A cover for closing an access opening that leads to an infrequently used space within a building, such as an attic, that generally provides an air seal, thermal insulation and/or acoustic insulation at the access opening. The cover may be in one or two portions, including a closure alone or a closure and a frame having an aperture that can be closed by engagement between the closure and the frame. When the cover is used alone it engages a frame or a wall circumscribing the access opening. The cover is sized and shaped to close a stairwell, or the opening at one end of a stairway, an opening in a generally vertical wall, a hatch, or a pull down ladder. The closure and frame are each made of one or more components.

The present invention relates generally to a universal strut for doors and window elements. More particularly, the invention encompasses a universal strut that mates with a first formed member, and a second formed member, and which assembly is used as windows, doors, window frames, and door frames. The invention also provides a method of using the inventive universal strut for applications that require different widths and lengths for a production or customized window, door, window frame, or door frame. The universal strut can also be used as a thermal barrier between the first formed member, and the second formed member. Preferably, the universal strut is made from a non-metallic or thermal barrier material, while the first formed substrate, and the second formed substrate are preferably made from a metallic material. The universal strut allows for the formation of various configurations for the shapes of window and/or door elements.

A modular window assembly including a base frame, an interior frame cover, and an exterior frame cover. The base frame has a first complementary fastener located on an exterior face and a second complementary fastener located on an interior face. Each of the interior and exterior frame covers have a complementary fastener configured to releasably mate with the first and second complementary fasteners of the interior face and exterior face, respectively.

A door-and-window system having a handle component (121), a transmission component (123) and a force receiving portion (12231). When the handle component (121) is operated, the force receiving portion (12231) moves along a first guide groove (12211) via the transmission component (123), and at the same time a driving portion (12232) moves along a second guide groove (12221). Due to a relationship between a guide member (1224) and a third guide groove (12212), a first base seat (1221) translates relative to a second base seat (1222) along a direction of the third guide groove (12212), such that a movable door-and-window (11) can abut tightly against or move away from a sealing member (24) on a door-and-window mounting profile (2).

A method of assembling a window includes positioning an insulating material in a frame thermal break defined by a middle portion of a frame intermediate a first side and a second side of the window. The method also includes connecting a cladding to the frame. The frame includes a first material visible on the first side of the window. The cladding includes a second material visible on the second side of the window. The method also includes connecting a first glass pane to a second glass pane to form an insulated glass unit and positioning the insulated glass unit in the frame. The method further includes aligning the frame thermal break and a pocket of the insulated glass unit such that a central plane of the pocket extends through a middle portion of the frame thermal break. The frame thermal break and the pocket define a continuous thermal break extending through the window.
