Is CGI Still Made? The 2026 CGI Windows Discontinuation Update

CGI Windows & Doors is a discontinued brand. Parent company MITER Brands ended manufacturing on October 31, 2025, after 33 years of production. MITER Brands was formed when MITER acquired PGT Industries in 2024. PGT Industries was CGI's prior parent company. The CGI discontinuation is a direct result of post-acquisition brand consolidation. If you are asking 'is CGI still made' — no. The factories are no longer producing CGI-branded units. No new CGI product approvals are being filed. The 3 core residential lines affected are CGI Sentinel, CGI Estate, and all CGI French door models. Each was sunset on the same October 31, 2025 cutoff date. Homeowners in markets like Miami and Fort Lauderdale relied on CGI as their preferred impact product. They now need to evaluate current alternatives. PGT WinGuard is the closest equivalent.

3 product lines were sunset on October 31, 2025: CGI Sentinel, CGI Estate, and CGI French door models. These represented the majority of CGI's residential volume in South Florida. Only 1 line survived the consolidation: the CGI Sparta series. It was rebranded as PGT Sparta and continues to be manufactured under the PGT umbrella. PGT Sparta carries forward the same core aluminum frame and impact-glass construction as the original Sparta. That made it popular in coastal markets. Homeowners in Boca Raton and West Palm Beach who specified Sparta can still source the product. It is sold under its new PGT name. Every other CGI SKU (stock keeping unit) is gone. If a contractor quotes you a CGI Sentinel in 2026, they are quoting from leftover inventory. That is not fresh production. That distinction matters for warranty and parts availability.

MITER Brands confirms it honors all existing CGI product warranties for installed units. Homeowners with CGI Sentinel or CGI Estate windows do not lose coverage because the brand was discontinued. Florida Building Code compliance is tied to the product's Miami-Dade NOA (Notice of Acceptance) or Florida Product Approval at the time of installation. The Florida Building Code governs all residential fenestration. It does not depend on whether the manufacturer is still in business. Those approvals remain valid for existing units. There is 1 important caveat: CGI replacement parts may become harder to source. MITER is winding down the brand's parts supply chain. If you have an active warranty claim — a failed seal, a damaged sash, or a hardware defect — file it now. Do not wait until 2027 when parts availability may be a lot worse. Homeowners in Pembroke Pines and Coral Springs with CGI installs should audit their windows this season. File any pending claims promptly.

PGT WinGuard is the closest current product to the discontinued CGI Sentinel. It offers the same laminated impact glass rated for High-Velocity Hurricane Zone wind loads. Both products target the same South Florida residential market. Both carry the Miami-Dade approvals required for new impact window installations. The deeper comparison covers frame profiles, glass packages, pricing tiers, and lead times. Read the full PGT vs CGI breakdown if you are replacing CGI units or pricing a new build. For a fast answer: WinGuard is the direct functional replacement. PGT Sparta (the surviving CGI Sparta line) is a second option. It suits buyers who want the Sparta frame profile. Both carry current product approvals and full parts support. Homeowners in Aventura and Doral who specified CGI on prior projects should check one more thing. Confirm whether homeowners insurance discounts apply to the replacement product — they typically do.

South Florida contractors moved fast once the CGI discontinuation was confirmed. PGT WinGuard had already been the dominant HVHZ product in markets like Hollywood and Miramar. That made the transition straightforward for most crews. SafeGuard's 20 full-time crews all answer to the same General Contractor. That structure keeps quality consistent across every project. No subcontracted installs source discontinued inventory from a broker. That matters now more than ever. Leftover CGI stock from distributors is still in the supply chain. A homeowner who accepts a discontinued-brand install in 2026 starts a parts-availability problem. Ask your installer whether the product they are quoting is actively manufactured. For the full decision framework, the PGT vs CGI comparison post is the reference to bookmark. It covers what to choose now that 'is CGI still made' has a definitive 'no' answer.
