WinDoor

What WinDoor does

WinDoor, founded in 2001 and headquartered in Nokomis, Florida, manufactures custom luxury aluminum-framed windows and doors with proprietary impact-resistant glass technology. The company operates as an affiliated brand under MITER Brands, a diversified building products conglomerate that also owns MI Windows and Doors and PGT Custom Windows and Doors. WinDoor's product portfolio centers on the flagship 8100 Aluminum Sliding Glass Door — featuring one of the largest certified impact-rated panels in the industry at 12 feet tall — and extends to bifold doors (BF1199A), pivot doors (PV9998A), thermally broken terrace doors (9050), French doors (FD9950A/9850A), garage doors (GD9995A), picture windows (9020), the GW9994G Envista bay window system, and the newly launched Triton Advanced Impact laminated glass. All products are manufactured to specification in the USA and carry AAMA, ASTM, Miami-Dade, and TDI certifications, with multiple Florida Product Approvals across the SKU range.

The company's core technology is its aluminum framing systems combined with laminated impact glass, including the proprietary Triton Advanced Impact glass which is positioned as nearly half the weight of competing impact glass while providing hurricane-force wind, intrusion, noise, and UV protection. Products serve three primary segments: high-rise condos and hotels (the "gold standard" luxury segment requiring highest impact ratings), custom luxury homes (where large-format sliding doors enable indoor-outdoor living), and bespoke custom applications.

WinDoer's go-to-market is exclusively indirect via an authorized dealer network, supplemented by a dedicated architect representative service that provides on-site specification support, CAD/BIM resources, LEED assessment, and AIA-accredited continuing education. Pricing is fully quote-based on custom specifications (size, color, finish, hardware, muntins, screens) and is not publicly disclosed. The company employs 251–500 people, sells exclusively across North America, and is privately held within the MITER Brands portfolio. In late 2025 WinDoor discontinued its Estate Product Line with service support transitioned to affiliated brand PGT through June 2026.
