A self-locking handrail system includes a female profile and a male profile. The female profile includes a first leg, a first locking extension that is approximately parallel to the first leg, having a gap formed therebetween, and a first vertical leg extending from the first locking extension approximately orthogonal to the first locking extension. The male profile includes a second vertical leg, and a second locking extension extending from a free end of the second locking extension, forming a fulcrum. A panel is positioned between the first vertical leg and the second vertical leg. A bar is positioned between the panel and the second vertical leg, the bar having first and second surfaces opposite one another that are not parallel with one another, causing the female and male profiles to engage by tilting the second vertical leg outward from the panel and about the fulcrum.

A window having a window frame, a leaf frame nested in the frame, the leaf frame framing a double-glass pane; a reservoir entirely disposed in a horizontal element of the leaf frame of the double-glass pane, the reservoir being filled with a tinting substance; horizontal axes disposed at midpoints of a height of vertical elements of the leaf frame, the horizontal axes serving to couple the leaf frame with the window frame; the leaf frame being configured to rotate about said horizontal axes by 180 relative to the window frame to cause the tinting substance to move by gravity from the reservoir into the double-glass pane, wherein a capacity of the reservoir is hermetically coupled to an internal capacity of the double-glass pane. The tinting substance is liquid or solid homogeneous powdery mass consisting of spherical crumbs.

A self-locking glazing system includes a female profile having a first locking extension and a first leg extending therefrom, the first leg having a first tip. The system includes a male profile having a second locking extension and a second leg extending therefrom, the second leg having a second tip that is approximately opposite the first tip, and a thermal break material positioned between the female and male profiles. When a panel is positioned between the first and second tips, the female profile and the male profile are caused to engage against the thermal break material.

A building component includes an insulated glass unit including a first glass pane and a second glass pane defining a pocket therebetween, and a frame supporting the insulated glass unit. A central plane extends through the pocket and is spaced equal distances from the first glass pane and the second glass pane. The building component further includes an insulating material in the middle portion of the frame. The insulating material defines a continuous frame thermal break circumscribing the insulated glass unit and extending through the frame. The central plane extends through a center of the frame thermal break and forms a common central plane of the building component with substantially equal portions of the frame thermal break extending on each side of the common central plane when the building component is in a closed position.
