Overview

About the Defender Series

Defender is the Pella line for buildings rather than houses. It is commercial-grade vinyl impact, built in Ocala on the same CWS-6100 platform that underpins CWS StormStrong, and channeled toward multi-family residential and light-commercial projects. The five operation styles (single hung, double hung, sliding, direct-set fixed, and architectural shapes) cover the repetitive openings of an apartment or condo elevation, and the heavier commercial frame carries the design pressures those buildings need.

Defender is LMI impact-rated for Florida coastal installations outside the Miami-Dade and Broward HVHZ, which places it on the large band of the state that requires impact glazing but not a full Miami-Dade NOA. Armor Pro specs Defender on multi-family and light-commercial work that wants the Pella name and a commercial vinyl impact window at volume. For single-family HVHZ residential, HurricaneShield is the right Pella line; for HVHZ multi-family specifically, the product moves to a Miami-Dade-certified system.

Frequently Asked Questions

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.

Defender's design pressures run from roughly 35 to 58 psf depending on the style, on light-commercial performance grades suited to the repetitive openings of an apartment or condo elevation. The line covers single-hung, double-hung, sliding, direct-set fixed, and special architectural shapes. The wide sliding window is a standout for multi-family corridor and patio applications. The exact rating depends on size and configuration, which we confirm on the quote.

Yes, within its non-HVHZ coverage area. Defender uses laminated impact glass with a polymer interlayer, so the window resists wind-borne debris and stays sealed without anyone closing a shutter, plus a Low-E and argon glass package for energy. It still has to clear the design-pressure requirement for your address, and because it's a non-HVHZ product we confirm the rating works for your county's code before ordering.
