Our film veneers are laminated to an MDF flat panel, which provides a smooth and attractive recessed appearance. The 1/4” Flat Panels are shipped in 48” widths and precut to the perfect height (standard 23 5/8" if you need a 36" overall finished wainscot height). Cut the width in the field to suit your stile spacing and slide the 1/4” panels into the grooves provided in the stiles and rails.
