There is a frame insulator that covers a window or door frame. A door or window has one or more panels that are supported by frame members. The frame members have interior surfaces and exterior surfaces. The one or more panels are mounted on the frame members. The interior surfaces or the exterior surfaces or both are enclosed by sheets of cross-linked polyethylene foam extending adjacent to the one or more panels and forming frame insulators.

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.

An optically clear, siliconized plastic film(1) adhesively mounted on an architectural glass substrate(7) creates a highly efficient seat for adhere able plastic foam laminates. This will allow the plastic foam laminates to be seated on the siliconized plastic film creating complete removability and reusability. Additionally, numerous adhesives can be specified for the plastic foam laminates wherein adhesive residue left on the glass will not be a design factor. In one embodiment the siliconized plastic film allows double sided tape(2) to be placed on the periphery of the laminate to achieve an excellent, glass removable bond for seating the film on a glass substrate. This makes an excellent, impervious seal. Also, heat transfer reductions range from approximately 89-98% depending upon the temperature extremes in Winter and Summer. Further, this invention provides good light transmission, improves privacy for bedroom glass, creates a display for brilliant artwork, reduces dust accumulations and creates instant removability. The material cuts as easy as paper and will be very simple to fabricate; therefore, this invention can be constructed with simple kits and installed by unskilled, do-it-yourself users.

A building aperture cover frame, such as a window frame, having at least one frame profile for framing an insulated glass unit, where the frame profile includes an insulating core of insulating polyurethane foam core material enclosed by a core surface of the insulating core, where the insulating polyurethane foam core material having at least 85% by weight polyurethane, and where the insulating polyurethane foam core material is of a material density of less than 60 kg/m.sup.3, such as less than 50 kg/m.sup.3, preferably less than 40 kg/m.sup.3, a profile shell encapsulating the insulating core and having an inner shell surface facing the core surface, where the profile shell is made of at least 90% by weight polyurethane, and where the profile shell is of a material density of at least 600 kg/m.sup.3, such as at least 750 kg/m.sup.3, preferably at least 850 kg/m.sup.3, and one or more metal reinforcement element(s) located between opposing parts of the inner shell surface and the core surface.

The present invention relates to a thermal insulation structure of a door frame in which a moving window (sliding window) constituting a sliding window system is installed, and more particularly, a two-side supporting frame window supporting both sides of a glass window constituting a sliding window system, more particularly, relates to an insulating structure in a side section of a door frame into which the side portion of the sliding window that is moved when closing the sliding window of the supporting frame window type is pocketed, that is, the insulating structure of the side section of the door frame.

A frame assembly for a door or a window includes an inner frame portion, an outer frame portion spaced from the inner frame portion by one or more thermal breaks, and a first insulating and structural assembly positioned between the inner frame portion and the outer frame portion. The insulating and structural assembly includes heat-insulating portions for inhibiting the transfer of heat between the inner frame portion and the outer frame portion, and structural portions for retaining the inner frame portion in position relative to the outer frame portion. The inner frame portion and the outer frame portion define a longitudinal direction extending peripherally around the door or window. The heat-insulating portions alternate in the longitudinal direction with the structural portions.

A fenestration assembly includes a fenestration frame includes one or more frame members. The fenestration frame is coupled with one or more panels. Each frame member includes a coextruded foam polymer frame member. The coextruded foam polymer frame member includes a foam polymer core and a polymer shell jacketing the foam polymer core. The polymer shell is coextruded with the foam polymer core. The polymer shell braces the foam polymer core against deformation.
