Frequently Asked Questions
The CWS-330 is the Fortify aluminum fixed picture window, designed to maximize daylight and view with no operating hardware. It's approved for up to five-story residential construction across the Florida Building Code, making it a good fit for large fixed openings, transoms, and view walls. We install it alongside operable Fortify windows so the elevation has a consistent aluminum look.
No, the CWS-330 is an aluminum non-impact fixed picture window, so it is not approved for the High Velocity Hurricane Zone (Miami-Dade and Broward) on its own. It is built for high design-pressure coastal performance without the cost of impact glazing. If your opening requires impact protection, we'll review the right approach during your free estimate.
The Fortify 330 fixed window is offered from 12 by 12 inches up to a maximum of 156 by 156 inches, with a design pressure rating of +40/-75 psf. That very large maximum size lets it serve as a true picture or view window. We confirm the exact size and the design pressure your opening needs before ordering.
The CWS-330 offers a wide glass selection including clear, bronze, gray, solar-control (SC) gray and bronze, GrayliteII, Solexia green, and Azuria blue in various thicknesses. SHGC ranges widely with tint, from about 0.81 on 1/8-inch clear down to roughly 0.34 on 1/4-inch GrayliteII, so darker solar-control tints reject more heat. We'll help you pick a tint that balances view, glare, and heat gain for your exposure.
The CWS-330 uses a non-thermally-broken aluminum frame, and across all glass options it carries a U-factor of 1.09 with a condensation resistance (CR) rating of 10. Because the heat transfer is driven by the aluminum frame and single-glaze options, you'd choose a solar-control tint to manage heat gain rather than relying on insulation. We'll explain the tradeoffs so you set the right expectations for an aluminum non-impact picture window.
Yes, the CWS-330 is documented under Miami-Dade NOA 24-0116.18 and NOA 25-0612.05, and a single approval covers both the flange (new-construction) and fin (replacement) frame configurations. Note these are design-pressure NOAs for a non-impact window, not impact (large-missile) approvals for the HVHZ. We provide the applicable NOA on your quote for permitting.
No. Fortify is aluminum non-impact, engineered for coastal addresses that need high design-pressure performance and corrosion resistance but where the code does not actually require impact glass. It is the step between Comfort Shield vinyl non-impact and the impact Hurricane Guard line. If your opening must carry impact glazing on its own, we'd move you to Hurricane Guard instead.
Only in a limited way. The 380 sliding glass door is HVHZ-eligible when it is paired with hurricane shutters, which satisfy the opening-protection requirement in place of impact glass. The Fortify windows are not HVHZ products. So in Miami-Dade or Broward, Fortify only works on a shuttered door application, and we confirm that path before specifying it.
CWS (Custom Window Systems) is a Florida manufacturer founded in 1986 and headquartered in Ocala, with additional plants in Miami, Medley, and Jacksonville totaling more than 700,000 square feet. Because the line is engineered and built in Florida around the state's hurricane code, the products are designed for our climate rather than adapted to it. We install and service CWS products throughout South Florida.
