Ox Engineered Products
The company traces roots to Thermo-Ply, a structural sheathing brand that has been on the market for over five decades. Ox Engineered Products now also owns the OX-IS, Strong-R, HomeGuard, and ToughSkin brands. The firm operates from a single address in suburban Detroit. Ox sells into both residential and commercial construction. Its product suite includes polyiso insulated sheathing for continuous insulation, Thermo-Ply as a lighter alternative to OSB, and tapes for sealing sheathing seams. The company offers a 30-year limited system warranty when using its tapes alongside other OX products. Geographically, the firm focuses on the US market, reaching builders and code officials via distributors and direct sales. The company does not publicly disclose ownership, number of employees, or financial performance. No named principals appear on the website. There are no recent operational events in public sources, no philanthropic vehicles, and no additional offices listed. Ox Engineered Products operates as a product manufacturer, not an investment vehicle. Its structural differentiator is a multi-brand strategy that ties sheathing, insulation, air barrier, and tape into one code-compliant system rather than selling standalone components.
