Editorial interest 84/100 Selection signal · not a rating of the site

A tightly organized register of window and facade assemblies, the standards used to test them, and the revisions that record what changed.

Landing page captured for the 2026-09-18 issue.

For: Facade designers, window engineers, and building-envelope reviewers
Worth noticing: Seven tests connect assembly details to standards, measurements, revisions, and field-failure records.

Field notes

The site uses a drawing-sheet structure rather than a conventional article layout: numbered entries, title blocks, revision letters, issue dates, and cross-linked source material. Its component register covers details such as a 16 mm argon cavity, spacer-bar conductivity, drainage-path area, solar-control SHGC, and airtightness q50. Test sheets turn those details into procedures, while the field-failure entry specifies five data fields and four photographs.
