Abstract:
A multilayer laminate and, more particularly a variable transmission window, which comprises: a) a thermochromic layer b) a photochromic layer wherein the thermochromic layer exhibits a net increase in its ability to absorb UV, visible, and/or near infrared light energy as the temperature of the system increases and a net decrease in its ability to absorb UV, visible and/or near infrared light energy as the temperature of the system decreases within the active range of the thermochromic layer.
Abstract:
An environmentally durable window glass unit is provided with improved edge sealing to protect the interlayer of one or more laminates that make up the unit. The insulated glass unit includes a first pane comprising an outboard glass sheet, an inboard sheet and an interlayer therebetween. The inboard sheet is smaller in length and/or width than the outboard sheet. The glass unit also includes a second pane spaced away from and sealed to the first pane. A gas space is located between the inboard sheet of the first pane and the second pane. A spacer is positioned between the first pane and the second pane. The spacer is adhered to the inboard sheet of the first pane and to the second pane with a primary seal. A second seal adheres the outboard sheet of the first pane to the second pane.
Abstract:
A directly-coated PVB film or sheet. The film or sheet includes a PVB layer that includes no plasticizer or less than about 5 weight percent plasticizer and a conductive or reflective coating. The conductive or reflective coating directly coats the PVB layer. The PVB film or sheet is includable in a laminate.
Abstract:
Alternating layers of a first moisture sensitive layer are formed with a second desiccant containing layer. The desiccant containing layer removes moisture from the first moisture sensitive layer and maintains the first layer in a relatively dry condition.
Abstract:
An energy efficient, thermochromic device that may be used to allow sunlight or solar radiation into a building or structure when sunlight is absent or at high sun angles and substantially blocks solar radiation when sunlight is directly on the window.
Abstract:
Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes.
Abstract:
A combination of layers comprised of: 1) a first LETC layer; 2) a second LETC layer and 3) a separator layer between the two LETC layers 4) an additive within at least one of the LETC layers and the separator layer wherein when the layers are laminated between two sheets of clear glass the color coordinate values of the laminate are about −8.5≦a*≦about 8.5 and about −8.5≦b*≦about 8.5 throughout the temperature range of about 0° C. to about 85° C.
