How to block lights from the side of the blinds

August 09, 2021

Blackout roller shades with lights filtering on the sides

Do you have lights coming from the side of your blinds and shades that you would like to cover? Well, don't fret because there are ways for covering up these pesky gaps between your shades and your wall. Whether you already have your window treatments or not, read on to find out what options we offer!

Window treatments are made a little bit smaller than the width of your window to ensure they don't rub and cut into each other when drawn up or down. This leaves just enough space on either side for light and heat from outside to filter inside!

Block the gap on the side of your existing blinds

At ShadeMonster, all window treatments are custom-made to fit your windows with precision. Depending on the type of shade chosen for a particular window, you will have different degrees of light gaps in between blinds shades and curtains – cellular shades for example, have as little as ¼” gap while roller blinds, solar shades, and sheer shades can be up to 1/2" from each side.

If you are looking to cover gaps on existing blinds or shades, there are 2 options available.

  • Side Channels or Side Track for blinds

The first option is to upgrade your window with vinyl light gap blockers to prevent unwanted sunlight from entering and blocking out the darkness. These are strips you can easily adhere to any surface, making it easy for them to stick securely on nearly anything!

This choise will give a clean and linear look to your window treatments and to the over all room, preventing all the lights from coming in. Most of ShadeMonster blackout shades offer light blocker as an upgrade, but if your shade does not offer them, you can purchase them separately.

  • Drapery layered with blackout shades

The Second option is to layer draperies on top of your blackout or roller shades which will give your windows an attractive layered look and the blackout drapes will keep it dark in any room when they're pulled shut at night – perfect for blocking out unwanted sunlight!

How to block light from windows with new window treatments

Did you know that different people have very different needs when it comes to blocking out light? Some cannot get enough darkness, while others would rather not be woken up too early in the morning by daylight.

If you are ordering new window treatments but want to prevent light gaps, first ask yourself how much sunlight your house receives and choose a material accordingly. For instance, blackout fabrics will block more than roller shades and roller shades may offer another solution for those who prefer some natural lighting during their waking hours - You could even layer them!

Outside Mount Blinds Block Gaps Lights

Blocking light gaps can be a pain, but there are some easier solutions. Window treatments such as blinds or shades come in many different types and often have options for blocking out the sun's rays completely with an outside mount blind.

Outside mount shades are mounted outside the window opening and made larger on all sides to cover the entire window. This will eliminate any chance of those pesky daylight shadows. If you're not looking to cover up decorative molding on either side of the window frame, then this is probably the best option for you- especially if privacy is your goal too, since these styles offer complete coverage.

While this may make it difficult to see out of your windows, these shades will go from bottom-to-top covering all areas inside or out so that no one sees anything but pure darkness!
