Frequently Asked Questions
The Pella Defender sliding window is a commercial-grade vinyl impact horizontal roller that opens side-to-side on a track, built on the CWS-6100 vinyl platform at Pella's CWS facility in Ocala, Florida. Because it slides horizontally and reaches wide sizes, it's a strong fit for wide openings and for multi-family and light-commercial residential projects. We install it on Florida coastal buildings where the opening is wider than it is tall.
The Defender slider runs from a minimum of 26.5 by 18 inches up to a maximum of 111 by 72 inches, so it can cover unusually wide openings, and it's rated to a design pressure of +58/-58 psf. The actual design pressure your opening has to meet depends on its size and wind exposure, with the line's tested ratings landing in roughly the 38 to 58 psf range. We confirm the rating your specific slider needs at quote so it clears your permit.
Yes, the Defender slider is Large Missile Impact (LMI) rated for Florida coastal installations and carries Florida Product Approvals FL17355 and FL17793. As part of the Defender line it is built for Florida coastal projects outside the Miami-Dade and Broward HVHZ; for an opening inside the HVHZ we'd point you to an HVHZ-approved product. We confirm the current approval on file against your jurisdiction before pulling the permit.
The Defender slider offers Advanced Low-E, Coastal Low-E, SunDefense Low-E, and Neat Low-E glass, plus obscure, bronze, gray, and blue insulated options, all on the line's impact-resistant laminated insulated glass. Low-E and SunDefense help control solar heat gain in South Florida, while obscure glass is useful for bathrooms and street-facing openings where you want privacy. We'll help you match the glass to each opening's exposure and privacy needs.
The Defender slider can be ordered in all-white, all-bronze, or white-interior-with-bronze-exterior frame finishes, with AutoLock hardware available in white or bronze and an InView flat fiberglass screen. Grilles-between-the-glass are available in 3/4-inch or 1-inch contour, 5/8-inch flat, or a 7/8-inch exterior-applied profile. We'll go over the finish, hardware, and grille options so the sliders match the rest of your windows.
There's no flat price for the Defender slider because the installed cost depends on the width of the opening, the glass and grille package, the frame finish and hardware, and the condition of the existing opening. Wide sliders near the 111-inch maximum and upgraded glass are the main factors that move the quote. Armor Pro gives a free, no-obligation estimate and will measure your openings before pricing the windows.
No. Defender is impact-rated vinyl, but it carries Florida state-level product approvals rather than a Miami-Dade NOA, so it is for Florida coastal work outside the High Velocity Hurricane Zone. That covers the large band of the state that requires impact glazing but not a full HVHZ approval, such as the Treasure Coast and Gulf Coast counties. For HVHZ multi-family or residential work, the product moves to an HVHZ-certified line such as HurricaneShield. We confirm which approval your county requires before specifying it.
Both are Pella vinyl impact lines built in Ocala on a related platform, but they're aimed at different jobs. Defender is the commercial-grade line, channeled toward multi-family and light-commercial buildings, with a heavier frame and light-commercial AAMA performance grades, but it stops short of HVHZ approval. HurricaneShield is the residential line and is the one carrying the Miami-Dade and Broward HVHZ certification. For a single-family hurricane-zone home we use HurricaneShield; Defender is for buildings rather than houses, outside the HVHZ.
Pella Corporation is a family-owned national manufacturer headquartered in Pella, Iowa, founded in 1925 and now spanning more than 20 plants across the country. For the Florida hurricane market the important detail is that Pella's impact lines, HurricaneShield and Defender, are built in Ocala, Florida by Pella's CWS subsidiary, so the storm products are made in-state rather than shipped in. We install and service Pella across South Florida and handle the order, permit, and installation regardless of which plant a given product comes from.
