Available in the three most popular profiles; Double 4" Woodgrain Clapboard, Double 4 1/2" Woodgrain Dutchlap, Double 5" Woodgrain Clapboard, this product has stood the test of time. It used to just be a brand of it's own Wolverine siding but has now been absorbed into Certainteeds lineup. While we cannot say the product is really bad there just isn't anything going on here to get us excited. At .042 it is the minimum thickness to put on a home you care about - classic styles DATED product. Good color selection still and a Certainteed warranty are it's only triumphs.
