Choosing a width is all about design. Smartplank offers 2 1/4", 3”, 4”, 5”, 6”, 7” and 8” standard widths. We offer wider widths by special quote. Design trends are clearly demanding wider widths, which may require additional installation practices such as glue assist. We are also seeing plenty of requests for mixed widths. Because of the quality, dimensional stability and technology of Smartplank engineered products, wider widths can be used in any interior application.
