A method of forming a thermally enhanced extrudate for a door or window includes providing an extrudate including a channel shaped to receive glass or a frame and having a completely enclosed cavity. The method further includes forming openings in a first flange of the extrudate. The remaining portion of the first flange form bridges that extend between a first wall and a second wall. The method further includes position a flowable material into the cavity through the openings. The flowable material cures to create a solid insulation material in the cavity and the bridges resist warping of the extrudate as the flowable material cures.

The invention is a photovoltaic system mounted with brackets to the inside surface of a window. The brackets are adhesively attached to the window. The system comprises photovoltaic modules on a substrate along with a sheet of material which is visually similar to the substrate which are both attached by the brackets to the interior surface of a window, facing towards the outside of the building. The light incident side of the substrate with photovoltaic cells faces the exterior of the building facing the sun. Electrical connectors are integrated into the substrate and connected to solar cells within the photovoltaic modules, thus providing electrical connection of the system to external electrical devices or electrical systems near the window that require power.

A frame structure, a method for manufacturing the same and a device is provided. The frame structure includes at least one frame bar, an injection cavity and a plastic material; the injection cavity is located in an interior of the frame bar and extends in a length direction of the frame bar, and the plastic material is filled in the injection cavity, wherein an expansion coefficient of the plastic material is lower than an expansion coefficient of the material from which the frame bar is made.

A panel fastening device that is configured to move together a first frame of a first panel unit having a first glass panel mounted within the first frame and a second frame of a second panel unit having a second glass panel mounted within the second frame. The device includes a suction cup is configured to be coupled to and released from the first glass panel of the first panel unit, and a structure is configured to be pressed against and released from the second frame of the second panel unit.

The invention relates to a vertical sliding element including an element frame and a sash which can be moved in the vertical direction relative to the element frame. In the closed position of the sash, one fitting chamber each is formed in the intermediate spaces which are laterally limited by mutually facing side faces of the sash and the element frame. Each fitting chamber is provided with a guide rail and guide elements guided in the guide rail. The sash is connected to the guide elements via a scissors' arrangement having a plurality of parking scissors. The scissors arrangement is designed for parallel parking of the sash in a partially open position, in which the sash is positioned in front of an opening in the element frame, seen in the horizontal direction, and wherein the guide elements are designed to move the sash parked in parallel in the vertical direction by moving the guide elements in the guide rails.

The present invention relates to an installation structure of a glass fixing gasket and a window glass panel fixing bracket, which fixes a window glass panel of a fixed window included in a sliding window system which comprises a segmented window frame and, more specifically, to an installation structure of a glass fixing gasket and a window glass panel fixing bracket, wherein the glass fixing gasket and the window glass panel fixing bracket are installed between a window frame portion which supports three sides (an upper surface, a lower surface, and one external side surface that is not a middle bar side surface) of a fixed window included in a sliding window and a window glass panel provided as a double-pane, in order to provide a sealing function for preventing ventilation and a function of stably fixing the window glass panel against high wind pressure (wind pressure resistance), and moreover, to ensure maximum heat insulation performance.

Exemplary implementations of a thermally-efficient slidable fenestration assembly are glass window systems or glass door systems having one or more sliding glass panels. The fenestration assemblies are adapted to be mounted in an architectural structure such as a building or house. Accessory channels in the fenestration framework may be provided to facilitate nail-fin, retro-fit or screen adaptors as means to attach the assembly to the surrounding architecture. Stiles, tracks and rails of the assembly are specifically configured to reduce heat transfer across the fenestration assembly, while simultaneously maintaining the structural integrity and durability of the overall assembly. Certain stile, track and rail components may comprise materials of relatively low conductivities. Preferred stile configurations include interlock elements arranged to reduce the assembly's vulnerability to tampering from a position outside of the fenestration.

The present application relates to an arrangement for reducing thermal energy loss through a sill assembly of the type used with a door or window. The sill assembly includes at least one sill member. The at least one sill member has a hollow region therein. The sill assembly further includes a baffle disposed within the at least one sill member. The baffle spans a length of the at least one sill member and divides the at least one sill member into a plurality of chambers thereby limiting interaction of warmer air and cooler air within the at least one sill member. The baffle reduces heat transfer through the hollow region via convection.
