What Ox Engineered Products does
Ox Engineered Products is a U.S. specialty manufacturer of structural sheathing and thermal insulation building products, founded in 1970 with the ThermoPLY structural sheathing brand that has been marketed for over 50 years. The company is headquartered in Northville, Michigan, with manufacturing operations in Constantine, Michigan and Charleston, Illinois. Its product portfolio spans structural insulated sheathing (OX-IS, Strong-R), polyiso continuous insulation (ISO Red CI and ISO RED MAX variants with system effective R-values of R-6.1 to R-28), the ThermoPLY structural sheathing line, housewrap products (HomeGuard and Titan Drainage), and accessory categories including seam/flashing tapes, sealants, roof underlayment (ToughSkin), and surface protection (Ox Shield, Energy-Brace).
The company's core technical proposition centers on integrated 3-in-1 and 4-in-1 weatherization systems that combine structural sheathing, continuous insulation, weather barriers, and air barriers in single products, backed by 30-year limited system warranties. Products are designed to help builders meet increasingly stringent energy codes (IECC, ASHRAE 90.1) and enable R-20 wall assemblies with 2x4 framing rather than 2x6 construction, addressing labor shortages and reducing installation steps.
The company sells through a sales-led B2B model reaching residential builders, commercial contractors, architects, and distributors across the United States and Canada. Distribution is anchored by a broad network of lumberyards and building supply stores including Builders First Source, BMC, 84 Lumber, Carter Lumber, Boise Cascade, and ABC Supply, supplemented by an exclusive Canada distribution agreement with Goodfellow Inc. and dedicated direct sales representatives for enterprise accounts. Ox Engineered Products has been recognized as a National Preferred Partner by major home builders including David Weekley Homes (2020, 2021) and is positioned around a 10 million-panel D.R. Horton carbon-negative building materials partnership with Plantd. The company is currently a wholly-owned subsidiary of Amrize Building Envelope LLC, following Holcim's November 2024 acquisition and the June 2025 spin-off of Holcim's building envelope business into the newly independent, publicly traded Amrize. Ox Engineered Products itself is not independently publicly listed.
