Frequently Asked Questions
The SGD5570NS is the narrow-interlock variant of PGT's WinGuard Vinyl SGD5570 slider, using 2.5-inch panel interlocks to widen the glass-to-frame ratio for a more open, less obstructed view. It's a 2024 DWM Readers Choice Award winner. We install it on impact patio openings where you want the maximum unbroken view through a vinyl door.
The SGD5570NS uses slimmer 2.5-inch panel interlocks, so more of the opening is glass and less is frame, giving a cleaner sightline. The trade-off is a lower design pressure: the Preferred View is rated +60/-70 psf, while the standard SGD5570 carries +100/-100 psf. We'll recommend the SGD5570NS when view is the priority and the opening's wind load allows it.
Yes. The SGD5570NS carries an LMI impact rating and is HVHZ-certified for High-Velocity Hurricane Zone installations in Miami-Dade and Broward. It's rated to a design pressure of +60/-70 psf. We'll confirm the current product approval and verify the rating fits your specific opening at the time of quote.
The SGD5570NS supports up to 8 panels on as many as 4 tracks, with individual panels up to 60 inches wide and 120 inches tall. We install it in bypass, pocket, and 90- or 135-degree corner configurations. We'll measure your opening and confirm the panel layout that works for your span at the free estimate.
The SGD5570NS offers PGT's Energy Shield, Energy Shield Max, and SolarControl LowE2 glass packages, with optional argon fill, on a 1-1/16 inch laminated insulating glass unit. U-factors run from about 0.33 to 0.38 and SHGC from about 0.17 to 0.30 depending on glass and grids. For the lowest solar heat gain we'd recommend the Argon/SolarControl LowE2 package.
The SGD5570NS frame comes in White (standard), Beige, Bronze, and Black, plus Black/White and Bronze/White two-tone combinations. It comes standard with a dual-point locking mechanism, heavy-duty quad rollers, hidden installation screws, and raised pull handles, with recessed pulls available. We'll help you match the finish and hardware to your home at the estimate.
WinGuard Vinyl is the vinyl version of PGT's flagship impact line and the best-selling impact vinyl in the country. It carries the same Diamond Glass laminated impact glazing and HVHZ approvals as the aluminum line, but on a 3-1/2 inch welded vinyl frame that insulates better and never needs paint. The difference comes down to span and pressure: aluminum handles the oversized and highest-load openings, vinyl handles the rest at a lower installed cost. Many projects use both under the WinGuard name.
Yes. WinGuard Vinyl is large-missile impact-rated and eligible for Miami-Dade and Broward HVHZ installation, carrying Miami-Dade Notices of Acceptance across its operation styles. It's the line we install most often on standard South Florida residential replacements because it clears the code, costs less than aluminum, and runs tighter thermally. The exact wind rating depends on the size and configuration, which we confirm on the quote.
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.
