    Abstract: A spacer profile for a spacer frame of an insulating pane unit includes a hollow profile body made of plastic with a chamber defined therein. The hollow profile body extends in a longitudinal direction and includes an inner wall, an outer wall, a first side wall and a second side wall, which are connected to the inner and outer walls to form the chamber. First and second reinforcing layers made of a metallic material respectively extend on the first and second side walls and partially on the outer wall so as to be spaced apart by a first distance. A diffusion barrier layer is formed directly on the outer wall between the first and second reinforcing layers and is connected thereto in a diffusion-proof manner in order to form a heat-insulating diffusion barrier. An insulating pane unit includes at least two panes with such a spacer frame disposed therebetween.

The panels are made of spaced and parallel double or multiple layers of transparent plastic sheets, air-tightly mounted on to a frame of plastic, wood, aluminum or other materials. The frame of the panels has seals on the sides for air-tight fitting into the interior structure of the windows, and has different shapes, colors and styles, if necessary, to match the design of the windows. The panels can also be designed to fit into the interior structure of glass doors to provide supplementary insulations. The panels can increase the R-value of double pane windows or glass doors from current about 3 to up to 8 or more, dramatically reducing energy losses.

    Abstract: A multi-sheet glazing unit includes a closed spacer frame, the spacer frame has one side having a pair of legs joined to a base to provide the spacer frame with a U-shaped cross-section. An inner sheet has an edge mounted in an edge receiving member mounted between the legs of the U-shaped side of the spacer frame. The remaining edges of the inner sheet are within the interior of the closed spacer frame and spaced from the spacer frame. The inner sheet is held within the spacer frame by sheet retaining members mounted to the spacer frame. A sheet e.g. glass sheet is secured by a moisture-impervious adhesive to outer surface of each of the legs of the spacer frame. One type of sheet retaining members has a horizontal member and a vertical member, and a locking member. The locking member is mounted on the horizontal member spaced from the vertical member to form a groove to hold the inner sheet within the closed interior of the spacer frame.

  • Patent number: 6457294
    Abstract: An insulating glass unit including a first pane of glass, a second pane of glass, and a spacer system. The spacer system includes (i) a spacer positioned between an inner surface of the first pane of glass and an inner surface of the second pane of glass and (ii) a sealant system for adhering the inner surfaces of the glass panes to the spacer. The sealant system includes at least one sealant having (a) at least one thermoplastic hot-melt material having a melt temperature ranging from about 125° F. (51° C.) to about 250° F. (121° C.), and (b) at least one curable material. The sealant, when cured, forms a covalent bond between the spacer and the panes. The sealant has an initial hardness ranging from about 25 Shore A to about 450 Shore A and a post-cure hardness measured about 48 hours thereafter ranging from about 30 Shore A to about 50 Shore A.

  • Patent number: 6415561
    Abstract: A multi-sheet glazing unit includes a spacer frame having a pair of legs joined to a base to provide a U-shaped cross-section. A sheet e.g. glass sheet is secured by a moisture-impervious adhesive to outer surface of each of the legs of the spacer frame. A plurality of sheet retaining members in a spaced relationship to one another are maintained on the legs of the spacer frame between the glass sheets and spaced from the base. The sheet retaining members each have a groove for receiving edge of a sheet e.g. glass sheet to secure the sheet between the outer sheets. The sheet retaining member includes a first part having a vertical stop and a non-vertical platform e.g. horizontal platform and an elongated securing member detachably secured on the horizontal platform spaced from the vertical stop to form the groove. A method for making the unit is also disclosed.

  • Patent number: 6389779
    Abstract: The invention relates to a spacer profile of an elastically-plastically deformable material with low heat conductivity for a spacer frame to be mounted in the marginal area of at least two spaced-apart panes by forming an intermediate pane space, whereby the spacer profile comprises a chamber which has in one of its walls at least one elastically-plastically deformable reinforcement element extending along the chamber, and whereby the spacer profile has a diffusion-proof layer extending substantially over its entire width and length. In order to produce the profile through cold flexion, the lateral walls of the chamber are each provided with at least one reinforcement element.

  • Patent number: 6355328
    Abstract: A composite structure comprising a preformed flexible laminate in adhering contact with at least a first and second transparent or translucent panel members such as would be useful as an insulated glass unit. The flexible laminate contains an undulating spacer element either partially or totally embedded within a core material and has a polymeric coating on at least one surface thereof. The flexible laminate effectively seals the interior of the panel structure from air and/or moisture and maintains a desired distance between the panels. A multi-cavity extrusion die for forming the preformed flexible laminate has a core cavity for receiving the core material as well as the undulating continuous spacer element. Converging walls within the core cavity serve to embed at least one side of the spacer element in the core material and a land area forms a desired shape or configuration wherein the spacer element undulation is maintained.

  • Patent number: 6354052
    Abstract: A method of forming a composite profile including a hollow body with approximately parallel opposite walls and a covering sheet fixed against a first one of the walls includes heating a portion of the composite profile to form a temperature gradient. A hot forming projection is then pressed against a second one of the walls so as to bring the first wall into contact with the second wall at a formed region. At least one section of the profile is then pivoted about the formed region so as to produce a folding line.

  • Publication number: 20010047592
    Abstract: An integral metal spacer for insulated glass units and method of fabricating the spacer. The spacer defines a substantially closed cross-section contour having a bottom surface, a pair of sidewalls, and a pair of generally abutting inner surfaces. A gap may be defined between the adjacent inner surfaces. The three interior corners are defined by fully mitered sidewalls. A pair of bridges are provided to integrally interconnect the inner surfaces of adjacent spacer segments. The method of fabricating includes taking a roll of flat metal stock and completely punching all corner and other structures therein while the stock is planar; severing the punched stock into individual spacer members; roll-forming the individual members into a finished linear spacer piece; applying desiccant during roll-forming; applying sealant; thereafter folding the elongate member into a square spacer thereby locking the desiccant therein.
