What MFM Building Products Corp does

MFM Building Products Corp is a 65-year-old (founded 1961) US manufacturer of self-adhering waterproofing membranes and weather barrier products for the residential and commercial construction industries. Its core technology is cross-laminated polymer films laminated to rubberized asphalt adhesive systems, engineered for self-adhering installation and self-sealing around fasteners, with patented products including WindowWrap PSX-20 (US Patents 6,479,119 and 6,627,017) and the foundational Peel & Seal composition (introduced 1988). The product line spans roofing membranes (Peel & Seal), steep-slope underlayments (Ultra HT Wind & Water Seal, Premium HT Tile & Metal, StormStopper FSU, IB-3 StormStopper Plus), window and door flashing tapes (WindowWrap, SubSeal-40, SubSeal-60), construction and roof tapes, HVAC duct/pipe wrap (FlexClad), and, following the April 2025 merger with NAC Products, interior flooring crack isolation, sound control, and waterproofing products (NAC / MFM Flooring Division).

The business sells physical building products (hardware sales) at unit pricing through an extensive multi-channel distribution network: building product distributors, specialty building supply houses, and lumberyards nationwide, complemented by an own e-commerce storefront and a network of independent sales representative agencies covering US states and territories. MFM serves three primary end segments - commercial construction, residential construction, and metal/tile roofing contractors - and is differentiated by a dense stack of third-party certifications (UL Class A, ICC-ES ESRs, AAMA 711, ASTM E108/D1970, Miami-Dade County, Florida Building Code, Texas Department of Insurance, BAA/BABA compliance, and Fortified Building Program listing) that lock in specifiable status on public, commercial, and high-wind/wildfire-zone projects.

The company is headquartered and manufactures exclusively at a single campus in Coshocton, Ohio (525 Orange Street), which was expanded by approximately 50,000 square feet of production area, new offices, and an R&D laboratory completed in late 2022. MFM has been an Employee Stock Ownership Plan (ESOP) company since July 2017, is privately held with no institutional or venture capital ownership disclosed, and currently employs 101-250 people.
