A twin louver bank window assembly for efficient thermal control, the assembly including an assembly surround frame including a head member, a sill member and at least a pair of opposed side channel members and a pair of louver banks mounted relative to the assembly surround frame, each louver bank including a number of louvers, one louver bank located towards an outer side of the assembly surround frame and one louver bank located toward an inner side of the assembly surround frame.

A motorized and automated shutter with slip clutch provides automated control of positioning of the louvers while allowing manual movement of the louvers without damage to the drive train and without disrupting automated control. A slip clutch assembly in the motorized drive train allows manual movement of the louvers of the shutter without imparting force back into the drive motor. A position sensor monitors the position of the louver and provides a signal to control circuitry to allow synchronization or simultaneous operation of multiple window shutters based on manual movement of a single louver.

A shutter including a frame, a first blade set, a second blade set, a power source and a blade driving system is provided. The frame has a frame body. The first blade set and the second blade set are disposed on the frame body of the frame. The power source is disposed in the frame body. The blade driving system connects the power source, the first blade set and the second blade set for rotating the first blade set and/or the second blade set to rotate.

An installation for covering and uncovering a surface includes a series of slats of adjustable inclination supported by pivot pins via a set having a first carriage and a second carriage. A movement system has, for each head slat, movement motors on board the first and second carriages. For the even-numbered slats, firstly a retractable coupling (A) is fastened between the first carriage of said slat and the first carriage belonging to the head slat or to the neighboring slat of lower number, and secondly a drive system (S) is provided for driving the second carriage of said slat in translation. For each odd-numbered slat that is present, a retractable coupling (A) is fastened between the second carriage of said slat and the second carriage belonging to the neighboring slat of lower number, and a drive system (S) is provided for driving the first carriage of said slat in translation.

Adjustable plantation shutters and methods for forming and installing the same. A shutter includes a frame that includes a base portion with a hub and an arch portion coupled to the base portion. The shutter further includes a plurality of louvers extending from the hub toward the arch portion, each louver including a pivot axis. The shutter is configured to selectively transition between a closed orientation and an open orientation by rotating each louver about the pivot axis. In some embodiments, each louver is operatively coupled to the arch portion via a magnetic coupling. In some embodiments, each louver is coupled to the hub via a corresponding drive pin, and the shutter further includes a drive mechanism operatively coupled to each louver to pivot each louver about the respective pivot axis.
