its grain movement. Some people consider this almost a furniture style countertop, though it is very durable and holds up well in even harsh kitchens.
It is priced the best because it requires less work and less scrap than the other two styles.
Downsides to plank style construction
It is limited to 1 3/4 inch thick for many species, though some can go up to 2 1/4 inch thick.
Mineral oil can not be used on this style of countertop as it puffs the grain and makes the surface feel furry.
