An assembly for a door or window frame including an elongated sill and a corner key attached to each end of the sill. The corner key includes a water chamber for collecting water therein and a plurality of ports for diverting water from the water chamber outwardly through a drain port. The water chamber and plurality of ports are designed to temper a high-pressure gradient in the sill and effectively promote water egress away from the sill.

A door includes a first skin, a second skin, two stiles, a core, and a gas permeable membrane. The first skin provides a first outer door surface. The second skin provides a second outer door surface. The two stiles are disposed at least partially between the first skin and the second skin. At least one stile defines a vent therein. The core comprises a foam material and is disposed between the first skin and the second skin. The gas permeable membrane, which is permeable to gas but not to the precursors of a foam material, is disposed on the at least one stile covering the vent. The gas permeable membrane contacts the foam material in the core, and separate the foam material in the core from the vent.

A security unit protects a glazing unit supported by a window frame The window frame defines a void that is in communication with an air space through external air vents. The window frame has a side panel that defines side panel holes. The security unit includes a security panel that is spaced apart from the glazing unit to define an air cavity and is secured to a vertical tubular bar that is secured to a side panel of the window frame. The vertical tubular bar defines a passage therethrough in communication with the air cavity through air cavity vents and defines passage holes aligned the side panel holes. Air circulates from the air cavity to the air space through the air cavity vents, the passage holes, the side panel holes and external air vents.

An intelligent window allowing ventilation has an outer frame, a sliding frame, an upper locking rod, a lower locking rod, a driving module, a power supply module, and a switch assembly. The sliding frame is slidably mounted in the outer frame. The switch assembly controls the driving module to selectively drive the upper locking rod and the lower locking rod to two locking positions respectively, two ventilation positions respectively or two unlocking positions respectively. Since no handle is needed, an appearance of the intelligent window is neat and scenery outside the intelligent window would not be sheltered. In addition, by actuating the switch module to electrically drive the upper locking rod and the lower locking rod, a user is able to switch the intelligent window to a locked state, a ventilation state or a unlocked state. It is labor-saving and simple in operation.
