Avette offers roller shades that can be mounted either on the window frame or outside of it, depending on the preferences of the customer. The models suitable for installation on the window frame utilize a roller with an 18mm diameter; they can be mounted both on the openable and non-openable section, with or without a sidewinder mechanism. The shades installed on a ceiling or a wall can be manufactured with a 32mm, 38mm, 47mm or 65mm roller depending on the size and weight of the fabric. Roller shades with an 18mm, 32mm or 38mm roller are operated with a PVC chain or a metal chain, while the shades with a larger roller can be motorized.
