EAS's catalog covers five window families and five door families across vinyl and aluminum frame materials.

Aluminum and vinyl sliding glass doors span the 623 Bertha vinyl, 650 multi-track pocket SGD, and the 6000, 7000, and FD 8100 aluminum series, with the FD 8100 covering premium configurations.

EAS also publishes an extensive 288-post technical blog covering energy efficiency, hurricane preparation, Florida regulatory topics, and homeowner-facing window education, a depth of content marketing rare among Florida manufacturers. Armor Pro installs EAS products across South Florida, with the 176 Bertha line and FD 8100 sliding door particularly suited to coastal residential projects.

When the homeowner or builder sees the high quality, rigorous process our windows go through, they won't want to go anywhere else.

Frequently Asked Questions

Eastern Architectural Systems (EAS) is a Florida manufacturer based in Fort Myers, with roots in the Eastern Metal Supply family. It builds vinyl and aluminum impact-resistant windows and doors for the Florida residential market, and is the maker of the Bertha impact line. EAS has been part of Cornerstone Building Brands since late 2023, though it still operates under its own brand. We install and service EAS products throughout South Florida.

Most of the EAS impact lines carry statewide Florida Product Approval, and the impact-rated models hold an HVHZ-approved designation under the Florida Building Code, which is the high-wind certification level for the High-Velocity Hurricane Zone. Exact ratings depend on the specific model, size, and glass package, so we confirm the approval that applies to your opening when we put together the quote.

No. EAS approves its products through the statewide Florida Building Code (FBC) route with an HVHZ-approved designation rather than pursuing separate Miami-Dade Notices of Acceptance (NOAs). That FBC HVHZ approval is code-sufficient and is accepted in Miami-Dade and Broward. The one thing to know is that if a project's specifications specifically require a Miami-Dade NOA number on file, EAS does not carry one, in which case we will tell you up front and can point you to a line that does.

We install across the EAS catalog: the 176 Series Bertha and 143 Series vinyl windows, the 3000 Series and FWI 1000 Series aluminum windows, and both the aluminum doors (6000, 7000, FD 8100, and 5000 French) and the vinyl doors (623 Bertha and the 650 multi-track pocketing slider). We help you pick the line that fits the opening, the exposure, and the budget rather than steering you to one product.

Vinyl (the 143 and 176 Bertha lines) is the lower-cost, better-insulating choice and covers most standard residential replacements. Aluminum (the 3000 and FWI 1000 lines) is stronger per inch of frame, so it carries higher design pressures and larger glass than vinyl can in the same size, which matters on the most exposed elevations, high-rise faces, and large openings. We match the material to the wind load and size of each opening, so a single home sometimes uses both.

EAS offers a lifetime limited warranty on its vinyl window frames, and the flagship 176 Bertha line extends that lifetime coverage to the insulated glass as well, which is unusual at its price point. Aluminum and door warranties vary by line. Coverage terms and registration are set by EAS, not by us; as your installer, Armor Pro stands behind the installation workmanship separately and helps you with any warranty claim.

EAS is a Florida-made line engineered specifically for Florida coastal exposure, and its vinyl impact products tend to price competitively against national brands while still carrying strong warranties, especially the lifetime frame-and-glass coverage on the 176 Bertha. It is a regional-brand value play rather than a luxury or commercial-system play. We will tell you honestly when an EAS line is the right fit and when a different product on our shelf is a better match for your project.
