Light Leaking or Bleeding Into The Room With Roller Shades
What does it look like?
Light leakage can happen in multiple ways! We often get asked how to prevent or how to lessen/fix light leakage through the window into the room. Paying attention to small details before specifying your drapes can have a big impact on blocking most of the light.
Explore some problems, reasons and recommendations in this post.
THE PROBLEM Visible light between metal and room surface (sheetrock, sill, etc.).
THE REASON If there is a crack, light will expose it! Any solid metal surface will highlight wall or sill imperfections.
OUR RECOMMENDATION Have general contractor float or caulk imperfections or design treatment to include soft drapery framing window.
THE PROBLEM Light leaking through the space between side channel and fascia.
THE REASON These are two independent pieces that must remain separate for the shade to function. Light will always appear below the fascia/above side channel.
OUR RECOMMENDATION Adjust expectations, this light gap is not avoidable, use additional top treatment, or side panels if intolerable.
THE PROBLEM “L” channels do not provide the same light fastness as “U” channels.
THE REASON “L” channel is not intended to surround the shade completely so light will escape by design.
OUR RECOMMENDATION Understand the flexibility and forgiveness of “L” channel comes with some trade-offs, one of which is additional light leakage. To improve light blocking, “U” channels would be recommended.
THE PROBLEM Shade bands will require 1/4”-1/2” of light gaps at all sides, due to bracket, clutch and hem bar clearance requirements.
THE REASON An inside mounted treatment requires fabric deductions for shades to traverse on componentry.
OUR RECOMMENDATION If metal side or sill channels are not utilized to block this light, other drapery treatments will be required to provide light fastness, or change to outside mount.
