Fortifiber Corporation

What Fortifiber Corporation does

Fortifiber Corporation, operating legally as Fortifiber Building Systems Group Inc., is a Nevada-incorporated manufacturer and supplier of flooring protection and moisture management products established in 1939 and headquartered in Fernley, Nevada, with 501-1000 employees. The company specializes in vapor retarders, moisture barriers, acoustic underlayments, and surface protection materials designed to protect wood, laminate, engineered flooring, and tile/stone installations from moisture vapor migration, sound transmission, and construction damage. Core product technology relies on asphalt-saturated kraft paper, polyolefin films, and polymer-modified membranes engineered to meet specific perm ratings and National Wood Flooring Association guidelines.

The product portfolio encompasses vapor retarders (Aquabar B, HWD-15, Moistop Ultra for Floors, FortiFlash 40 for Floors), acoustic underlayments (Accord Flooring Pad, Accord LVT Premium Underlayment with IIC 71/STC 67 ratings), and surface protection materials (FortiBoard, FortiBoard Tape, Utility Paper, Red Rosin), supported by complementary products like Scribe Rite pattern papers. Fortifiber operates as a B2B hardware sales business, distributing exclusively through professional building materials channels rather than direct sales, with select products like HWD-15 restricted to a select group of hardwood flooring professionals. Revenue mechanics are transactional and project-based, with pricing determined by product type, quantity, and channel relationships rather than disclosed standardized pricing.

Fortifiber is a wholly-owned subsidiary of Carlisle Companies Incorporated (NYSE: CSL), a Fortune 500 diversified conglomerate, operating under Henry Company's Building Envelope Systems portfolio. This corporate structure provides access to Carlisle's global distribution infrastructure and enterprise customer relationships. The company holds registered trademarks for nearly all major products, maintains ISO/IEC 17020 quality assurance monitoring, and several products carry CA 01350 indoor air quality certification and LEED point contributions, positioning Fortifiber as a specification-grade supplier in architect and contractor procurement workflows.
