ABSTRACT:
The present invention provides an improved method for making a solar control sheet having one or more metal layers. In the prior art solar control sheets, each metal layer would normally be non-porous so that water vapor would not be readily transmitted therethrough. However, in this invention the metal layer is rendered porous because it is deposited on a porosity inducing surface. The porosity inducing surface may be the surface of a porous primer layer or a surface which has been roughened. Consequently when the solar control film of this invention is mounted on a window with a water based mounting media, the water can quickly evaporate through the film without causing undesirable cloudiness which is normally associated with water which becomes trapped between the film and the window.
