Inside or Outside Mount Blinds: Choosing the Best Option for Your Windows

When purchasing window treatments, an important decision arises regarding the mounting style. Buyers must choose between inside mount and outside mount, each with distinct features and appropriate applications. Understanding these options is crucial for ensuring the right fit and appearance in any space.

Selecting the correct mount can significantly influence the aesthetics and functionality of window treatments. This article provides insight into both styles, helping readers determine which option best suits their needs before taking measurements or placing an order.

Choosing Between Inside Mount and Outside Mount for Blinds

When selecting the type of mount for window treatments, the depth of the window frame is the primary consideration. An inside mount is generally preferred if there is sufficient depth available, providing a clean and streamlined appearance. Conversely, an outside mount may be necessary for windows lacking sufficient depth or when there are obstructions like cranks or handles.

Measurement Steps

1. Assess Depth: Begin by measuring the unobstructed depth of the window frame. This should be done free of any obstructions that may interfere with installation.
   
2. Identify Obstructions: Look for any items such as cranks, handles, alarm sensors, or decorative trim that intrude into the window space. These will impact the available depth.
   
3. Specific Measurements: Measure from the point where these obstructions end to the edge of the window casing or drywall. For double-hung windows, ensure to measure from the farthest jutting pane to the edge of the trim.
   
   

Before ordering, check the specifications of the chosen blinds or shades to confirm they will fit appropriately. For situations involving tile that extends into the window space, consulting a designer for customized options is advisable.

What is an Inside Mount?

An inside mount refers to the installation of blinds or shades directly within the window frame. This method fixes the mounting brackets either to the top (the “ceiling” of the window opening) or the sides of the frame.

Opting for an inside mount creates a polished appearance, ensuring that the window treatments align closely with the trim or wall. This approach also preserves any decorative molding, providing a seamless integration into the window design.

When to Choose Inside Mount Blinds

For the majority of customers, an inside mount is the recommended choice, suitable for approximately 95% of cases. However, individuals should consider window depth or potential obstructions, which may restrict this option. Typically, a few inches of recess are necessary to properly mount the brackets. It is advisable to consult the specifications for the specific product to determine the required depth, including minimum and fully recessed measurements.

If the window has only the minimum depth, the window treatment can still be installed, though the headrail may extend slightly beyond the trim. In contrast, a fully recessed depth allows for proper placement of the blinds, ensuring that the headrail remains flush with the wall or trim.

Measuring for Inside Mount Blinds

For those interested in an inside mount, precise measurements of the window opening from edge to edge are essential and should align with the guidelines for the chosen treatment. It is important not to reduce the window opening size when ordering, as deductions will be handled at the factory to prevent any issues with operation.

Professional measurement and installation services are also an option for those who prefer assistance.

Understanding Outside Mount Installations

An outside mount refers to the installation of blinds or shades on the wall above a window or directly onto the window trim. This style requires the window treatments to be larger than the actual window opening, ensuring comprehensive coverage. Opting for an outside mount is beneficial when the window frame lacks sufficient depth to accommodate inside mounts or when increased light blockage is desired.

When to Choose an Outside Mount

An outside mount is particularly advantageous in situations where:

• Shallow Window Frames: If the frames are too narrow for the necessary mounting hardware.
• Obstructions Present: Factors such as window cranks, security sensors, or decorative trim may hinder the full descent of shades or blinds.

Customers often prefer this mounting option to eliminate light gaps commonly found with inside-mounted products. Larger blinds or shades fixed above the window enhance darkness within spaces, making them ideal for areas like nurseries, bedrooms, or viewing rooms.

Additional Benefits of Outside Mounts

Beyond light blockage, outside mounts can serve additional purposes:

• Camouflage Unusual Window Shapes: They effectively disguise oddly shaped or misaligned windows.
• Enhance Visual Height: Mounting shades higher than the window can create the illusion of taller windows, a trick that could be complemented with layered draperies.
• Cover Unattractive Moldings: This installation method can hide window areas lacking decorative moldings or conceal moldings that do not align with one’s design preferences.

Measuring for Outside Mount Blinds

To achieve optimal coverage, outside-mounted window treatments should be approximately 2 inches larger than the window opening on all sides. It is essential to follow specific measuring guidelines to ensure accuracy. Unlike inside mounts, customers must provide precise dimensions for their blinds or shades, as there will be no deductions made by the manufacturer.

For those hesitant about measuring, professional measurement and installation services are available, offering peace of mind and expert guidance.

Combining Inside and Outside Mount Shades for a Layered Effect

Layering window treatments can enhance versatility. The base layer can be installed as an inside mount, while an outside mount can be added above. Options for the base layer include sheer roller shades or blackout shades for varied light control and aesthetic appeal. This approach maximizes both functionality and style.
