A high speed sliding roll-up door interposed between two rooms at different temperatures has a flexible curtain to close or open a passage of a wall separating these rooms. The roll-up door has two side uprights having guide rails of the side edges of the curtain, and an upper crosspiece near which there is a storage area of the curtain. A device for draining the condensation water present on the curtain includes guide rails having an upper rectilinear portion, close to the shelter area, and a lower rectilinear portion offset with respect to the upper rectilinear portion, between which an inclined portion is interposed which is connected upstream and downstream with the upper and lower rectilinear portion. Below the upper rectilinear portion there is a gutter formation configured to receive the condensation water present on the curtain, when this rises towards the shelter area.

A lift rail and sill assembly for a window frame assembly includes a lift rail defining a lower rail end and an upper rail end, the lift rail further defining a seal retaining channel, the lift rail movable between an open position and a closed position; a seal received in the seal retaining channel of the lift rail; and a sill defining a lower sill end and an upper sill end, the sill comprising a sill ledge arranged at the lower sill end and a sill flange extending from the sill ledge to the upper sill end; wherein a gap is defined between the sill ledge and the lower rail end of the lift rail in the closed position to allow fluid to flow between the sill ledge and the lower rail end, and wherein the seal engages the sill flange in the closed position.

Apparatus allowing ventilation through a ventilation shaft to an underground ventilation duct fluidly communicating through the ventilation shaft to an atmospheric opening of the shaft and on threat of flooding operable to prevent downward flow of surface water into the underground ventilation duct includes support sidewalls fitting in the shaft providing a ventilation passage between support top and bottom openings and a suspension member supported on opposed lateral sidewalls unobstructively horizontally spanning the passage proximate the top opening and holding one or more hinge connected panels in the passage that manually release to rotationally close the passage and prevent flooding and are manually rotationally liftable to a home position allowing ventilation. The suspension member is liftingly removable from the support and may include end keys received in keyed supports to allow the suspension member to fit in the supports so a specific panel closes to a specific sidewall.

A frame assembly for installation into a door or window casing is provided. The casing has a top and two side studs. The assembly includes a head jamb, a pair of side jambs, and a pair of connecting mechanism. The head jamb is removably securable to the top stud. Each side jamb is removably securable to a respective one of the two side studs. Each connecting mechanism for connecting a respective one of the side jambs with a corresponding end of the head jamb includes a first component and a second component. The first component is provided on the head jamb, and the second component is provided on the side jambs. The first and second components are removably engageable, and allow the frame assembly to be installed and uninstalled from the door or window casing. A method for removably installing the frame assembly is also provided.

A window assembly for installing in a window framing (also referred to as a “window casing”) of a wall of a building. The window assembly is configured to have a frameless appearance when installed with the finish surround installed around the interior and/or exterior of the window. The window assembly also allows the glass panel to be removed with a minimum of removal of the finish surround, such as without removing any of the finish surround, or only removing the finish surround around several sides of the only one of the interior or exterior of the window. For example, in most cases, only the interior finish surround around the right side and left side of the installed window frame needs to be removed to remove and replace the glass panel. Furthermore, the window assembly includes an integrated drain for draining moisture which leaks into the window assembly.

A weep sill assembly includes an elongated sill base, a first floor within the sill base, and a drain conduit. The elongated sill base includes a top opening configured for fluid ingress. The first floor divides an interior of the sill base into an upper chamber and a lower chamber, wherein the floor includes a first aperture that provides fluid communication between the upper chamber and the lower chamber. The drain conduit is in fluid communication with the lower chamber. In another aspect, a sliding door assembly includes a header configured for attachment to a wall, a weep sill assembly, and a door panel configured for slidable engagement with the header and with the weep sill assembly.

Door jamb and sill assemblies are provided. In one aspect, a door jamb weatherstripping assembly includes a weatherstrip member and a retaining member. The retaining member is elongated and is affixed along a length of the door jamb. The retaining member defines a retaining channel for retaining an anchor portion of the weatherstrip member, and a door seal being configured to sealingly contact the face of the door parallely to a weatherstrip portion of the weatherstrip member when the door is closed. According to another aspect, an elongated cap may be secured to the retaining member in a spaced-apart arrangement to jointly form a shielding chamber along an outer portion of the jamb. In another aspect, a door sill assembly having a U-shaped body engaging the bottom edge of the door is provided. The door sill assembly may include side channel seals and bottom channel seals.
