Light Filtering Window Treatments

Light filtering window treatments are window treatments that are designed not to block out light, but instead to filter out the harshest UV rays and glare for spaces where preserving the view is essential. Unlike room darkening window treatments, light filtering window treatments will not make a room much darker. Depending on the opacity of the treatment, the room may be dimmer, but the primary intention of these shades is to preserve one’s view of the outdoors.

Silhouette® Sheer Shades are one fantastic example of light filtering window treatments. Their stunning, sheer fabrics diffuse harsh light into a warm glow. With varying opacities, you can have shades that filter out just enough light to maintain your perfect view, or thicker fabrics that help keep a room cool and comfortable even in the most intense Florida sun.

Room Darkening Window Treatments

Room darkening window treatments are more self-explanatory than light filtering window treatments; room darkening window treatments are designed to block out large amounts of light to ensure that a room is dark, even with direct sunlight. They accomplish this with thick fabrics or specially designed liners that prevent even the slightest bit of the sun from leaking through.

There are many different options for room darkening window treatments, including Hunter Douglas Roman Shades and Cellular Shades, each offering its own unique styles and functions alongside the option of adding a room darkening liner.

Room Darkening window treatments are an excellent option for nurseries, living rooms, bedrooms, or any space where you want complete control over the light entering the room. These window treatments can ensure a great night's sleep or a movie-theater experience, even during the brightest parts of the day.
