An insulating body for multi-shell construction elements for spacing apart and thermally separating at least two profiled section elements relative to each other has a base member with a first side and a second side opposite the first side. Fastening projections are arranged on the first and second sides of the base member and secure the insulating body in receptacles of the profiled section elements. At least the first side has two of the fastening projections. The base member has a hollow chamber with an inner guiding contour for receiving and guiding fitting parts. A multi-shell construction element with at least two profiled section elements is provided with at least one such insulating body.

Embodiments described herein may be directed towards a male and female gasket coupling for securing adjacent window frames. In accordance with the present disclosure, the male gasket may comprise a head portion that creates a seal inside a cavity of the female gasket. The female gasket may further be enabled to collapse on itself as it engages a surface of the male gasket. The seal may be maintained when the male and female gaskets move toward each other or when the male and female gaskets move away from each other due to fluctuations in temperature.

Provided herein are thermal break structural members for use in fenestration assembly products. In some embodiments, the thermal break structural member is monolithic with an infill retainer, being designed to bear a structural load while maintaining the overall integrity and thermal performance of the conjoint fenestration unit.

A window system includes a frame, a glazing assembly held within the frame and including a glass stop attachable to the frame, wherein attaching the glass stop to the frame defines an air pocket between the glass stop and the frame, and a thermal dampening device positioned within the air pocket and defining one or more discrete cavities.

A composite structure has a pair of parallel aluminum extrusions bridged by a polymer cap and defining a U-shape hollow. The hollow is filled with an expandable foam that adheres to and mechanically interdigitates with the extrusions, which have channels for receiving insertion legs of the extrusions and have extensions, which the foam encapsulates. End caps may be used to further delimit the hollow. The caps and the foam have a thermal conductivity less than that of the extrusions, providing a thermal break. An upper cap may be used and may incorporate features to compensate for the foam expansion. Excess foam may be trimmed. A forked tool may be used to hold the extrusions during joining.

A high-performance fenestration system that includes a pressure chamber formed between longitudinally adjacent fenestration members. The pressure chamber is positioned on one side of the thermal break. The fenestration system can be configured so to create a continuous pressure chamber around the closed perimeter of the fenestration between the frame and sash. The resulting fenestration system enjoys significantly better water penetration resistance as compared with conventional high-performance doors and windows. Because of the positioning and structural configuration of the pressure chamber, the fenestration system can be configured to accept different hinge styles including Euro-style and American-style hinges without significant loss of performance. In addition, the system can accept American-style door hardware or Euro-style door hardware.

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 plastic thermal barrier connects an inner shell and an outer shell of a window frame or a door frame. The thermal barrier includes a first part that is provided with a component for connecting it to an inner shell and an outer shell. The thermal barrier further includes a second part, whereby these parts are connected to one another in a hinged way by means of a film hinge and are provided with mutually complementary elements of a snap connector configured to fasten the two parts together.

A pre-formed insert with stable dimensions for mechanical insertion into a hollow member and that reduces the Nusselt number and convection across the hollow member. The insert may be formed of a low heat conducting material like PVC and have extensions and internal voids that impede convection in the hollow and conduction through the insert. The inserts may be used in heads and sills of aluminum windows, doors and frames. In one embodiment, an insert is received in an open hollow and may cooperate with an insert in a frame hollow to decrease convection at the head end of a sliding window or door. An insert may be placed within the hollow of a window or door beside a roller assembly.
