The wingless sash version of the Classica series allows the production of frameless shutters suitable for all historic buildings where this specific technical and aesthetic solution is required.. In this case, the hinges are fixed directly to the wall. Similar to the framed version, the possibility of integrating different types of slats, both fixed and adjustable, gives the system its flexibility whilst also ensuring control over the desired lighting level. These are achieved withouth neglecting aspects related to the safety and privacy of the homes.
