EAS 623 Bertha Vinyl Impact SGD

EAS's vinyl impact sliding glass doors, including the Bertha-branded 623 SGD.

Bertha-branded vinyl impact sliding door up to 16 by 8 feet in OX, XO, OXO, and OXXO panel configurations. Anti-lift devices, optional keyed handle set.

Impact Rating LMI Design Pressure +65/-65 psf Florida Made in Florida

Impact protection, built for South Florida

The 623 Bertha is the vinyl slider in the EAS door catalog, and it carries the Bertha name that anchors EAS's impact reputation. It is a vinyl impact sliding glass door for HVHZ residential, sized up to 16 feet wide by 8 feet tall in OX, XO, OXO, and OXXO configurations, with anti-lift devices on the panels and an optional keyed handle set. Rated to 65 psf with LMI impact certification, it brings a wide patio opening into the hurricane zone on a vinyl frame.

Armor Pro specs the 623 Bertha when a project wants a vinyl patio slider, usually to match Bertha or 143 Series vinyl windows and to keep the thermal and cost advantages of vinyl over aluminum. For higher design pressures or the heaviest panels, the aluminum FD 8100 is the step up; the 623 is the vinyl slider for the everyday HVHZ patio opening.

Frequently Asked Questions

The 623 Bertha is Eastern Architectural Systems' vinyl impact sliding glass door for residential HVHZ installations, carrying the Bertha name that anchors EAS's impact reputation. It's available in OX, XO, OXO, and OXXO panel configurations and brings a wide patio opening into the hurricane zone on a vinyl frame. We spec the 623 Bertha when a project wants a vinyl patio slider, often to match Bertha or 143 Series vinyl windows and to keep the thermal and cost advantages of vinyl over aluminum.

Yes. The 623 Bertha carries Large Missile Impact (LMI) certification and is HVHZ-approved, making it a true impact door for South Florida coastal and HVHZ residential projects. It's rated to 65 psf design pressure across its configurations. We'll confirm the specific approval and rating for your jurisdiction and opening when we quote the job.

The 623 Bertha sizes up to 192 by 96 inches, which is 16 feet wide by 8 feet tall, in its 3- and 4-panel OXO and OXXO configurations. A 2-panel OX or XO unit reaches up to 144 inches wide, and all configurations are rated to +65/-65 psf design pressure. We measure your rough opening and confirm the panel layout and design pressure your project requires before ordering.

The 623 Bertha uses 1-inch insulated glass packages with argon, available in clear or laminated impact builds. The most efficient option, E340 with argon and clear laminated glass, reaches a U-factor of 0.31 with a 0.13 SHGC, while a clear non-low-E package sits around U 0.44 with a 0.51 SHGC. Because it's a vinyl frame, its U-factors run notably lower (more efficient) than the aluminum sliders, and we'll help you pick the glass that fits your exposure and budget.

The 623 Bertha is offered in White (standard), Desert Sand, or Bronze Exterior with White Interior, with grid options including grids-between-glass, simulated divided light, Colonial, Prairie, and Perimeter. Standard hardware includes fusion-welded structurally reinforced sashes, a dual mortise lock with anti-slam device, stainless-steel dual tandem rollers on precision-ground bearings, a rugged aluminum sill cover, and anti-lift panel devices, with a keyed handle set available. It also comes with an easy-rolling, no-jump panel screen with adjustable rollers.

We don't quote a flat price because installed cost depends on the width and panel count, the glass package, and the condition of your opening. The 623 Bertha is EAS's everyday vinyl HVHZ patio slider, generally a more cost-effective and thermally efficient choice than the aluminum line; for higher design pressures or the heaviest panels, the aluminum FD 8100 is the step up. Armor Pro provides a free, no-obligation estimate after measuring your opening.

Two sliding glass doors: the 623 Bertha, EAS's standard vinyl impact patio slider, and the 650 MTD, a premium multi-track pocketing door that stacks panels into the wall for a full indoor-outdoor opening. Both are vinyl-framed and impact-rated for South Florida. They are the warm, value side of the EAS door catalog and a natural match to EAS vinyl windows.

Yes. Both vinyl doors are impact-rated and carry statewide Florida Product Approval with an HVHZ-approved designation under the Florida Building Code, the level required for the High-Velocity Hurricane Zone. As with all EAS products, they are approved through the FBC route rather than a separate Miami-Dade NOA, which is accepted in Miami-Dade and Broward. We pull the permit and confirm the approval for your specific door size and configuration.

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.
