What Ultrafab does

Ultrafab, Inc. is a private US manufacturer of pile and extruded weatherstripping products for the fenestration (window and door) industry, and of specialty brush and seal component parts for original equipment manufacturers (OEMs). Founded in 1970 and headquartered in Farmington, New York, the company operates as a subsidiary of Roto Window and Door Technology and has been an active contributor to industry standards-setting through the Fenestration and Glazing Industry Alliance (FGIA), including co-development of the 701 and 702 weatherseal standards. The product portfolio spans three core lines: (i) pile weatherseals under brands such as Tri-Fin, FIVE FIN, ULTRA FIN, ULTRA PILE, ULTRA PLUG, ULTRA REACH, ULTRA SOFT FIN, ULTRA TECT, ULTRA LOC, Gold Series, and Q Series in multiple backing variants; (ii) extruded seals including flexible and rigid PVC, multi-hollow bulb, polypropylene leaf, push-in, T-slot, ULTRA GLIDE, and ULTRA CELL micro-cellular foam variants; and (iii) specialty products such as custom brush seals, mounted brushes, roller brushes, AngleOn/AngleOn XT vibratory feeder brushes, ULTRA NYLON, ULTRA BEND, custom extrusions, and fire-rated (UL 94-V0) brushes.

Ultrafab's underlying technology centers on a proprietary non-woven manufacturing system that guarantees uniform pile height and backing widths, combined with ultrasonic welding assembly that integrates fins, fibers, and backing into a single unitized component resistant to separation during fabrication or use. Manufacturing is ISO 9001:2015 certified and operates from three US production sites (Farmington NY, the new Spartanburg SC facility inaugurated April 2026 with up to 50 machines on 24/5 schedules, and McPherson KS), plus warehouse locations in Dallas TX and Roberts WI. The company runs an AAMA-accredited test lab offering free air resistance and wind-driven rain testing to customers, and all weatherseals meet or exceed AAMA Class A requirements. Business model revenue is generated through direct B2B sales of manufactured components on a quote-based, pay-as-you-go basis to window and door fabricators and extruders (primary segment) and to OEM manufacturers across transportation, pneumatic tube, industrial lighting, office equipment/printer, and industrial automation verticals (secondary segments). Distribution is direct via a Request a Quote channel, regional sales representatives, and an interactive digital catalog, supplemented by trade show co-exhibition with parent Roto at GlassBuild America, WinDoor, Advanced Textiles Expo, and Automate. Pricing is not publicly disclosed; the company has announced 3.5% to 5% price increases effective January 2026 and a 4.7% temporary surcharge effective June 2026 across major product lines.
