Blocking Light from the Sides of Blinds or Shades

While natural light streaming into your home offers a whole host of benefits, including boosting your mood or helping you be more productive, at times, too much light can be disruptive or distracting.

For instance, light sneaking in around the sides of blinds or shades first thing in the morning can keep you from catching a few extra winks, while the glare on your TV screen from evening rays can dampen that movie theater feeling.

The spaces that let in this extra light are called light gaps. They’re common to all blinds or shades that are mounted on the inside of window frames, and are needed in order for the blinds or shades to operate smoothly. If the blinds or shades were mounted tightly against the frame, their edges would rub on it when raised or lowered, damaging them.

You don’t need to live with light gaps, though. Consider these solutions for keeping unwanted light at bay.

Layer Up with Side Panels

Pairing stationary side panels with blinds or shades is another option for blinds or shades already adorning your windows—and one that adds depth and dimension to a room.

Of course, side panels are also an option if you’re considering new window treatments and want to avoid light gaps from the start. If that’s the case, look to our Design Studio™ family of side panels and drapery, which are designed to layer and coordinate with all Hunter Douglas window treatments.

The exclusive fabrics in our Design Studio collection include luxe basics, lofty textures, alluring jacquards, artisanal embroideries and luminous sheers. Fully lined with a light-filtering or room-darkening liner (except for sheers), side panels are available in multiple styles.

Mount Your Shade Outside the Window

If you’re planning on investing in new blinds or shades, you might want to think about mounting them on, outside or above the window frame.   

When you lower a blind or shade that’s mounted outside rather than inside the window frame, it will fully overlap the window, helping to block light gaps between the window’s outer edges and the window frame. (Keep in mind that you might still get a little glow, but you won’t get as much light sneaking through as you would with an inside mounted window treatment.)

Other benefits of mounting blinds or shades above the windows include making the windows (and the room) feel taller, and an unobstructed view when you fully raise the blinds or shades.
