When you are building a new house or taking an older home down to the studs, you have a massive opportunity. Because the walls are completely open, you aren’t stuck dealing with the tiny, inefficient window frames the original builder chose twenty years ago. You get to start fresh.
But looking at window catalogs can be overwhelming. Manufacturers throw a lot of technical jargon at you, and it is easy to end up overpaying for features you don’t need—or worse, underpaying and ending up with windows that turn your house into an oven every July.
If you are trying to figure out which new construction windows make the most sense for your Las Vegas project, here is a straightforward guide on what to look for, what to avoid, and where you should actually spend your budget.
The “Nail Fin” Advantage: Why Not Just Buy Standard Windows?
First, let’s clarify why you need this specific type of window for a major build. Homeowners often ask us if they can just buy standard replacement windows (also known as retrofits) and use them in a new wall. The short answer is no, and here is why.
Standard replacement windows are designed to slide into a wooden frame that is already finished with exterior stucco or siding. New construction windows, on the other hand, come with a built-in plastic or metal flange around the outside edge called a “nail fin.”
When your wall framing is completely exposed, our installers push the window into the rough opening and nail that fin directly into the wooden studs. We then cover the entire fin with heavy-duty, rubberized flashing tape before the exterior stucco, brick, or siding ever goes up.
This creates an airtight, watertight structural bond. It stops desert dust from blowing through the cracks, prevents water leaks during monsoon season, and actually bolsters the overall strength of the wall.
Where to Focus: Frame Materials
The frame you choose dictates how long the window will last, how much maintenance it will need, and how it handles the intense Nevada sun.
Vinyl Frames
This is the most popular choice for modern builds, and for good reason. High-quality vinyl doesn’t warp, rot, or need to be repainted. It also has excellent insulating properties. Unlike metal, vinyl doesn’t conduct heat, keeping the outside temperatures from transferring through the frame into your drywall. Just make sure you are buying premium vinyl with UV inhibitors, so the frames don’t fade or crack after a few years in the sun.
Aluminum Frames
Older aluminum windows get a terrible reputation because they act like giant heat conductors. If you touch an old aluminum frame in the summer, it will burn your hand. However, modern, thermally broken aluminum frames are different. They have a barrier inside the metal that stops the heat transfer. Builders love them because aluminum is incredibly strong, which allows for massive, ultra-thin modern window designs that you just can’t build out of vinyl.
Wood and Fiberglass
Wood frames look beautiful on the inside, but they require a lot of maintenance to keep them from drying out and cracking in our desert climate. Fiberglass is incredibly durable and can be painted, but it comes with a massive price tag. For 90% of Vegas homes, premium vinyl or thermally broken aluminum is the smarter investment.
The Glass is Where You Save Money
You can buy the most expensive, heavy-duty frame in the world, but if you put cheap glass in it, your summer power bills will still be through the roof. When selecting new construction windows, the glass package is where you should focus your spending.
- Insulate with Dual-Pane: Never install single-pane glass in a new build. Always opt for dual-pane insulated units. The small pocket of space between the two pieces of glass stops the heat dead in its tracks.
- Reflect Heat with Low-E: Low-Emissivity (Low-E) glass has a microscopic metallic coating baked right into it. It allows visible sunlight in but acts like a mirror to invisible UV and infrared heat rays, bouncing the heat back outside. This keeps your furniture from fading and gives your AC unit a massive break.
- Block Noise with Argon Gas: To get the maximum performance out of a dual-pane window, we use units filled with Argon gas. Because it is denser than standard air, it slows down heat transfer even more and is excellent at dampening street noise if you live near a busy road.
Understanding Window Energy Ratings
When you look at the sticker on a new window, you will see a bunch of numbers. You only really need to care about two of them when building in Las Vegas:
- SHGC (Solar Heat Gain Coefficient): This measures how much solar heat the window blocks. The lower the number, the less heat gets into your house. In Nevada, you want this number to be as low as possible (ideally below 0.25) to keep your cooling costs down.
- U-Factor: This measures how well the window insulates. Again, lower is better. A low U-factor means the cool air your AC is pumping out isn’t escaping through the glass.
Picking the Right Operating Styles
Because you are installing new construction windows into open framing, you have complete design freedom. You don’t have to put the same type of window back in the same spot. You can completely change the architectural feel of the house just by playing with the window styles.
- Single and Double-Hung: These slide up and down. They are classic, easy to clean, and great for bedrooms.
- Horizontal Sliders: The standard Vegas window. They slide side to side and are perfect for wide openings where you want a lot of ventilation.
- Casement Windows: These crank open outward on a hinge, like a door. They are fantastic for catching a breeze and actually seal tighter than sliding windows when locked, making them highly energy-efficient.
- Picture Windows: These are large panels of glass that do not open at all. If you have a wall facing the mountains or the backyard, ditch the sliders and have your framers install a massive picture window to open up the room.
Don’t Forget About Your HOA
If you are building a custom home or adding an addition in a master-planned community like Summerlin or Henderson, you need to check your HOA guidelines before you order anything. Many local HOAs have strict rules on window frame colors, grid patterns (the little bars inside the glass), and even the reflectivity of the glass tint. Get your window specs approved first so you don’t end up having to rip brand-new windows out of your walls.

Frequently Asked Questions
Are new construction windows more expensive than standard replacements?
The physical window itself costs about the same as a standard retrofit window. The big difference is the labor. If your walls are already open for a remodel, installing them is actually straightforward and fast. However, if you want new construction windows put into a finished house, the labor costs skyrocket because we have to cut away your stucco to expose the studs, and then you have to hire someone to patch and paint the exterior wall afterward.
Do you handle the wall framing, or do I need a separate contractor?
We specialize in the glass and the window installation itself. If you are keeping the window the exact same size, we handle it all. But if you want to turn a small window into a massive sliding glass door, load-bearing studs have to be cut. You will need a framer or general contractor to build the new “rough opening.” Once they frame it out, we come in, waterproof the opening, and install the new glass.
How long does it take to get custom windows ordered for a new build?
Custom frame sizes take time to manufacture. The biggest mistake homeowners make is waiting until the house is almost framed to start looking at glass. Depending on the manufacturer, the frame material, and the glass package, lead times can be anywhere from 4 to 8 weeks. We always recommend ordering your windows the second your blueprints are finalized.
Can I mix different window styles in the same house?
Absolutely. In fact, it is the smartest way to do it. You might want a giant, fixed picture window in the living room for an unobstructed view, but casement windows in the kitchen so you can crank them open while cooking. We can mix the operating styles while keeping the frame colors and glass tints exactly the same, so the house looks perfectly uniform from the street.
