The best window coverings for sliding doors are the ones that block out the most light. For instance, blinds made of wood or bamboo typically do not keep out as much sun and heat as curtains with vertical pleats.
The most common type of blind used with a sliding door is the vertical blind, which goes in front of the door when it’s closed. These are perfect for larger spaces because they cover a lot of space but block out less light than other types of window treatments. There are also mini-blinds and horizontal shades, which offer more privacy and won’t obstruct your view so much when looking outside your window!
