CGI Windows & Doors

What CGI Windows & Doors does

CGI Windows & Doors designs and manufactures impact-resistant windows and doors for residential and light commercial applications, primarily in hurricane-prone coastal regions of the Southeast United States. Its product portfolio centers on the legacy Sentinel line (single hung, horizontal roller, fixed, casement, project-out, and designer fixed windows, plus sliding glass doors, French doors, and balcony breeze doors) and the transitioned Sparta by PGT and SCOUT by PGT aluminum lines. Supporting components include structural aluminum mullion systems (clipped and unclipped extruded aluminum tube configurations). All products are engineered for impact resistance and carry product-specific certifications including Miami-Dade County NOA, Florida Building Commission Product Approval, and Texas Department of Insurance approvals, which are required for sale in high-wind coastal jurisdictions.

The company operates as a subsidiary brand within the PGT Innovations portfolio under MITER Brands (legal entity: MI Windows and Doors, LLC, headquartered in Harrisburg, PA). It distributes exclusively through an authorized dealer network, with a dealer-locator and quote-request functionality on its website. End customers are homeowners needing impact-resistant fenestration for hurricane protection and rehabilitation, alongside architects, builders, and contractors who specify impact-certified products for new construction or replacement. The CGI website functions primarily as a marketing, lead-generation, and legacy customer support platform, referring inquiries to authorized retailers in the network.

Revenue is generated through hardware sales of impact-resistant fenestration products via the dealer channel. No direct pricing is publicly disclosed; transactions are negotiated through dealer quotes. Following integration into the PGT portfolio, the website has shifted to a legacy support posture, with warranty coverage cut off for purchases after 12/15/2025 and product pages directing customers to PGT-branded equivalents (Sparta by PGT, SCOUT by PGT). The company holds no app presence, no public API, and no disclosed AI, data, or software capabilities.
