Abstract
A moisture resistant film is for covering an architectural structure. The film includes a flexible membrane defining a plane and a first plurality of spaced apart, discrete embossings formed in the membrane extending outwardly of the plane. The embossings are formed in rows in an x-direction and in columns in a y-direction. The rows are parallel to and spaced from one another and the columns are parallel to and spaced from one another. A method and tool for making the film are also disclosed.

A method of forming a moisture resistant flexible film comprising the steps of:
- laminating a first oriented plastic layer and a second oriented plastic layer to one another where the orientations of the first and second layers cross at an angle between but not equal to zero degrees and 180 degrees relative to one another to form a flexible membrane defining a plane;
- and
- forming in the flexible membrane a first plurality of spaced apart, discrete embossings extending outwardly of the plane, the embossings formed in rows in an x-direction and in columns in a y-direction, the rows being spaced from one another and the columns being spaced from one another.
