A specification for manufacturer of aluminum windows and doors 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.
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 manufacturer of aluminum windows and doors, the source helps separate a general design principle from the product-specific information that still requires confirmation.
Connection to Manufacturer of Aluminum Windows and Doors: Applied to manufacturer of aluminum windows and doors, the source supports checking frame/perimeter leakage paths and operable seals rather than assuming a glass value describes the whole opening.

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. For the manufacturer of aluminum windows and doors review, this source is being used to frame the opening-specific check rather than to supply a DAW product value.
Connection to Manufacturer of Aluminum Windows and Doors: The connection to manufacturer of aluminum windows and doors is the joint map: identify which gaps never move and which cycle with the opening, then detail and maintain them accordingly.

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. The relevance to manufacturer of aluminum windows and doors is therefore procedural: use the principle to verify the opening, then confirm the selected DAW configuration separately.
Connection to Manufacturer of Aluminum Windows and Doors: With manufacturer of aluminum windows and doors, large or highly visible glass areas still need location-appropriate safety review; appearance and safety should be specified together.

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.
