A seal assembly for an upward acting door that is positionable between an open and closed position. The seal assembly contains a base member having a first and second flexible sealing member extending therefrom for sealing engagement with the door. The base member is mounted adjacent the door to facilitate sliding engagement between the door and the first and second seal members as the door is moved between the open and closed positions.

A roll-up door including a flexible curtain having a front surface, a back surface, a first end coupled to a shaft, a second end opposite the first end, and first and second side edges extending between the first end and the second end, the flexible curtain being moveable between a retracted position wherein the flexible curtain is coiled around the shaft and a deployed position wherein the flexible curtain is uncoiled from the shaft. A first retention band is mounted along at least a portion of the first side edge of the flexible curtain, the first retention band including an inner surface at least partially facing towards the flexible curtain, an outer surface opposite the inner surface, a fixed edge attached to the flexible curtain generally parallel to the first side edge, and a free edge opposite the fixed edge and movable relative to the fixed edge.

A roller shutter includes a chamber with an opening, a roller curtain movable between being fully contained within the chamber and extended beyond the chamber through the opening, and at least one guide rail along and relative to which said roller curtain is movable between being retracted and extended, wherein the roller curtain includes a plurality of slat members interlocked with each other for relative pivotal movement, the plurality of slat members collectively forming first and second major surfaces, and a first layer of fire-resistant and/or heat-resistant fabric fixedly mounted to the first major surface of the slat members and a second layer of fire-resistant and/or heat-resistant fabric fixedly mounted to the second major surface of the slat members, and wherein the guide rail includes at least a first sealing member which, when the roller curtain is extended, contacts or presses into the first layer of fire-resistant and/or heat-resistant fabric.

A quick-action roll-up door includes a flexible door leaf (6) with a vertical running direction for closing a door opening bordered by a door frame (1). The quick-action roll-up door includes a drive (7) for the opening and closing of the door and a pressing fixture, with which the door leaf in a door leaf closed position can be pressed against the door frame (1).

A retractable screen device for a framed opening employing a frame track fastened to each side support of the framed opening; the frame track forming a compartment for receipt of a guide rail with a decompression gasket positioned between the frame track and the guide rail. A screen mounted on a horizontally disposed rotatable shaft secured to a header of the opening has laterally opposed side edges with an elongated flexible protrusion secured along the length of each side edge. The guide rail receives and guides the screen protrusion along a longitudinal direction, and the decompression gasket allows the guide rail to traverse the frame track side walls to permit the screen to flex while maintaining a consistent tension on the screen. Vertical tension adjustment is provided by use of a biasing member coupled to the center axle that activates when the screen is deployed.

The invention relates to a door comprising a door leaf (10) which can be moved between an open position and a closed position and a guide arrangement for guiding the movement of the door leaf along a predefined path between the open position in the closed position, wherein the guide arrangement has at least one guide web (100) which is arranged fixedly with respect to a wall opening, extends at least along a portion of the predetermined path, and has two outer boundary surfaces (102, 104) and at least two guide devices (32, 34) which are fastened to the door leaf (10), wherein a first outer boundary surface (102) of the guide web (100) forms a surface for a first guide device (32) and the second outer boundary surface (104) of the guide web (100) forms a second guide surface (104) for a second guide device (34). Magnetic devices (1000, 1010, 1100) can be arranged on the door leaf and on the guide bar for guiding in a contactless manner.

Disclosed is a roller blind with a heat insulation function. The roller blind with a heat insulation function of the present disclosure includes a roller rotatably mounted in a frame, a heat insulation sheet configured to be wound and unwound on the roll, a plurality of tubular sheets attached to one surface of the heat insulation sheet and formed to have openings at both ends thereof, and a pair of rail members provided to extend in a direction in which the heat insulation sheet is unwound so as to block air from moving through the openings at both ends of the plurality of tubular sheets. According to the present disclosure, the roller blind with a heat insulation function is configured to effectively block heat in hot weather or cold in cold weather from being transferred to a room through a window.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly mounted in at least one of: the top portion and the bottom portion. The frame includes a top portion, a bottom portion, and two jambs forming first slots extending lengthwise along at least a portion of the jamb. The first slots each include a screen edge retention feature. The screen assembly includes a roller assembly substantially hidden from view, a screen material attached to the roller assembly, and a plurality of raised features. Edges of the screen material extend into the first slots. The raised features are attached to each of the edges of the screen material. The raised features are configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.
