Smart glass
without the wires.

We're the only fabricator routing the electrical channels directly through the steel frame. The result is switchable privacy glass and projection-ready surfaces with no visible wiring — anywhere.

Talk to Us About Your ProjectHow It Works
The problem we solved

Smart glass — the kind that turns from clear to frosted at the touch of a button, or doubles as a high-definition projection surface — has been around for years.

The trouble has always been the wiring. Most installations need surface-mounted conduit, visible junction boxes, or compromises hidden in the trim.

“We took it apart and rebuilt it from the frame in.”

Try it

Clear, frosted,
or anywhere in between.

Tap the switch to flip the glass between states. In real installations this is controlled by the same switch as your lighting, an app, a sensor, or your home automation system.

How it works

The electrical pathway runs inside the steel itself.

During fabrication, we route the electrical pathways through the inside of the steel itself. The wiring runs from the glass, through the frame, and out at the install point — invisible from every angle. The finished assembly looks like a standard steel-and-glass door or window. Tap the switch, and the glass changes state.

There are no surface-mounted wires. No conduit. No visible terminals. Just clean architecture.

Use cases

Where it earns its place.

Privacy on Demand

Master bathrooms, primary suites, executive offices, glass-walled conference rooms. Clear when you want the light. Frosted when you want the privacy.

Projection Surfaces

Home theaters, design studios, retail displays. The same panel that frames the view becomes a 4K projection screen.

Selective Transparency

Wine rooms, gallery walls, art installations — controlled visibility on a schedule, sensor, or app.

What makes ours different

Five things you won't get anywhere else.

01

Zero visible wiring.

Full stop.

02

Integrated at fabrication.

Not retrofitted. Not surface-applied. Engineered into the frame from the beginning.

03

Compatible with all our doors and windows.

Pivot, casement, fixed, partition — any assembly we build can be specified with smart glass.

04

Controlled however you like.

Wall switch, mobile app, motion sensor, scheduled automation, or your existing home system.

05

Built and tested in Dallas.

Every smart-glass assembly is wired, switched, and verified at our shop before it ever leaves the building.

A note on availability

This is custom work.

Integrated smart glass adds about two weeks to our standard lead time — plan on roughly 8–9 weeks from final design to delivery. Bring us your project early.
