Frequently Asked Questions
The SH5500 is the flagship single-hung window in PGT's WinGuard Vinyl line, built on a 3-1/2 inch welded vinyl frame with SecureConnect corner keys and an integrated aluminum interlock for rigidity. The bottom sash operates while the top stays fixed, and the sash tilts in so you can clean the exterior glass from inside. We install it as a workhorse impact window for bedrooms, living areas, and most standard openings.
Yes. The SH5500 uses Diamond Glass laminated glazing, carries an LMI impact rating, and is HVHZ-certified for High-Velocity Hurricane Zone installations under Miami-Dade NOA 25-0520.01 (valid through July 30, 2030) and Florida Product Approval FL239.R30. We install it throughout Miami-Dade and Broward and confirm the active approval on your quote.
The SH5500 is built up to 52.125 inches wide and 84 inches tall in standard configuration, with a custom-sash option reaching 91.813 inches tall. It carries a design pressure of +70/-110 psf. We'll measure your opening and confirm the size and rating it needs at the free estimate.
The SH5500 comes standard with ComfortLift handles and a constant-force balance system to ease sash operation, with a spiral balance system on larger sizes. The bottom sash tilts in for cleaning the outside glass from inside the home. Options include a vent latch, a Window Opening Control Device meeting ASTM F2090, and upgraded handle finishes.
The SH5500 offers PGT's Energy Shield, Energy Shield Max, and SolarControl LowE2 glass, with optional argon fill, all on a 1-inch laminated insulating glass unit. U-factors run from about 0.29 to 0.33 and SHGC from about 0.18 to 0.31 depending on glass and grids. For the lowest solar heat gain we'd recommend the Argon/SolarControl LowE2 or Argon/Energy Shield Max package.
Yes. The SH5500 is tested for 24 different anchor conditions across concrete/CMU and wood substrates, with both through-frame and integral-fin installation methods on file. That gives us flexibility to install it correctly in South Florida block homes as well as wood-framed walls. We confirm the right anchorage detail for your wall during the site assessment.
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.
