Double-Course Panel Siding

CertainTeed’s Double 7-inch 3G Straight Edge Perfection Shingles are composite wood and feature slanted, tapered gaps, a high-definition texture, and an offset corner to replicate a woven appearance. CertainTeed claims the double-course panel provides increased coverage and requires fewer fasteners than single-course siding. The shingles include hidden drainage holes, friction dots, reverse texture backing, and a built-in spacing indicator. Pricing starts at $450 per square. certainteed.com
