Frequently Asked Questions

The FWI 1000 SH is Eastern Architectural Systems' flagship aluminum impact single-hung, where the bottom sash raises to open while the top stays fixed. It's built on a 3-1/4-inch aluminum frame with stainless-steel components, preloaded spring balancers, and double-veined felt seals for long-term coastal performance. We install it when an opening calls for the strongest single-hung EAS makes, especially on exposed or high-wind elevations.

The FWI 1000 SH is rated to 120 psf positive and 150 psf negative design pressure, the highest pressure rating in the entire EAS catalog. It carries Large Missile Impact (LMI) certification and is HVHZ-approved for South Florida coastal installations. We'll confirm the specific approval and the rating your opening requires at quote.

The monolithic impact single-hung reaches up to about 53-1/2 inches wide by 77 inches tall at the full +120/-150 psf rating, while the insulated-glass version maxes at 48 inches wide by 72 inches tall and is rated to +80/-100 psf. We measure your rough opening and confirm whether the monolithic or insulated build best fits your size and design-pressure needs before ordering.

The FWI 1000 SH uses laminated impact glass, and its top-rated package is built with an SGP (ionoplast) interlayer, which is stiffer and stronger than standard PVB and supports its 150 psf negative design pressure. Options run from 5/16-inch laminated builds up through 7/8-inch insulated laminated packages with argon. The most efficient option, E340 with argon, reaches a U-factor of 0.6 with a 0.16 SHGC, and we'll walk you through the makeup for your order.

The FWI 1000 SH is offered in White (standard) or Bronze aluminum, with grid options including flat muntin, profile muntin, Colonial, Prairie, and Perimeter. Standard features include preloaded spring balancers, stainless-steel components, and double-veined felt seals, with insulated glass available as an upgrade. We'll match the finish and grid pattern to the rest of your project.

We don't quote a flat price because installed cost depends on the size of the opening, the glass package (monolithic versus insulated), and the condition of your existing frame. The FWI 1000 is EAS's highest design-pressure aluminum impact line, so it's a premium choice built for the most demanding coastal exposures. Armor Pro provides a free, no-obligation estimate after measuring your opening.

The FWI 1000 is EAS's highest-performance aluminum impact window line, the strongest the company makes. It is built on a 3-1/4 inch aluminum frame with stainless-steel components, double-veined felt seals, and removable operating sashes for easy cleaning. It comes as a single hung and as a horizontal roller, including an enhanced HRP roller variant for the most demanding openings.

The single-hung is rated to 120 psf positive and 150 psf negative, the highest design pressure in the entire EAS catalog. The horizontal roller is rated to 100 psf positive and 120 psf negative. Aluminum carries these higher pressures because the extrusion is stiffer than vinyl per inch of frame, which is why we reach for the FWI 1000 on the most exposed elevations and tall or wide openings.

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.
