How to Block Light From The Sides of Blinds
Light sneaking in from the sides of blinds can be frustrating, especially if you're trying to sleep, watch a movie, or create a fully dark and cozy room. Even high-quality blinds can have small gaps where light enters, affecting privacy and comfort. Fortunately, there are several effective ways to block side light and improve room darkening without replacing your blinds in Dubai. In this guide, you will learn practical methods, installation tips, and smart solutions to stop light leakage and achieve a darker, more peaceful space indoors.
Understanding Light Leakage Around Window Treatments
Light leakage around window treatments is a common issue that can disrupt the ambiance of a room. This occurs when there are gaps between the blinds and the window frame, allowing unwanted light to seep through. Understanding the causes of these gaps is the first step in addressing the problem effectively.

Common Causes of Light Gaps
Light gaps can be caused by several factors, including improper installation, the natural warping of materials over time, or simply the design of the blinds themselves. For instance, inside-mounted blinds often leave a small gap on each side, which can let in light.
