Three independent technical lenses are relevant to aluminum windows california: how the opening is used, how glass is treated at door/window locations, and how stationary versus moving joints are sealed. Each source below is summarized for that purpose.
U.S. DOE — Fenestration Energy Purchasing Guidance
Source summary: DOE purchasing guidance calls attention to fenestration air leakage as an energy pathway. A high-performing glass package can therefore be undermined if the frame perimeter or operable joints are poorly controlled. For aluminum windows california, this summary is used as an external check on the project decision, not as a substitute specification.
Connection to Aluminum Windows California: The project link is installation quality: location-specific code/climate verification can affect uncontrolled air movement even when the glass package itself is well selected.

U.S. Department of Energy — Air-Sealing Guidance
Source summary: DOE separates stationary joints from moving joints: caulk is generally used at fixed cracks around frames, while weatherstripping is used where doors and operable windows move. The two joint types need different detailing and maintenance. For the aluminum windows california review, this source is being used to frame the opening-specific check rather than to supply a DAW product value.
Connection to Aluminum Windows California: The connection to aluminum windows california is the joint map: identify which gaps never move and which cycle with the opening, then detail and maintain them accordingly.

U.S. CPSC — Architectural Glazing Safety Standard
Source summary: CPSC identifies exterior/interior doors and patio-type sliding glass doors among the architectural products covered by the federal safety-glazing standard. The location of glass within a door assembly therefore carries safety implications beyond appearance. In relation to aluminum windows california, the source helps separate a general design principle from the product-specific information that still requires confirmation.
Connection to Aluminum Windows California: For aluminum windows california, this connects glass selection to where people can contact the glazing. Treat safety-glass confirmation as part of the opening review, not a late finish decision.

Specification note: Keep these external principles in the technical review, but use the confirmed DAW product and project documents as the controlling source for final values and compliance.
