A specification for replacing single pane aluminum windows should distinguish general technical principles from product-specific claims. The following sources provide the first; final dimensions, ratings and options must still come from the selected DAW system and project documents.
Department of Energy — Fenestration Air Leakage Context
Source summary: DOE highlights air leakage as part of window and door energy performance. The installed assembly—not glass alone—determines how effectively the opening limits uncontrolled air movement. In relation to replacing single pane aluminum windows, the source helps separate a general design principle from the product-specific information that still requires confirmation.
Connection to Replacing Single Pane Aluminum Windows: The project link is installation quality: existing-opening assessment can affect uncontrolled air movement even when the glass package itself is well selected.

Department of Energy — Moving vs. Stationary Air Seals
Source summary: Energy guidance treats fixed perimeter cracks differently from joints that repeatedly move. A durable opening therefore needs both a sound stationary perimeter seal and serviceable weatherstripping where panels or sashes operate. For replacing single pane aluminum windows, this summary is used as an external check on the project decision, not as a substitute specification.
Connection to Replacing Single Pane Aluminum Windows: Applied to replacing single pane aluminum windows, the DOE distinction helps assign different details to stationary perimeter sealant and moving weatherstrips; both affect long-term serviceability.

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 replacing single pane aluminum windows, the source helps separate a general design principle from the product-specific information that still requires confirmation.
Connection to Replacing Single Pane Aluminum Windows: The relevance to replacing single pane aluminum windows is direct whenever glass is within the door or adjacent hazardous location: the project team should confirm the required safety glazing for that specific opening.

Use of sources: The points above are design checks, not substituted DAW specifications. The selected replacing single pane aluminum windows configuration should be verified against current product information, approved drawings and the project jurisdiction.
