18″ #4 Undercourse Cedar Kiln Dried Sidewall Shingle 1 Square Carton, Natural

Description

Product Overview

These 18″ #4 Undercourse Cedar Kiln Dried Sidewall Shingles from Miller Shingle are engineered for sidewall applications in double-coursed installations and starter shingle roles. Made from premium Western Red Cedar, they offer natural color variation and consistent grain patterns that enhance architectural appeal. Each carton covers 100 square feet at a 14-inch exposure or 50 square feet at 7 inches — ideal for precise project planning. The kiln-dried process ensures dimensional stability and resistance to warping, making them suitable for both indoor and outdoor use in dry climates. Manufactured in the U.S.A., these shingles are designed for durability without compromising on aesthetic quality.

Usage

These shingles are specifically intended for undercourse sidewall applications, not roofing or starter-course installations. Ideal for residential and commercial projects where natural cedar siding is desired — such as porches, gables, or accent walls. They work best with traditional framing methods and can be installed on vertical surfaces using standard nails or screws. Perfect for DIY enthusiasts and professional contractors alike who value consistent color, grain integrity, and long-term performance in moderate climates.
