Frequently Asked Questions
The CWS-812E is the vinyl impact single-hung window in Custom Window Systems' Hurricane Guard line, built for Florida residential installations. Single-hung means the bottom sash raises to ventilate while the upper sash stays fixed, the most common window style on Florida homes. We install the CWS-812E across South Florida and will help you decide whether the vinyl 812E or an aluminum-framed Hurricane Guard single-hung is the better fit for your home.
Yes, the CWS-812E is Large Missile Impact (LMI) rated and is HVHZ-approved for impact protection. It is documented under Florida Product Approval FL16177.R5 and related approvals FL17647 and FL5823. Because vinyl Hurricane Guard products carry Florida statewide approvals plus selected HVHZ certifications, we confirm the exact approval and zone coverage that applies to your opening before we permit the job.
The CWS-812E vinyl single-hung is rated to 70 psf positive and 70 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. Since the required design pressure depends on the opening's height and exposure, we verify the rating your specific window must meet at quote.
The CWS-812E uses a 7/8-inch overall insulated glass unit: an outer lite of annealed or tempered glass, a 7/16-inch airspace, and a laminated inner package built around a .090-inch PVB interlayer bonded between glass plies. That laminated layer is what holds the glass together under impact and also helps cut outside noise. We can review the glass makeup with you so you understand how the unit performs.
The CWS-812E is the vinyl-framed single-hung in Hurricane Guard, while CWS also offers aluminum single-hungs in the same line. Vinyl frames are a common choice for energy efficiency and low maintenance on Florida homes, and both substrates carry impact ratings. We'll compare the vinyl 812E against the aluminum options on your quote and recommend the right one for your budget and openings.
Installed pricing for the CWS-812E depends on the size of the window, the glass package, and the condition of the existing opening, so there is no flat price. As your installer, Armor Pro handles the measurement, permitting, and code-compliant installation, and we provide a free, no-obligation estimate. Contact us and we'll measure your openings and quote the CWS-812E for your project.
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.
