Aria and Terra are two chain operated models of interior blackout/shading roller blinds, part of Bettio Living range. Aria has a very small, 33 mm box while Terra has a 41 mm box that can house thicker fabrics and can be used for bigger openings. It is important to enhance that this line of products follows the chosen fabric thickness: at the end of the catalogue you will find a table showing the available sizes according to the fabric and relevant technical features. Also keep in mind that a small amount of light can filter through the side rails of the blackout blinds. The standard control is located on the right side, but you can request it on the left side. Although they are chain operated, they also have springs that keep the fabric stretched, ensuring a perfect finish: however, you can always stop the handle bar at the desired height, a very useful feature for shading fabrics. In case of insufficient room for recess installation, they can be frontally installed. Acqua and Sabbia are very aesthetical, with plastic parts that match the colour of the aluminium details and completely hidden screws.
