Positioned as the residential storm-protection specialist — no shutters required, meets HVHZ and non-HVHZ impact codes |

| Installation | New construction and replacement; sold through PGT's tiered dealer network (Diamond / Platinum / Gold) concentrated in the Southeast, particularly Florida |
Notes
Vinyl, IMPACT-RESISTANT. Re-verified September 19, 2026. Major correction: PGT replaced its warranty effective September 1, 2026 — the record previously said non-transferable with no labor; the new document transfers (10-year terms for later owners) and includes 2 years of skilled labor inside PGT's 9-state service territory. Double hung added to the style list; product URL changed from /winguard to the WinGuard Vinyl page. The accidental glass-breakage add-on described earlier comes from older PGT documents and was not re-confirmed for 2026 — ask the dealer. Verify impact approvals (e.g. Florida product approval / HVHZ) for your exact location. Performance data is style- and glazing-specific — check the NFRC label
