Installing and using blinds will allow you to choose complete light blocking, or partial shading depending on your preferences and outdoor conditions. You can adjust two main types of blinds. Roller blinds: Regular stages or light-light stages with electric or manual opening, allowing control of the amount of light and air in your home and providing an additional layer of security and protection from wind. Louver blinds: Stages that allow manual opening and control of the amount of light in the home.
