Frequently Asked Questions
The CWS-7100 is Custom Window Systems' flagship aluminum impact single-hung in the Hurricane Guard line, and single-hung is the most common window operation on Florida homes. The bottom sash slides up to ventilate while the top sash stays fixed, which makes it a versatile fit for bedrooms, living areas, and most standard openings. We install the CWS-7100 throughout South Florida and will help you confirm it suits each opening at quote.
Yes. The CWS-7100 carries Large Missile Impact (LMI) certification and is HVHZ-approved, so it can be installed in Miami-Dade and Broward openings. It is backed by Miami-Dade Notices of Acceptance including NOA 24-0116.05 and NOA 25-0929.03, along with Florida Product Approval FL46524. We confirm the exact approval that applies to your size and configuration when we pull the permit.
The CWS-7100 single-hung configuration installs from about 13.5 by 21 inches up to roughly 52 by 96 inches. The line is rated to 67.5 psf positive and 100 psf negative design pressure, with the single-hung configuration carrying a +50/-70 psf rating depending on size. Because design pressure varies with the opening, we verify the rating your specific window must meet at the quote stage.
The CWS-7100 is available with a Low-E 270 insulating dual-pane laminated glass package using a PVB interlayer and argon fill, rated at a U-factor of 0.60 and an SHGC of 0.16. The laminated impact makeup uses heat-strengthened glass bonded to a 0.090-inch plastic interlayer, which is what gives it both storm protection and noise reduction. We'll walk you through the glass options that best balance heat gain and clarity for your home.
The CWS-7100 is an aluminum-framed window in the Hurricane Guard line and uses AutoLock hardware that secures the sash automatically when it closes. It also ships with factory pre-drilled fastener locations, which supports a clean, consistent installation. We can confirm the available finish options for your project when we measure and quote.
Installed pricing for the CWS-7100 depends on the size of the opening, the glass package you choose, and the condition of the existing opening, so there is no single sticker price. As your installer, Armor Pro handles measurement, permitting, and the HVHZ-approved installation, and we provide a free, no-obligation estimate. Reach out and we'll measure your openings and quote the CWS-7100 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.
