Infill electrochromic windows
First Claim
1. A method of installing a new window registered with a pre-existing window in a building, the method comprising:
- providing a spacer having an adhesive applied to surfaces facing the pre-existing window and the new window, the spacer positioned between the pre-existing window and the new window, the spacer being provided proximate a peripheral region of the pre-existing window and the new window, wherein a pocket is formed between the pre-existing window and the new window and is defined at its edges by the spacer;
piercing the spacer with a tube; and
applying vacuum to the pocket to adhere the spacer to the pre-existing window and the new window, via a vacuum pump in fluidic communication with the tube, wherein gas leaving the pocket passes through a check valve after passing through the tube, and wherein vacuum is applied until a pressure within the pocket is reduced to about a target pressure or until a deflection of a lite of the pre-existing window or the new window is at about a maximum deflection and wherein the target pressure is determined at least in part based on characteristics of the pre-existing window including at least one of an area of the pre-existing window, a thickness of the pre-existing window, and/or a material of the pre-existing window.

Abstract
Various embodiments herein relate to methods, structures, tools, installation systems, etc. for retrofitting a new electrochromic window in a pre-existing window recess. In many cases, the new electrochromic window is installed parallel to a lite of a pre-existing window, with the resulting structure including the new electrochromic window, the pre-existing window, and a pocket that forms between them. Installation of a new electrochromic window in tandem with a pre-existing window results in many benefits including improved insulation (e.g., due to the presence of the additional air pocket(s) and lite(s)), improved climate control (e.g., due to the ability to control the amount of sunlight entering the building via the electrochromic window), and enhanced aesthetics.
