A specification for replacing glass in old 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 glass in old aluminum windows, the source helps separate a general design principle from the product-specific information that still requires confirmation.
Connection to Replacing Glass in Old Aluminum Windows: For replacing glass in old aluminum windows, this means existing-opening assessment and installed joint quality belong in the energy discussion alongside glazing. A specification should not reduce performance to glass alone.

U.S. DOE — Caulking and Weatherstripping
Source summary: DOE describes caulking as a treatment for stationary gaps and weatherstripping as a seal for moving components. For fenestration, that distinction helps separate the frame-to-wall perimeter from operable panel or sash contacts. In relation to replacing glass in old aluminum windows, the source helps separate a general design principle from the product-specific information that still requires confirmation.
Connection to Replacing Glass in Old Aluminum Windows: For replacing glass in old aluminum windows, separate the fixed frame-to-wall joint from moving seals. Replacement tolerance should be detailed so cleaning and replacement do not compromise the perimeter air/water line.

CPSC — Glazing in Doors and Sliding Glass Doors
Source summary: CPSC’s scope expressly includes glazing in doors and patio-type sliding glass doors. For project teams, that means large glass areas at human contact locations require a safety-focused specification, not just a visual glass choice. In relation to replacing glass in old aluminum windows, the source helps separate a general design principle from the product-specific information that still requires confirmation.
Connection to Replacing Glass in Old Aluminum Windows: With replacing glass in old aluminum windows, large or highly visible glass areas still need location-appropriate safety review; appearance and safety should be specified together.

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