Outside Mounted Blinds & Shades Block Out More Light and Provide Full Coverage. Since outside mounted blinds and shades cover more of the window and frame than inside mount blinds, they provide more light coverage.
Why fit outside of the recess? The main advantages of hanging your blinds outside of the recess are that more light will enter the room when the blinds are open. You can block out more light when the blinds are closed. However, any items that you have placed on the windowsill won't be visible when you close the blinds.
As opposed to inside mount when the coverings are mounted inside the window frame, outside mount is mounted on the wall above the window and directly on the trim. Because of this the blinds or shades will need to be wider than your window opening.
Inside mounts are the most popular choice. They offer a clean, finished look because the blinds or shades are recessed and contained inside the window casing. Inside-mounted window treatments are NOT the best choice for you if: Your window frame is not deep.
For maximum privacy, mount the blinds above the window frame and extend them past the sides and bottom of the frame. Light bleed around the blinds is decreased with the extra width and length. If necessary, shim the blind bracket out so the blind falls freely. This method works well for disguising an ugly window frame.
Attaching Brackets:For outside mount, the brackets should be placed on the face of the window outline on the two sides of the window. And for inside mount, the brackets should be put up against the inside top corner of each side window.
Use a tape measure and a pencil to mark 1 1/4 inches away from the window to keep the blinds from touching the glass when hung.
An inside mount simply means that the window covering fits neatly inside the window, outlining crisply the inside of the window frame and snugly fitting all around the inside. An inside mount offers the cleanest and most minimal look and can be installed as deep or as shallow as you desire.
Not Adding Width To Outside Mount Blinds
We recommend going at least 2" wider than the opening on either side, so 4" total. For the height, go about 3 inches above the window trim (to allow for the mounting brackets) and measure from that point down to the window sill.
Roman shades can be installed both inside and outside the window frame depending upon your need and the depth of your windows. Structurally we believe that soft fold and dog-ear Roman shade would make a better fit as outside mount than the inside mount.
Inside mount refers to blinds and shades that are installed within the confines of a window frame. That means the headrail is attached flush with the top of the window frame and the window treatment is fully contained inside the four corners of the frame itself. Pros: Inside mounts provide a sleek, built-in appearance.
Outside mount (sometimes referred to as outside brackets) means that a blind or shade is installed outside of the window frame while an inside mount is installed inside the window opening. Inside mount blinds are often flush with the window's opening and do not cover up the trim.
Round off your measurements to the nearest 1/8 inch. As a rule, the blinds will look nice if they extend about 3 inches beyond each side of the window opening. So a 42-inch-wide window calls for a 48-inch-wide blind that allows for a 3-inch overlap on each side.
An over rolled blind on the face will leave a gap between the blind and the architrave, allowing a large amount of light to come in from the sides. An under rolled blind on the face however will roll as close to flush against the architrave/wall, minimising light and increasing privacy.
A recess measurement of your window is the measurement of the opening inside of it. The reason for this measurement is that a recess blind will fit into the opening of your window; it won't overlap the walls on either side of it.
Window should have a minimum recessed space of 2 3/8" for inside mount. Measure the width of the window from the top of the opening to the sill in 3 places. Use the smallest dimension for the blind width. The factory will automatically deduct up to 1/4" - 1/2".
Should blinds rest on the windowsill? Yes, for your blinds to work to greatest effect and to achieve the right visual finish, window blinds should rest on the windowsill.
The actual width of the 35" blinds are 34.5" (half inch narrower) to comfortably fit inside a 35" opening. So if your frame is exactly 34.5 inches, I would go with the 35" blinds.
Minimum inside mount depth is the amount of depth required to securely mount the shade/blind inside the window frame. The minimum flush mount depth is the required mount depth needed for the shade/blind to fit fully inside of the window frame, without protruding outward at all.
Flush Inside Mount means the entire shade fits within the window frame. In other words, if you were to run your hand along the wall or window frame, your hand would not bump into the shade. The minimum window frame depth required for a flush mount is 2 1/4″.
Blinds can either be installed inside the window frame (for inside-mount blinds) or on the wall on either side of the window (for outside-mount blinds).
When you specify inside mount, we will make a size deduction to allow for operating clearance. We will deduct up to 1/4″ from each side (on vertical blinds there is also a height deduction of 1/4″). The deductions are made so that the blind will not rub or scratch your window frame.
If you can't find blinds wide enough to cover large windows, you can hang two sets of blinds in one window to create nearly seamless window coverage. An inside mount tends to work better when hanging two sets of blinds. It looks cleaner, and you can hide the two rails behind a blind valance.
Measure both the width of the window and the height of the window. Consider adding an extra 3 inches to the width and height for optimum light control and privacy. Extending the blinds outside the window will also provide the space needed for the mounts and help the window appear larger than it actually is.
