A frame assembly for windows and doors includes a pair of side members and a pair of generally parallel cross members, each extending along a unique member axis. The cross members include a first frame portion and a second frame portion that extend generally along the member axis and are connected by a camming fastener that draws together and secures the first and second frame portions. A method of fabricating a shutter assembly includes forming a pair of C-shaped partial-frames, each from a side member coupled to portions of two cross-members. The method includes co-axially aligning corresponding portions of the two cross-members along two axes and joining the two C-shaped partial-frames with camming fasteners.

A door assembly comprises a rectangular door frame that has a first, second, third, and fourth frame member. The first frame member has an outer surface that has a first pair of parallel slots. A first parallel flange protrudes from and perpendicular to the outer surface between the parallel slots. A vane extends from the first frame member to the second frame member between the third and fourth frame members. The vane has a first end that includes a pair of parallel flanges fitted into the parallel slots such that a rear surface of the first planar flange is arranged between rear edges of the first parallel flanges. A bar is mounted to the rear surface of the first planar flange and configured to hold the rear edges of the first parallel flanges in substantially the same plane as the rear surface of the first planar flange.

The invention relates to a blade of a brise-soleil device, said blade being noteworthy in that it is produced in one piece comprising: substantially planar elongate, separate and parallel solid lamellae, discontinuous cutouts separating the solid lamellae, connecting spacers providing connection and spacing between solid lamellae, said cutouts being enclosed by the edges of the lamellae and the edges of the connecting spacers. The invention also relates to a method and a device for manufacturing such a blade.

A purification window embedded with a ventilation system, including: a window frame, and a double-layered glass window unit arranged in the window frame. An outdoor window screen roll and an indoor window screen roll are arranged at a left stile and a right stile, respectively. An upper middle position and a lower middle position of the double-layered glass window unit are respectively in rotational connection with a top rail via an upper shaft and a bottom rail via a lower shaft. The ventilation system includes: an air supply chamber and an exhaust chamber, both of which provided therein with T-shaped air dampers and fans. Both external edges of the outdoor window screen roll and the indoor window screen roll are provided with magnetic tapes configured for fixation connection with the upper shaft and the lower shaft.
