What Are New Construction Windows?
New construction windows are designed for homes being built from the ground up or undergoing major structural renovations. Unlike replacement windows, which fit into an existing frame, new construction windows attach directly to the wall studs using nail fins, flanged edges around the window frame that are nailed or screwed to the framing before siding is applied.
This direct connection to the structure creates a tighter seal, better insulation, and a cleaner finished look. New construction windows are the standard choice when the wall framing is exposed, whether you're building a brand-new home, adding a room, or doing a full down-to-the-studs remodel.
- Nail fins mount to exposed studs. The flange is fastened to the framing itself, not to an old frame left in place.
- Installed before siding goes on. That sequence is what allows proper flashing and a watertight assembly.
- Standard for new builds, additions and gut remodels. Any project where the framing is open is a new construction window job.
New Construction Windows vs. Replacement Windows
Choosing between new construction and replacement windows depends on your project type. Here's how they compare:

| Feature | New Construction Windows | Replacement Windows |
|---|---|---|
| Installation | Mounted to exposed wall studs with nail fins | Fit inside an existing window frame |
| Best For | New builds, additions, full remodels | Upgrading windows in an existing home |
| Seal & Insulation | Superior, direct structural attachment | Good, depends on existing frame condition |
| Structural Work Required | Yes, studs must be exposed | No, installs without disturbing walls |
| Cost | Typically lower per unit (no retrofit labor) | Higher labor cost due to careful fitting |

Why Window Choice Matters in New Builds
When you're building from scratch, windows are one of the few decisions that affect your home's comfort, energy bills, and value for decades. Here's why it pays to get this right:

Energy Performance Starts at the Glass
In the Bay Area's climate with warm summers and cool, damp winters, energy-efficient new-build windows keep your home comfortable year-round. Features like low-E glass coatings and argon gas fills reduce heat transfer, which lowers your heating and cooling costs from day one.
Building Codes Require It
California's Title 24 energy standards are among the strictest in the country. Every new construction window installed in the Bay Area must meet specific U-factor and Solar Heat Gain Coefficient (SHGC) ratings. Failing to meet these standards means failed inspections and costly delays. Insight Glass guarantees that every window we install is Title 24-compliant.
Long-Term Value
The right windows add curb appeal and boost resale value. Cheap windows installed during construction are often the first things homeowners need to replace. Investing in quality upfront saves money over the life of your home.
Every window we install is matched to your project's Title 24 climate zone before it is ordered, so your build passes inspection the first time.

Frequently Asked Questions About New Construction Windows
Everything Bay Area homeowners and builders ask us about nail-fin windows, brand choices, Title 24 compliance, and cost.
New construction windows are windows built with nail fins (a flanged edge) that attach directly to the exposed wall studs of a home being built or undergoing a major remodel. They're designed to be installed before exterior siding goes up, creating a tight, energy-efficient seal between the window and the wall.
The main difference is how they attach to the house. New construction windows use nail fins and mount to exposed studs. Remodel (or replacement) windows can be installed into an existing window frame without disturbing the surrounding walls or siding. New construction windows generally offer a better seal and greater insulation because they are connected directly to the structure.
The best brand depends on your budget, style, and performance needs. For Bay Area homes, we recommend Milgard for its West Coast engineering and lifetime warranty, Andersen for its range of premium styles, and Amsco for California-built energy efficiency. All three brands manufacture windows that meet California's Title 24 energy standards.
Yes, but only when the wall framing is exposed, typically during a major remodel where siding and interior walls have been removed down to the studs. If your existing window frames are in good condition and you don't plan to open up the walls, replacement windows are usually the better option. We'll help you determine the right approach during your free consultation.
Pricing varies based on window type, material, size, and brand. Vinyl windows are the most affordable option, while fiberglass costs more. We provide free, detailed quotes after assessing your project, no pressure, no obligation. Call us at 707-746-6571 to get started.
Absolutely. All the new construction windows we install feature energy-efficient technologies like low-E glass coatings, argon or krypton gas fills, and insulated frames. Every window meets California's Title 24 energy-efficiency requirements, helping reduce your heating and cooling costs from the day you move in.
