Frequently Asked Questions
The CWS-957E is the only vinyl single-hung in the Hurricane Guard line that carries a Miami-Dade Notice of Acceptance, which is why we reach for it when a vinyl-framed single-hung needs to go into a High-Velocity Hurricane Zone opening. Other vinyl single-hungs in the line, like the 812E, run on Florida Product Approvals. We help you pick the right one based on whether your address falls inside HVHZ jurisdiction.
Yes. The CWS-957E is LMI impact-rated and carries Miami-Dade NOA 24-0116.06, the companion approval that clears it for HVHZ installations in Miami-Dade and Broward. It is also documented under Florida Product Approval FL17339.R5. We confirm the active approval on your permit so your vinyl single-hung is fully code-compliant for your county.
The CWS-957E vinyl single-hung is rated to 60 psf positive and 60 psf negative design pressure, with the single-hung configuration carrying a +50/-70 psf rating depending on size. It installs from about 13.5 by 21 inches up to roughly 52 by 96 inches. Because the design pressure your opening must meet depends on its height and wind exposure, we verify the required rating at quote.
The CWS-957E uses a 7/8-inch overall insulated glass unit: an outer annealed lite, a 1/2-inch airspace, and a laminated inner package built around a .090-inch PVB interlayer bonded between glass plies. The laminated interlayer is what keeps the glass intact under impact and also helps reduce outside noise. We can walk you through how this makeup performs against heat and sound for your home.
Both are options for HVHZ openings: the CWS-957E is the vinyl single-hung with a Miami-Dade NOA, while CWS also offers aluminum single-hungs in Hurricane Guard with their own Miami-Dade approvals. Vinyl frames are often chosen for energy efficiency and low maintenance, while aluminum reaches higher design pressures. We'll compare both on your quote and recommend the right substrate for your openings and budget.
Installed pricing for the CWS-957E depends on the window size, the glass package, and the condition of your existing opening, so there is no single price. As your installer, Armor Pro handles measurement, HVHZ permitting, and the code-compliant installation, and we provide a free, no-obligation estimate. Get in touch and we'll measure your openings and quote the CWS-957E for your home.
The aluminum Hurricane Guard products carry current Miami-Dade NOAs and are HVHZ-eligible end to end, covering single-hung, slider, picture, casement, hinged patio door, and sliding glass door. The vinyl Hurricane Guard products carry Florida statewide approvals with more limited HVHZ coverage. For a Miami-Dade or Broward project we generally spec the aluminum side, and we confirm the exact approval against your opening size before ordering.
Hurricane Guard is unusual in offering both substrates under one name. Aluminum carries the higher design pressures and the full HVHZ approval set, so it's the choice where the span, the pressure, or the HVHZ code demands it. Vinyl runs cooler thermally and lands at a lower price, which suits non-HVHZ openings where budget and energy lead. We can mix both within one house, choosing per opening.
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.
