Three independent technical lenses are relevant to aluminum windows company: 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. Department of Energy — Efficient Windows, Doors and Skylights
Source summary: DOE notes that air leakage through fenestration can be a meaningful source of heat gain or loss. This puts installation, frame joints and operable seals alongside glass performance in the overall energy discussion. In relation to aluminum windows company, the source helps separate a general design principle from the product-specific information that still requires confirmation.
Connection to Aluminum Windows Company: Applied to aluminum windows company, the source supports checking frame/perimeter leakage paths and operable seals rather than assuming a glass value describes the whole opening.

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. The relevance to aluminum windows company is therefore procedural: use the principle to verify the opening, then confirm the selected DAW configuration separately.
Connection to Aluminum Windows Company: For aluminum windows company, separate the fixed frame-to-wall joint from moving seals. Frame sightline should be detailed so cleaning and replacement do not compromise the perimeter air/water line.

U.S. Consumer Product Safety Commission — Safety Glazing
Source summary: The federal architectural-glazing rule covers glazing used in doors and sliding patio doors. Its purpose is injury reduction, which is why glass type and hazardous location must be part of the door specification. For the aluminum windows company review, this source is being used to frame the opening-specific check rather than to supply a DAW product value.
Connection to Aluminum Windows Company: The relevance to aluminum windows company 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.

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.
