Unlike a normal window, roof windows or skylights require special blinds with attachments such as side wires or rails to secure them in place and allow them to move at the same time, so that they don’t fall vertically. Also, unlike normal windows, roof windows pivot at the middle while open, making it impossible for a normal blind to be mounted on their outer frame. To be allowed to open at your will, a roof window blind needs to sit inside its opening sash. The comforting truth is that there are varieties of roof window blinds that serve different specific purposes. Here’s a look at each of them. Blackout blinds, the most popular type, are flat and shut out traffic noise, some heat and all daylight. They’re made to fit inside the aluminum side rails’ internal frame. Avoid plastic side rails as they’d warp over time. Pleated or plisse blinds are folded into pleats running on a wire mounted within the roof window. Being less sturdy than blackout blinds, these are ideal for regular use. Roller roof blinds are the cheapest option, and stay tight inside the roof window frame. Venetian blinds are the most attractive ones and come in several styles and designs. They allow you to position the blind, yet still manipulate the slat angle, providing great flexibility in the amount of light that enters your room.
