The insulation system includes opening wall, substrate wall, thermal closure, insulation and exterior trim. A window structure can be coupled to cover opening, while other structures are contemplated. Depending on the configuration, tape strips and/or seals such as caulk seals may be employed as needed to seal the structure.

A fenestration assembly includes a glazing unit includes a pane spacer between exterior and interior panes proximate glazing unit edges. A fenestration frame is coupled around the glazing unit and includes a frame core extending around the glazing unit. The frame core includes a unitary core wall including a composite material that is hollow and extends continuously from a core interior face to a core exterior face. A metal glazing cap is coupled with the frame core. The metal glazing cap having a cap end indirectly engaged with the glazing unit along the interior pane, and the cap end is remote from the pane spacer. Each of the core exterior face, the pane spacer and the metal glazing cap are thermally isolated from each other with the frame core including the unitary core wall.

A window sill pan for directing moisture toward an exterior side of a window frame may have a base member mounted along a window frame sill and sloped to drain liquid toward the exterior side of the window frame, corner members adjacent left and right ends, respectively, of the base member, with each corner member having a stud part, which extends up at least a lower part of a respective stud of the window frame, and a sill part mounted along the window frame sill toward the base member, and a membrane adhered to, and forming a water impermeable envelope that covers, external surfaces of the base member, the corner members, the window frame sill and the lower parts of the studs.

Multi-piece, flexible, sill pan assemblies and methods of installation are disclosed. Method of installation of a sill pan assembly for pocket door systems such as single- and double-door versions as well as multi-panel pocket doors. The sill pan assembly has a first flexible end dam member, a second flexible end dam member, a flexible outside corner member, and a flexible insert. Methods of installation of a sill pan assembly for a double-pocket door. The sill pan assembly having a first flexible end dam member, a second flexible end dam member, a first flexible outside corner member, a second flexible outside corner member, and a flexible insert.

An expandable flashing device comprises first and second pieces of flashing material that overlap one another with hems or folded edges located on opposite lateral sides of the pieces that hold the pieces together, yet allow the pieces to slide or shift with respect to one another to selectively change the length of the device. In a first stowed position, the pieces overlap one another and in an expanded second position, the pieces may be pulled apart to increase an overall length of the pieces. The maximum length of material that overlaps between the pieces is defined as the overlap range. The overlap range defines the range to which the device can be shortened or lengthened to fit a particular installation. A flashing system and a method of installing flashing are also disclosed.

A flashing includes a first edge, a second edge opposite from the first edge, a first surface, and a second surface on an opposite side of the flashing from the first surface. The first surface and the second surface extend between the first edge and the second edge. The first surface includes a hydrophobic region and a hydrophilic region.

A method for the production of a sealing tape roll of flexible, compressible foam with at least one barrier layer extending in the radial direction, which is arranged axially between two layers of foam. The method includes providing a foam web of a flexible foam; applying a first barrier layer to a first surface of the foam web; and introducing at least one first cut into the first surface of the foam web and introducing at least one second cut into a second surface of the foam web opposite the first surface to form parallel sealing tape strips. A connecting section remains between two adjacent sealing tape strips. The sealing tape strips are then folded over in the area of the connecting sections to produce a foam-barrier layer web, and the foam-barrier layer web is wound up into a sealing tape roll.

A water trough window seal trim assembly for preventing water leakage includes a plurality of trim sections comprising a top trim section, a left trim section, and a right trim section. Each of the plurality of trim sections comprises a bottom piece, an exterior perpendicular piece, an interior perpendicular piece, and a parallel piece. The bottom piece has an exterior end, an interior end, a top face, and a bottom face. The exterior perpendicular piece is perpendicularly coupled to the top face at the exterior end. The interior perpendicular piece is perpendicularly coupled to the top face proximal the interior end. The parallel piece is perpendicularly coupled to each of the exterior perpendicular piece and the interior perpendicular piece to form a water trough. A pair of corner connectors perpendicularly couples each of the left trim section and the right trim section to the top trim section.

A corner flashing system is provided for sealing the corners of recessed window frames against moisture penetration. In a preferred embodiment, the system comprises first and second double-flap members, a half-cube member, and caulking. The first and second double-flap members, and the half-cube member are preferably made of asphalt or petroleum based material. In another preferred embodiment, the system comprises one double-flap member, a modified half-cube member, and caulking. In another preferred embodiment, the system comprises a single member that combines a double-flap member and a half-cube member, and caulking. In another preferred embodiment, the system comprises a combination member, a double-flap member, and caulking.

A clip fastening system for securing a window in a window opening without the use of penetrating fasteners is disclosed. The clip fastening system includes a flange that extends in an inward direction from and around the window opening, a groove that is formed through a facing of a window frame of the window and that extends around the perimeter of the window frame, and a clip mutually engaged with the flange and the groove, thereby securing the window frame within the window opening.
