Impact Window Wall
A pre-assembled impact window wall shipped as finished cassettes, which cuts the volume of site glazing work on a coastal high-rise or multifamily envelope. Reinforced framing and multi-layer laminated impact glazing throughout, with unit sizes drawn to the floor-to-floor dimension. Tested to the Florida Building Code TAS protocols; approvals vary by jurisdiction, so send us the project location and we will confirm what applies there.
Configure your unit, then request a quote — we price it and reply, usually within one business day.
Every unit is made to the opening. Sizes confirmed at quotation.
Low-E1 / E2 / E3 coatings, laminated and tempered build-ups available. We recommend the coating for your climate zone.
No price is shown because every unit is made to order. You will get a written quote for exactly this configuration.
10-year warranty · 20-year transferable upgrade available
Questions before you order
Will these pass a Florida HVHZ inspection?
This model is not covered by a Miami-Dade Notice of Acceptance, and we do not present it as if it were. We hold active NOAs on hurricane-zone systems — casement, fixed, awning, sliding glass door and storefront — and will tell you which one fits your opening if your job is in HVHZ. We do not claim an impact rating on a product that has not been tested for one; that is exactly what fails an inspection.
Do I get stamped drawings and the approval number before I order?
Yes — with the quotation, not after the order. Shop drawings carry a Florida-licensed engineer of record’s seal, and if the system holds a NOA, the exact number covering your opening is issued in writing at that same point. A supplier who only produces drawings once you are committed has moved their risk onto your schedule; here the paperwork arrives before the decision, not after it.
What happens if a unit arrives wrong — who pays for the delay?
We do. If a unit does not match your approved drawings, or has a manufacturing defect, we replace or repair it at no cost to you — send the order number and photographs and we start it the same day. The honest constraint worth knowing: a replacement is manufactured and shipped like any other order, so the realistic timeline is production plus freight, not days. That is the strongest argument for ordering a small contingency on a large project.
Can you meet a 9-week schedule, or is that best-case?
It is the figure we confirm in writing before deposit, against a real production schedule — not a best-case number used to close the sale. 9–10 weeks door to door already includes production, ocean freight, customs and final delivery in one figure. That said: non-standard sizes, special finishes and large combinations do take longer in production, and we say so at quotation, not after you have already paid a deposit.
Who holds the warranty — you, or someone overseas?
We do. One company on the contract, one warranty, one point of contact — you deal with NEXWD from the quotation through to a claim years later, and there is no second party on the other side of the world for us to hand you off to. Ten years standard on frame, hardware and screens; an optional 20-year upgrade on glass, transferable without proration. Ask this question of every supplier you are comparing — the answer tells you more than any brochure.
Do you provide CAD/BIM for my submittal?
Yes, free, and at quotation — drawn from our own production drawings, not a generic template, and not gated behind an account or a minimum order. NFRC data, size-versus-pressure tables and section details are included.
Overview
A pre-assembled window wall on a 4 5/16" system depth, shipped as finished units that clip together on site rather than being glazed piece by piece off a lift. The catalogue sets its application by height: at 13 feet and under, this is the platform. That covers ground-floor retail, podium levels and floor-to-floor bays on a multifamily or hotel envelope, where the wall is non-load-bearing and hangs off the building structure.
Two comparisons decide whether this is the right unit. Within the impact range it is the fixed-envelope half, drawn to the floor-to-floor dimension, where the 128 casement is the operable vent you add where a room needs one. Within the window-wall family it is the shallowest and shortest-span member: the 110S runs 4 5/16" deep to 13 feet, while the commercial 120S goes 4 3/4" deep to 14 feet and the 150S to 24. Going up the range buys height and wind rating; staying on the 110S buys the pre-assembled, clip-together install.
The section is 4 5/16" deep in both the vertical and the plan direction, with 1 3/4" face widths at head, sill and jambs and 2 1/2" at intermediate transoms and mullions, so the perimeter reads narrower than the internal grid. The alloy is 6060-T66 with main load-carrying parts at 2.0 mm or thicker and a nylon PA66 thermal break separating the indoor and outdoor profiles. The installation details draw a 6 mm low-e outer pane, a 12 mm argon cavity and a 6 mm inner pane, held by EPDM gaskets and a pressure plate, with the stainless bolts and corner connectors concealed inside the beam. On site the units clip directly together, the visible faces are brought flush and the joint is nailed off; the catalogue reports contractors surveyed saying they could halve the number of installers on the joining system.
On storm performance, the units are tested to the Florida Building Code, 8th edition, under the TAS 201 impact, TAS 202 structural and TAS 203 cyclic pressure protocols, and to large-missile impact for Zone 4, Missile Level D at 50 ft/sec. Approvals are jurisdiction by jurisdiction — send us the project location and we will confirm in writing what applies there before you specify. Glazing is double or triple pane, with an insulating laminated unit where impact resistance and sound damping both matter; the picture-lite rows print a 0.31 U-factor and 0.25 SHGC double-glazed, 0.25 and 0.23 triple. Where local code calls for different ratings, different glass specifications are available.

Mounting and frame options
The frame type decides the rough-opening detail, the flashing and how much of the existing wall has to come out. Four are available; tell us the wall build-up and we will specify which one your opening needs.
The standard new-construction frame. The flange laps the sheathing so the unit sets and seals in one operation.
A 1 3/8" flange is available where the cladding build-up needs the extra reach.
Installs over an existing aluminum window frame, so the stucco exterior is left intact. No cutting back and repatching.
Available on selected window types — ask us which of your openings can take it before you price the stucco work.
For full removal, when the existing frame is rotten or damaged and has to come out entirely.
Sets into the existing rough opening, and arrives with the through-the-jamb holes pre-drilled and the screws supplied.
Straps fix to the frame, which lets the unit sit anywhere in the depth of the wall cavity rather than at a fixed setback.
Installs from the interior, and works for both new construction and replacement.
Full CAD details for any of these are available on request for your wall assembly.
Factory-joined combinations for large openings
Multi-unit combinations are joined in the factory and delivered as one assembly, so the joint is made under shop conditions instead of on a scaffold. The joining mullion is 1 1/8" (28 mm) wide and comes in three reinforcement grades, chosen by the height of the window it has to carry. The system is covered by a US patent.
| Suggested window height | Joint width |
|---|---|
| up to 9 ft | 1 1/8" (28 mm) |
| 9 to 11 ft | 1 1/8" (28 mm) |
| 11 to 13 ft | 1 1/8" (28 mm) |
Combinations arrive partly or fully assembled depending on size and shipping method. Tell us the opening and we will confirm which grade your height needs and how the unit will be split for transport, before you price the crane time.

NFRC certified performance
Certified figures from the NFRC Certified Products Directory — the source a U.S. building department will check. This window is certified separately as a fixed lite and as an operable lite, so both are shown: the operable sash carries the hardware and the operating joint, which costs a little thermal performance.

Impact & hurricane certification
Designed for high-risk hurricane zones such as the south-eastern coasts and the islands, the impact line uses multi-layered laminated and tempered glass in reinforced frames, and is certified under Miami-Dade County Notices of Acceptance for impact resistance, water tightness and air infiltration — the hardest fenestration approval in the United States.
Testing follows the Florida Building Code, 8th edition (2023). All units undergo TAS 201 (impact), TAS 202 (structural) and TAS 203 (cyclic pressure), and are rated for Zone 4, missile level D at 50 ft/sec — the large-missile requirement for a High Velocity Hurricane Zone.
Approval numbers available on request — contact us for the current NOA documentation for your configuration and size.
We hold six active Miami-Dade County NOAs across the range, but a NOA is scoped to a series and a configuration, and this particular system is not inside one of them — it is approved through Florida DBPR and tested to the TAS protocols instead. Approval is granted jurisdiction by jurisdiction, so tell us the project address and we will confirm in writing what applies there before you specify it. If the opening must sit under a NOA, we will point you to the system that does.
