Frequently Asked Questions
The CWS-380 No-Steel is the Fortify aluminum sliding glass door in an all-aluminum configuration with no steel reinforcement, making it a lighter assembly. It's intended for narrower openings where the added structural capacity of the reinforced variant isn't needed. We help you choose between the No-Steel, Standard, and Reinforced 380 versions based on your opening width and design-pressure requirements.
The CWS-380 No-Steel is a non-impact aluminum sliding door, but it is HVHZ-eligible when paired with hurricane protection shutters. That makes it an option in Wind-borne Debris Region counties where impact glass is optional but the coastal corrosion package is required, as long as approved shutters protect the opening. We'll confirm exactly what your address and the code require before quoting.
The CWS-380 No-Steel slider runs from 36 by 36 inches up to a maximum of 243.25 by 96 inches, with a design pressure rating of +40/-77 psf. Even as the lighter all-aluminum variant, it covers wide multi-panel patio openings. We measure your opening and confirm the size and design pressure your project needs before ordering.
The No-Steel 380 is an all-aluminum assembly without steel reinforcement, which keeps it lighter and suits narrower openings, while the Reinforced 380 adds steel for greater structural capacity on larger or higher-load openings. Both are part of the same Fortify aluminum non-impact line. Armor Pro recommends the right variant after reviewing your opening size and the design pressure your elevation requires.
Yes, the CWS-380 No-Steel is documented under Miami-Dade NOA 24-0116.21. Because it is a non-impact door, its HVHZ use depends on pairing it with approved hurricane shutters per that approval, rather than relying on impact glazing. We provide the NOA on your quote so the building department has it for permitting.
Installed price depends on the door size, the number of panels, and whether your opening needs shutters for HVHZ compliance, so we don't publish a flat rate. As the lighter all-aluminum non-impact variant, the 380 No-Steel is typically a more economical choice than the reinforced or impact options for suitable openings. Armor Pro provides a free, no-obligation estimate after we measure your opening.
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.
