Overview

About the 176 Series Bertha

The 176 Series Bertha is EAS's flagship, the vinyl impact line built specifically for the HVHZ and carrying Made-in-the-USA certification. Three operation styles (single hung, horizontal roller, and picture) cover the bulk of a residential replacement, with the single-hung rated to 120 psf and an optional SentryGlas Plus glazing upgrade that lifts the roller and picture variants to the same 120 psf ceiling. The headline that sells it, though, is the warranty: a lifetime guarantee on both the vinyl frame and the insulated glass, unusually long for an impact window.

Armor Pro specs the 176 Bertha on HVHZ residential replacements where a homeowner wants a Florida-made vinyl impact window with a strong warranty at a regional-brand price. The line keeps the catalog tight, the common window openings rather than doors, so for patio doors a project pairs it with the EAS aluminum or vinyl door lines, and for casement and awning operations the 143 Series covers those.

Frequently Asked Questions

The 176 Bertha is EAS's flagship vinyl impact window line, built specifically for Florida's hurricane zone on a 3-1/4 inch fusion-welded frame with a 0.070 inch wall thickness. It comes in three operation styles, single hung, horizontal roller, and picture, which cover most of the window openings on a typical home. It is the EAS vinyl line to reach for when you want the highest performance and the strongest warranty in their vinyl catalog.

The single-hung is rated up to 120 psf design pressure, the highest in the EAS vinyl portfolio. The horizontal roller and picture models run lower at their base spec but can be uprated to the same 120 psf with an optional SentryGlas Plus (SGP) glass interlayer, which is stiffer than standard laminated glass. Design pressure is what determines how much wind load a window can take, and the right rating depends on your opening's size and exposure, which we confirm on the quote.

Yes. The 176 Bertha is impact-rated and carries statewide Florida Product Approval with an HVHZ-approved designation under the Florida Building Code, which is the certification level required for the High-Velocity Hurricane Zone. EAS approves it through the FBC route rather than a separate Miami-Dade NOA; that FBC HVHZ approval is accepted in Miami-Dade and Broward, and we handle the permit and approval paperwork as part of the install.

The 176 Bertha carries a lifetime limited warranty on both the vinyl frame and the insulated glass. Extending lifetime coverage to the glass, not just the frame, is unusual for a vinyl impact window and is one of the main reasons homeowners step up to the Bertha line over EAS's value-tier 143 Series. Warranty terms are set by EAS; we register the product and support any claim.

The 176 Bertha comes in White, Desert Sand, and Bronze, plus a Black laminate exterior option that the value-tier 143 Series does not offer. For glass, it uses laminated impact glass, with an optional SentryGlas Plus interlayer on the roller and picture models that both raises the design pressure and allows larger sizes. You can preview frame colors and styles in our Window and Door Designer and Visualizer before you commit.

No. The 176 line keeps a tight catalog of three styles, single hung, horizontal roller, and picture. For HVHZ casement and awning windows, EAS covers those under the 143 Series with impact certification added, and the EAS vinyl catalog has no hurricane-rated double-hung at all. On a whole-home project we mix the lines so each opening gets the right style, and we will flag any opening EAS cannot cover.
