Impact protection, built for South Florida
The CWS-7900 is the flagship sliding glass door in Hurricane Guard, the aluminum impact slider Armor Pro installs on the wide patio openings of a CWS project. It runs up to four panels in XO, OX, OXO, OXXO, and XOOX, with stainless-steel rollers and anti-lift blocks that keep the panels seated and gliding under coastal wind loading. It is LMI impact-rated for the HVHZ, so a big lanai opening clears Miami-Dade and Broward on the door alone.
Armor Pro specs the CWS-7900 when a project wants a Florida-built aluminum impact slider with a current Miami-Dade NOA at a competitive price. Because CWS builds it in-state, the approvals and lead times stay close to home. For a smaller or budget opening, the vinyl Hurricane Guard slider covers it; the 7900 is the aluminum workhorse for the wide patio wall.

Frequently Asked Questions
Yes. The CWS-7900 is the flagship aluminum impact sliding glass door in the Hurricane Guard line and is Large Missile Impact (LMI) rated for the High Velocity Hurricane Zone, so a wide patio opening clears Miami-Dade and Broward on the door alone. It carries Miami-Dade NOA 24-0116.13 along with Florida Product Approval FL46529. We confirm the current approval that applies to your opening at the time of quote.
The CWS-7900 supports up to four panels in XO, OX, OXO, OXXO, and XOOX configurations, and reaches a maximum overall size of about 191.25 by 96 inches (with a minimum near 24 by 36 inches). That makes it the aluminum workhorse for a wide patio wall or lanai opening. We measure the opening and recommend the panel layout that gives you the best traffic flow and view.
The CWS-7900 uses stainless-steel rollers and anti-lift blocks that keep the panels seated and gliding under coastal wind loading, so the door stays secure and operable in high winds. It is rated to a design pressure of +90/-40 psf. We verify the design pressure your specific opening and exposure require before installing.
The CWS-7900 uses an insulated dual-pane laminated (PVB) impact glass package that reaches a U-factor of 0.66 and an SHGC of 0.14, so it blocks a large share of solar heat gain, which matters on a wide, sun-exposed patio wall in South Florida. The laminated PVB interlayer is also what gives the glass its impact resistance. We can review the glass performance with you when we spec the door.
The CWS-7900 is the aluminum impact slider Armor Pro specs for wide patio openings that want a Florida-built door with a current Miami-Dade NOA at a competitive price; because CWS builds it in-state, approvals and lead times stay close to home. For a smaller or more budget-conscious opening, the vinyl Hurricane Guard slider covers it instead. We will help you weigh size, budget, and finish to pick the right one for your project.
Installed price depends on the overall size, the number of panels (a two-panel XO costs less than a four-panel OXXO or XOOX), the glass package, and the condition of the existing opening, so there is no flat price for the CWS-7900. Wide multi-panel doors use more glass and hardware, which raises the cost. Armor Pro provides a free, no-obligation estimate once we measure your opening.
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.
