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.

A frame with segments that are in flush with each other is disclosed. The frame of the present invention comprises a plurality of segments, a plurality of outer retaining units and a plurality of inner retaining units. The segments are connected together to form a frame. Each outer retaining unit is disposed on the rear outer side of the juncture of each pair of neighboring segments. Each inner retaining unit is disposed on the rear inner side of the juncture of each pair of neighboring segments. In this manner, each pair of neighboring segments may be tightly joined together and the segments of the frame may be in flush with each other.

In the roof window (1), each sash member (31, 32) comprises a profile element (31a, 32a), an inner element (32c) and an intermediate element (31b, 32b) forming a connection between the profile element and the inner element of each sash member in an assembled condition of the sash (3). The profile elements (31a, 32a) of the sash members (31, 32) are located along respective exterior edge portions of the pane (4) in the assembled condition of the sash (3), and the profile elements (31a, 32a) of the top sash member (31) and the two side sash members (32) are formed as a set of longitudinal profiles of substantially uniform cross-section.

A frame assembly, for use in window and door applications configured to retain a panel, comprising a frame with a cover assembly and a support assembly having a track assembly, and a sill assembly and a header assembly both interconnected to a securing surface. The cover assembly is interconnected to the support assembly. The sill assembly comprises a roller member disposed in supporting relation to the track assembly, and the header assembly is disposed in supporting relation to the support assembly so that the frame is movable relative to both the header assembly and the sill assembly. At least a portion of the frame comprises a predetermined thickness and a predetermined width. The predetermined thickness is substantially less than the predetermined width so that both cooperatively and concurrently enhance viewing through the panel and the frame's stability.

Window lite assemblies and methods for installing the assemblies are provided herein. The assemblies described herein are configured to be installed in new and existing buildings, especially in building corners, while leaving some or all of the horizontal structural members such as headers and sills in place.
