Inside vs. Outside Mount: How to Choose the Right Option for Cellular Shades in Meridian Homes

One of the most common questions we get during consultations is:
"Should my cellular shades be mounted inside the window frame or on the wall above it?"

The short answer? It depends. Each mounting style has pros and cons, and the right choice often comes down to:

• Window depth

• Trim style

• Light gaps

• Functionality

• Design preference

Here’s what guides us in deciding what’s right for your home.

🪟 What Is an Inside Mount?

An inside mount means the cellular shade is installed within the window frame. It sits flush with the wall and often shows off more of your window’s trim and architecture.

✅ Pros of Inside Mount:

• Clean, streamlined look

• Keeps the trim and casing visible

• Ideal for windows with enough depth (usually 1½"–2" minimum)

• More secure if layering with drapery or valances

⚠️ Considerations:

• Light gaps on the sides (normal and expected)

• Requires sufficient window depth for proper operation

• There may be inconsistent light gaps from uneven window openings. This happens more often in drywall window openings instead of window openings that are framed out.

🧱 What Is an Outside Mount?

An outside mount means the shade is installed on the wall or trim around the window.

✅ Pros of Outside Mount:

• Provides maximum light blockage and privacy

• Covers imperfect or shallow window frames

• Can visually enlarge small windows

• Necessary for French doors or casement windows

⚠️ Considerations:

• May hide decorative trim

• Projects slightly into the room

• Needs flat mounting space above or around the window

🧠 What Factors Into the Right Mount for Your Home?

1. Window Depth

• If your window frame is deep enough, an inside mount is often preferred for its sleek look.

• Shallow frames (common in older Treasure Valley homes, especially in casement windows with cranks) may require outside mounting.

2. Light Control and Privacy

• Outside mount offers better room-darkening, especially for bedrooms or nurseries.

• Inside mount lets in a little light around the edges, but many homeowners find it sufficient for most rooms.

3. Design Preference

• Want a minimalist or modern look? Inside mount usually wins.

• Want to hide old or unfinished window frames? Outside mount can provide a cleaner visual finish.

4. Layering With Other Treatments

• If you're planning to layer with curtains or drapery panels, an inside mount lets everything stack neatly.

🧩 Your Best Option Might Be a Mix

Many Boise homeowners choose inside mount shades in most rooms, but opt for outside mount in:

• Bedrooms (for blackout and privacy)

• Media rooms

• French or patio doors

• Windows with shallow depth or obstructions
