Frequently Asked Questions
No, the Comfort Shield single-hung is a vinyl non-impact window, so it carries a Florida Product Approval but not a Miami-Dade NOA and is not approved for the High Velocity Hurricane Zone (Miami-Dade and Broward). It is designed for inland Florida homes where the code does not require impact glazing. If you need impact protection in an HVHZ county, we'll point you to one of CWS's impact lines instead.
The Comfort Shield single-hung is documented under several Florida Product Approvals, including FL41975, FL41987, FL41990, FL42003, FL42007, and FL42009 (with their current revisions). The specific FL number that applies depends on the size and configuration you order. We confirm the exact approval on your quote and provide it to the building department for permitting.
The Comfort Shield single-hung is offered from 14.5 by 23.5 inches up to a maximum of 53.5 by 84 inches, with an AAMA Performance Class of R35 to LC50. That range covers most standard bedroom and living-area openings in Florida homes. We measure each opening and confirm the size and rating before ordering.
With dual-pane Low-E 270 insulating glass and argon, the Comfort Shield single-hung reaches a U-factor around 0.27, and triple-pane Low-E 270 with argon improves that to about 0.21. Beyond the standard Low-E 270, you can choose Low-E 366, bronze-tinted Low-E, obscure (privacy) Low-E, or tempered glass. We'll match the glass package to your comfort, privacy, and energy needs.
The Comfort Shield single-hung includes AutoLock automatic locking, a tamper-prevention interlocking checkrail, and steel hardware reinforcement with an anti-jar sill on the standard configuration. For child safety, you can add limited-opening hardware such as a Vent Stop and Window Opening Control Device (WOCD). We'll set up the security and safety options you want at quote.
The Comfort Shield single-hung comes in White (standard), Almond, and Fossil vinyl, with matching AutoLock hardware. For the look, you can add grilles-between-the-glass in Contour 3/4 inch or Flat 5/8 inch, plus patterns like 6-Lite or 9-Lite Prairie, Traditional, Starburst, Sunburst, Perimeter, and custom layouts. We'll show you the options so the windows match your home's style.
No. Comfort Shield is CWS's vinyl non-impact line, built for inland Florida residential and light-commercial projects where the building code does not require impact glazing. It does not carry a Miami-Dade NOA and is not for coastal HVHZ exposure. If your address needs impact glass, we'd move you to StormStrong for entry coastal impact or Hurricane Guard for HVHZ.
Comfort Shield is the broadest CWS non-impact line, with seven configurations: single-hung, double-hung, casement, awning, sliding window, picture window, and a sliding patio door. That range lets us handle most of an inland home from one line. To see how the styles look together on your elevation, you can use our Window and Door Designer and Visualizer.
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.
