Frequently Asked Questions
The CWS-999D is a vinyl impact casement in the CWS Hurricane Guard line that uses an alternate frame profile compared to the CWS-161E, giving it a different sash geometry for openings that call for it. Like other casements, it is side-hinged and cranks outward for ventilation with a tight seal when closed. We'll recommend the CWS-999D over the CWS-161E when your opening or configuration is better served by its different profile.
Yes. The CWS-999D is LMI (Large Missile Impact) rated for Florida installations and carries Florida Product Approval FL17388.R4. Because the vinyl Hurricane Guard line carries statewide approval plus selected HVHZ certifications, we'll confirm whether this model is approved for your specific Miami-Dade or Broward opening at the time of quote.
The CWS-999D is built with a laminated glass package using a .090-inch SentryGlas ionoplast interlayer between heat-strengthened lites, paired with a tempered inner lite and a 13/32-inch air space. SentryGlas ionoplast is a stiffer, stronger interlayer than standard PVB, which helps the laminated lite hold together under impact and pressure. This makes the CWS-999D a strong choice for demanding coastal openings.
The vinyl frame on the CWS-999D supports panel heights up to 80 inches and widths up to 37 inches, with a minimum size of about 17.875 by 20 inches. At the configuration level it is rated to a design pressure of +60/70 psf, and the product is structurally rated to +/-70 psf. We size each unit to your opening and confirm the final design pressure on your quote.
The CWS-999D casement carries a configuration design pressure of +60/70 psf and a product structural rating of +70/-70 psf, which is well suited to South Florida wind loads. The actual rating that governs your job depends on your opening size and location. Armor Pro confirms the required design pressure for your address and matches the window to it at quote.
Installed pricing for the CWS-999D depends on the size, the glass package, and the condition of your existing opening. Armor Pro is the installer, so we handle measurement, permitting, and installation, and we provide a free in-home estimate. Contact us and we'll measure your opening, confirm the impact rating and design pressure, and give you a firm installed price.
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.
