We offer two types of mounted systems:
Architrave mounted is where the screen framework is attached to the outside architrave or frame of your door or window.
Inner sill mounted is where the screen framework is attached to the window or door jamb (inside the frame of your door or window).
The two main considerations as to which style would suit your opening best is if there is enough room on your jamb to fit the inner sill system, and aesthetically which one you prefer.
