While a window with a trapezoidal or other custom shape can be a stunning addition to a building’s aesthetic, it can also create problems for solar control. Standard rectangular shades and blinds aren’t designed for this need. But we have a few solutions.

Here are five ways to provide solar control for odd-shaped windows.

Fixed Panels
The FlexShade® Panel is a non-operable fabric panel that’s perfect for hard-to-reach openings, including skylights, sloped glazing in solariums, and oddly-shaped openings. The panels can be used inside or outside the glazing and attach with removeable mounting clips, so you can maintain and clean them.

Rack Arm Systems
Draper’s FlexLouver Rack Arm System is a non-retractable louver system that can be installed on vertical, horizontal, or inclined glazing. This system can shade almost any shape of glazing, including circles, squares, triangles, trapezoids, and more.

Adjustable slat angles prevent direct sun penetration, whatever the sun angle. Precise light control can be achieved with slow tilting of slats.

The FlexLouver is designed for interior or exterior use, depending on the slat selection.

Custom-Shaped Shades
Sometimes the customer doesn’t want the shading solution to be visible all the time. They want the ability to retract the system during certain times of day.

Custom-shaped shades can work in some oddly-shaped windows, such as squares, trapezoids, or extremely tall, narrow openings. To see if a particular window can accommodate a retractable shade, our shade design team needs an accurate drawing with exact dimensions, slopes, or angles.

Outside Mounted Shades
Instead of making the solar control solution conform to the shape of the window, simply mount it to the wall or ceiling instead of inside the opening. The shade will be built to cover the window at its widest point, and when deployed, it will extend to both sides of the window.

While this is a simple solution, it does require space on each side of the window. This is not an option if there are any obstacles the shade might encounter while in motion.

Custom Louver Systems
For glazing that covers a large area or has a custom shape or angles, a pre-existing product won’t help. A completely custom louver system may be required.

Our solar control solutions team will work with you through drawings, 3D prints, and full mockups to develop the perfect custom solution. Whether we design and build your solution in-house or use our relationships with global partners and our own Draper family of companies, our dedicated custom solutions team has the project management experience to guide you through the entire process—from concept to sign-off.
