CGI Impact Windows & Doors — South Florida Authorized Installer

Yes. CGI Windows & Doors was acquired by MITER Brands in the same 2022 rollup that brought in PGT and Milgard, and continues to manufacture under the CGI brand name. The Sentinel, Sparta, Targa, and Estate product lines are all currently active, all carry current Miami-Dade Notice of Acceptance, and the Hialeah/South Florida engineering footprint stayed with the brand post-acquisition. Lead times typically run 5-8 weeks for stock configurations.

Yes — CGI's South Florida-engineered impact glazing carries Miami-Dade NOA across the catalog, the heaviest aluminum extrusions in the market on the architectural-tier Sentinel line, and post-MITER acquisition the warranty + supply-chain infrastructure aligns with PGT WinGuard's. We install CGI for whole-home aluminum aesthetics (Sparta) and coastal/high-rise installations (Sentinel). The slim sightlines are the biggest competitive advantage vs PGT WinGuard Aluminum on equivalent openings.

CGI Sparta installation runs roughly $600–$1,400 per opening installed; CGI Sentinel and Targa run $800–$1,800 per opening depending on size, glass tier, and finish. A whole-home CGI Sparta install on a 2,000 sq ft single-family home typically lands between $25,000 and $40,000 with permit. CGI's premium lines cost ~20-30% more than equivalent PGT WinGuard configurations.

CGI and PGT are sister brands under MITER — both pass HVHZ code, both carry Miami-Dade NOA, both have South Florida manufacturing footprints. CGI Sparta typically wins on slim aluminum sightlines for whole-home replacements; PGT WinGuard typically wins on owner-occupied production-builder homes because of inspector + dealer familiarity. We install both and recommend per project.

Sparta is CGI's value-tier aluminum product — slim sightlines, 175 mph wind rating, value pricing for whole-home replacements. Sentinel is CGI's premium architectural-tier aluminum — heavier extrusions, custom finish options, oversized opening capability. Both pass Miami-Dade NOA; Sentinel typically costs 20-40% more than Sparta on equivalent openings.

Sparta also ships in a vinyl configuration for budget-constrained installs where the homeowner wants a CGI product but at a vinyl-frame price point. Same NOA + same wind rating; the trade-off is wider sightline and standard vinyl color palette (no architectural finishes).

Yes — CGI's original engineering and manufacturing footprint is South Florida-based (Hialeah). Post-MITER acquisition the manufacturing is integrated across the MITER plant network, but the CGI lines are still manufactured for the South Florida market with HVHZ-specific configurations.

All three carry Miami-Dade NOA and pass HVHZ code, but they're aimed at different segments. ES Windows (ESW) is the premium architectural-aluminum specialist — Elite + Prestige + Multimax for luxury custom builds. CGI is the slim-sightline aluminum line for whole-home + coastal installs. Eco Window Systems is the value-tier independent (non-MITER) brand with shorter lead times. SafeGuard installs all three: ESW for custom + oversized openings, CGI Sparta for whole-home aluminum aesthetics, Eco for value-conscious whole-home or hurricane-season tight-supply timing.
