Black-on-Black NT Twinsulator Aluminum Window Replacement | Oversized Openings Reframed Beyond 120 United Inches
This Round Rock windows project used NT Windows Twinsulator aluminum units, chosen for strength in 100°-plus summers. We installed several openings over 120 united inches, plus new interior sills up to 96 inches. Both exterior and interior were finished in black for a modern, uniform look. The homeowner got tighter, better-performing windows built for the Wildwood neighborhood's aging housing stock.

The homeowner found us through an internet search and reached out on March 4, 2026. We talked through the goal early: replace aging windows with a modern black-on-black look built for Central Texas heat. By March 5, the job moved into our prospect stage.
Our window technician measured each opening during the assessment, flagging several that ran over 120 united inches. That measure step shaped the order, since oversized units and extra framing had to be planned in advance. We confirmed both exterior and interior would finish in black.
The homeowner approved the project on March 16, 2026, locking in the NT Twinsulator aluminum units and black finish. We placed the window order in late March. Scope included interior sills up to 96 inches, framing materials, and all installation supplies.
The windows arrived in early May, and we installed them over the days around May 10, 2026. The crew set both standard and oversized aluminum units, reframing openings as needed and adding fresh interior sills. Framing and trim labor rounded out the finished look.
We wrapped the installation and invoiced on May 10, 2026, leaving the home with uniform black windows inside and out. Cleanup, delivery, and dump fees were all handled within scope. The project officially closed on May 27, 2026.
We swapped out the tired windows on a Wildwood home in Round Rock for NT Twinsulator aluminum windows in a full black-on-black finish, wrapping the whole job in a single install push in early May.
The existing windows had aged past their useful life, which is common for the older homes across Wildwood. Drafty frames and worn seals let Central Texas heat push right into the living space.
Aluminum gets a bad rap for older, drafty designs, but the windows we chose here are a different animal. The NT Twinsulator line uses a thermally broken frame, which stops heat from riding straight through the metal into the house. That matters a lot in Round Rock, where summer days sit above 100° for weeks at a time. Aluminum also holds its shape under that constant heat load better than many alternatives, so the frames stay square and the seals keep sealing. For a homeowner who wanted crisp black lines and long-term strength, it was the right call over a softer material.
We handled the whole job in a focused push once the units arrived, tackling both standard and oversized openings. Framing and trim labor made up a real chunk of the work here, since the larger windows needed proper support.
Once we pulled the old units, the crew took a close look at each opening before setting anything new. A few of the larger spans needed extra framing attention to carry the weight and keep everything plumb. That is where a lot of DIY and budget installs go wrong — people slide a new window into an out-of-square opening and wonder why it leaks air a year later. We reframed and squared each opening first, then set the window, then trimmed it out clean. The interior sills up to 96 inches got fresh material so the finished look matched the new black frames instead of clashing with old wood.
The home now has uniform black windows inside and out, with tighter frames ready for the next Texas summer. The oversized openings look intentional and finished rather than patched.
The homeowner became a prospect on March 5, 2026, and approved the work on March 16. Windows were ordered in late March, arrived in early May, and went in shortly after. The file closed on May 27, 2026.
Aluminum frames stay dimensionally stable through the long stretches of 100°-plus heat we see here. Paired with a thermal break, they resist warping while still fighting heat transfer into the home.
This retail job landed in the $15k–$20k range. That covered material, framing and trim labor, oversized-unit installation, interior sills, and cleanup fees.
Yes. On this job we installed units both under and over 120 united inches, reframing where needed. Larger openings are routine for us — reach out through Austin Pro to talk through yours.
