Glossary Busters: 2026 Edition – The Window Terms You Pretend to Know (But Don’t)

Let’s be honest for a second.
You’ve heard these words before. You’ve probably nodded along in a consultation. Maybe you even repeated one confidently to a friend.

But do you actually know what they mean?

Welcome to Glossary Busters: 2026 Edition—where we lovingly call out the window terms everyone pretends to understand… and finally explain them without putting you to sleep.

Jambs

No, not fruit-related. 🍓
The jamb is the vertical side of a window frame—the part that gives your window structure and support.

Why it matters:
Jamb depth plays a big role in how (and if) certain window treatments can be installed cleanly and beautifully. Translation: good jambs = better fit, better look.

Palladian Shelf

This one sounds fancy because it is fancy.

A Palladian shelf is the horizontal ledge found in Palladian-style windows (those dramatic, arched center windows with rectangular sides). It’s architectural drama at its finest.

Why it matters:
That shelf affects how shutters, shades, or drapery can be mounted—and getting it wrong is a fast track to awkward installs and design regret.

Motorization

This is where things get fun. 🤖✨
Motorization means your blinds or shades open and close with the touch of a button, an app, or even your voice.

Why it matters:
Convenience. Safety (no cords!). Energy efficiency. And yes—feeling like you live in the future. Once you go motorized, there’s no going back.

Louver

Yes, you’ve heard of louvers… but do you really know them?

A louver is the adjustable slat found in shutters or some shades. They tilt to control light, airflow, and privacy—basically the multitasker of the window world.

Why it matters:
Louver size affects everything from how much light you get to how modern or traditional your shutters look. Tiny detail. Huge impact.

Sill

Simple word. Big importance.

The sill is the bottom horizontal part of your window frame. It supports the window and often plays a role in how treatments are mounted or measured.

Why it matters:
A deep sill? Shallow sill? Decorative sill? All of that influences what works best—and what definitely won’t.

Congrats, You’re Officially “In the Know”
