Three independent technical lenses are relevant to aluminum door frame manufacturers: 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 — 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 aluminum door frame manufacturers review, this source is being used to frame the opening-specific check rather than to supply a DAW product value.
Connection to Aluminum Door Frame Manufacturers: The connection to aluminum door frame manufacturers is the joint map: identify which gaps never move and which cycle with the opening, then detail and maintain them accordingly.

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. On this aluminum door frame manufacturers page, the point is translated into a drawing question so the technical context stays connected to the actual opening.
Connection to Aluminum Door Frame Manufacturers: The project link is installation quality: sealant joint width can affect uncontrolled air movement even when the glass package itself is well selected.

U.S. Access Board — Accessible Doorway Guidance
Source summary: The guidance links clear passage, threshold conditions and maneuvering space to the real door geometry. That is important because nominal frame width does not by itself describe the space available to a user. For the aluminum door frame manufacturers review, this source is being used to frame the opening-specific check rather than to supply a DAW product value.
Connection to Aluminum Door Frame Manufacturers: The link to aluminum door frame manufacturers is practical: replacement tolerance must be verified after panel/leaf movement is accounted for, otherwise the scheduled width can overstate usable passage.

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.
