Headquartered in Northville, MI, OX Engineered Products is a leading specialty manufacturer of structural sheathing and thermal insulation building products. OX provides a variety of building materials serving both the residential and commercial construction markets throughout the United States. OX products are designed to allow builders to save time and money while meeting the most stringent building codes. OX creates truly innovative products that are built to perform inside and out. While others might rewrap, rebrand, or repackage ideas, we’re reimagining what building products can do. Constantly asking “Why?” Why can’t sheathing provide insulation in addition to strength? Why can’t being eco-friendly also be friendly to your bottom line? Why can’t you cut your installation time without cutting corners? Why can’t the best products be stably and competitively priced? We’re unafraid to ask questions. Because questions get us answers to the problems builders face every day. Better buildings and better building products go hand-in-hand. At OX, we believe that to the core.
