A wall panel system may include a bottom drop seal assembly that maintains a constant force relative to a floor portion of an environment through a damper. The wall panel system may include an automatic top seal assembly that seals a gap between the movable wall panel system and a ceiling of the environment. The moveable wall panel system may include multiple panels and a plurality of seals positioned between adjacent panels to seal a gap between the adjacent panels.

A fenestration system may comprise a closure element, such as a door or window. The closure element is movable relative to a frame between open and closed positions. The frame surrounds a fenestration opening, such as a doorway. The fenestration system may also comprise a carrier mounted to the closure element and movable relative to the closure element between extended and retracted positions. A weather strip is attached to the carrier and arranged to contact the frame in the extended position of the carrier. One or more retraction magnets may be arranged to exert a first magnetic force on the carrier to move the carrier into the retracted position in the open position of the closure element. One or more extension magnets may be arranged to exert a second magnetic force on the carrier to move the carrier into the extended position in the closed position of the closure element.

Disclosed herein is a sealing assembly for moving a slidable panel for engagement with and disengagement from sealing means, the sealing assembly comprising a linkage assembly which connects a handle and at least one roller assembly having roller wheels, the sealing assembly being configured to be adjustable, by manipulation of the handle, such that the at least one roller assembly and the slidable panel supported thereby are movable between a first position where the slidable panel is in contact with sealing means thereby providing weatherproofing and a second position where the slidable panel is free of the sealing means and the panel is able to move freely relative to an outer frame, and wherein the linkage assembly is configured to as to provide a variable force through the handle when the at least one roller assembly and supported panel is moved between the first and second positions.

A window or door includes a fixed frame with a first sash arranged displaceable thereon. A seal is arranged on the fixed frame, the sealing lip of which can be moved or pivoted and pressed onto the front or rear of the first sash. The moving process can be carried out by at least one first trigger element or by a plurality of trigger elements. The first trigger element or the trigger elements can be actuated by a first projection or a plurality of projections. A first wedge seal can be provided between the first sash and the fixed frame, which is preferably wedge-shaped both in the main plane of the frame and perpendicular to the main plane of the frame. Between two sashes, in the region of the central break, L-shaped seals can be provided which engage one behind the other in the closed state of the two sashes.

Systems and methods for providing a drop seal assembly which is concealed within an opening in the bottom of a sliding door panel of a top-hanging sliding door. The drop seal assembly may include bottom guide which defines a downward facing elongated slot or track which receives a sill guide therein. The drop seal assembly also includes a drop down acoustic seal which automatically drops down to contact the floor surface below the door panel when the door panel is moved from an open position into a closed position. The distance that the seal drops down upon closing of the door panel may be selectively adjustable to accommodate variances in the air gap between the door bottom and the floor surface due to particular installation conditions. A concealed magnetic bottom seal activator may be used to provide self-adjusting activation of the door bottom seal assembly using two opposing magnets.
