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.

A door sill has a substrate having a recessed upward open channel formed therein, an extruded aluminum deck that at least partially receives the substrate, at least one threshold cap, an interior face cap that covers a portion of the substrate, and a lock key. A first portion of the threshold cap is coupled to the extruded aluminum deck. A second portion of the threshold cap is positioned in the recessed upward open channel adjacent a portion of the interior face cap. A portion of the lock key is press fitted intermediate the second portion of the threshold cap and the portion of the interior face cap. A seal is formed between the second portion of the threshold cap and the interior face cap. The seal is positioned proximate the inside wall of the upward open channel formed in the substrate above the bottom surface of the upward open channel.

A seal for an overhead door includes a first sidewall, and a second sidewall that extends from the first sidewall. The first and second sidewalls extend beyond a bottom corner of the overhead door to cover an opening formed by compression of an astragal attached to a bottom surface of the overhead door.

A replacement weather seal for use with a garage door having an existing two-part weather seal previously installed on the garage door. The existing weather seal has a rigid base fastened to a support frame surrounding the garage door, and a flexible combination cover and flap portion integral with the rigid base. The replacement weather seal replaces the flap portion of the existing seal but leaves the rigid base that is fastened to the support frame. The replacement weather seal comprises a main body which attaches to the rigid of the existing weather seal. Two sealing flaps are integrally molded to opposite edges of the main body, which flaps deflect and form a weather-tight seal with both the garage door and the existing rigid base. An L-shaped curb structure connects with the main body and positions the replacement weather seal on the existing weather seal rigid base.

Systems and methods for rectifying excessive bottom or head clearances of door assemblies are disclosed. An example system may comprise a door cap straight component installed on a first side of a fire door; a door cap L-shaped component installed on a second opposite side of the fire door; at least one intumescent strip seal fitted with the door cap L-shaped component; and end caps installed on two narrow ends of the fire door.

An automatic door seal is provided for sealing the gap between the lower edge of a door and a threshold. The seal is magnetically actuated so as to move downward into sealing engagement with the threshold when the door is closed and raises out of engagement when the door is opened. A transmission assembly converts horizontal movement from the magnetic force into vertical movement for the seal. Springs provide a reset force when the magnetic force is eliminated so as to retract the seal strip whenever the door is moved from the closed position.

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.

A draft protector for a double door system has a longitudinally extending body having a first portion, a second portion, and a foldable central connecting portion disposed between the first and second portion. The first portion is positioned adjacent a first door and the second portion is positioned adjacent a second door, and either the first or second portion is folded over and in parallel alignment with the first or second portion when the first or second door is in an open position.

Door systems and door hardware components are described herein, along with methods of installing the door systems and components.

A thermally-broken ornamental door includes a thermally-broken door and a thermally-broken jamb through which thermal transfer is greatly minimized. The thermally-broken door includes an outer panel and an inner panel that are minimally connected through a plurality of door bridging strips. The thermally-broken jamb includes an outer jamb frame and an inner jamb frame that are minimally connected through a plurality of jamb bridging strips. An insulating foam panel is present between the outer panel and the inner panel while an insulating foam core is present between the outer jamb frame and the inner jamb frame. A window assembly is hingedly mounted into the thermally-broken door and includes a retaining spacer frame that minimizes thermal transfer from an exterior environment to an inner window frame through a glass panel of the window assembly. The retaining spacer frame additionally provides structural support to the glass panel.
