Abstract
Abstract Heat transmission through a solid window is reduced by: A. providing a light transparent plastic sheet having a transparent metal layer on one surface of the sheet, the layer characterized as reflective to incident heat radiation, and applying the sheet to the window, and B. providing an oil film at the interface between the sheet and window to retain the sheet to the window, and C. smoothing the sheet to eliminate any bubbles that form at the interface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
84 words
The method of reducing heat transmission through a solid window, that includes, a. providing a light transparent plastic sheet having a transparent metal layer on one surface of the sheet, the layer characterized as reflective to incident heat radiation, and applying the sheet to the window, and b. providing a mineral oil film at the interface between the sheet metal layer and window to retain the sheet to the window, and c. smoothing the sheet to eliminate any bubbles that form at the interface.
Claim 2
Independent Claim
84 words
The method of reducing heat transmission through a solid window, that includes, a. providing a light transparent plastic sheet having a transparent metal layer on one surface of the sheet, the layer characterized as reflective to incident heat radiation, and applying the sheet to the window, and b. providing a mineral oil film at the interface between the sheet metal layer and window to retain the sheet to the window, and c. smoothing the sheet to eliminate any bubbles that form at the interface.
Claim 3
Dependent Claim
12 words
