In the fabrication of our custom laminate tops, which includes the square, bevel and wood edges we use ¾” particle board for the substrate and the banding giving you a 1 ½” thick top. To help against warping we put a backer sheet on the bottom side of the countertop. The post formed laminate tops, which include the full-wrap ogee, contemporary ogee, modern drop ogee, double radius, bullnose, waterfall and no-drip edges, use ¾” particle board for the substrate and 5/8” particle board for the banding giving you a 1 3/8” thick top. These tops also have the backer sheet on the bottom side of the countertop. Our most popular laminate colors come from Formica, Wilsonart, Nevamar and Pionite. Color samples are available at our office or you could visit the individual manufacturer’s website.
