Frequently Asked Questions
The HR4110A is PGT's Sparta value-tier aluminum impact horizontal roller on a nominal 2-inch frame, where the sash slides side to side instead of up and down. It's offered in 2-panel and 3-panel layouts, including XOX configurations split a quarter-half-quarter or in even thirds, which makes it a good fit for wide openings. We install it in South Florida HVHZ projects that need a budget-friendly impact window for a wide span.
Yes, the HR4110A is LMI impact-rated and HVHZ-approved, so it's built with impact-resistant glass and qualifies for Miami-Dade and Broward openings that require impact protection. That lets you cover a wide opening with a sliding window while still meeting hurricane code. We'll confirm the current approval that applies to your configuration and opening at quote.
In its 3-panel XOX configurations the HR4110A reaches up to 111 inches wide by 63 inches tall, while the 2-panel XO/OX layout maxes out around 74 by 63 inches; all configurations carry a design pressure of +55/-65 psf. That makes the 3-panel a strong option for wide living-room or master-bedroom openings. We'll size the window and confirm the design pressure for your opening when we quote.
The HR4110A uses PGT's Energy Shield Max impact glass on a 5/16-inch PVB interlayer, with a U-factor of 1.12 and an SHGC of 0.26 to 0.29 depending on whether grids are added. The laminated impact glass also helps reduce outside noise on a wide window. For South Florida sun, the lower-SHGC option keeps heat gain down, and we'll review the choices at quote.
The HR4110A rides on adjustable brass rollers and is assembled with stainless-steel screws on a 1/2-inch flange frame, which keeps the sliding action smooth and the unit corrosion-resistant in coastal air. It comes in White and Bronze finishes with a 1-inch flat grid option. We coordinate the finish and grid with the rest of your Sparta windows so the home looks consistent.
There's no flat price, because the installed cost depends on whether you choose a 2-panel or 3-panel layout, the overall size, the glass package and grid, the finish, and the condition of the opening. Wider 3-panel units and larger spans cost more than a small 2-panel roller. Armor Pro gives a free, no-obligation estimate; we'll measure the opening and price the HR4110A for your project.
Yes. Sparta is PGT's value-tier aluminum impact line, large-missile impact-rated and eligible for the High-Velocity Hurricane Zone in Miami-Dade and Broward. The glass is the same laminated impact glass the premium lines use, and the approvals are real — the line simply trims the premium sizes, finishes, and high-pressure configurations to hit a lower price. The exact rating depends on the opening, which we confirm on the quote.
What you give up with Sparta is range, not code compliance. Sparta covers the core operation styles — single hung, horizontal roller, picture, architectural shapes, and a sliding glass door — in white and bronze only, with block-and-tackle balance hardware and a narrower set of sizes and design pressures. WinGuard Aluminum adds more colors, larger sizes, higher pressures, and a broader catalog including casements, awnings, and French doors. We reach for Sparta when impact compliance is required but the budget is the binding constraint.
PGT has built impact windows and doors in Venice, Florida since 1980 and is the largest impact-window and -door manufacturer in the country. It was the first company to develop impact-resistant products that met Miami-Dade County's hurricane code after Hurricane Andrew, and the line is engineered specifically for Florida conditions. PGT is now part of the MITER Brands family, alongside WinDoor, ECO, and NewSouth, but the products are still made in Florida under the PGT name.
