Key takeaways
- Inside mounts look clean and sit within the frame.
- Outside mounts cover more and block light better.
- Shallow frames often need outside mounts.
- We check each window before recommending one.
Inside mount
An inside mount fits within the window frame, showing the trim around it. It looks tailored and keeps the window clean. It needs enough frame depth for the headrail and may leave small gaps of light on the sides.
Outside mount
An outside mount sits on the wall or trim, overlapping the window. It covers the whole opening, reduces light leaks and can make a window look larger. It is the best choice for blackout and for shallow or uneven frames.
How we decide
We check frame depth, obstructions like cranks and handles and how you want the window to look. Sometimes a mix works: inside mount where it fits and outside mount where light control matters.

Quick answers
Do outside mounts look bad?
Not at all. A well-proportioned outside mount can look polished and built in, especially with a valance or cornice above.
Can I switch from inside to outside later?
Usually, but the product is made to size for its mount type, so it is easier to choose correctly the first time.
