05 · Planning knowledge
Answers organized around real specification questions.
Frequently asked questions remain readable on the page and are also provided as structured FAQ data.
Which values are binding for AWS 75.SI+?
Only the values of the specifically engineered and verified unit configuration are binding, including profiles, size, opening type, glazing, hardware, anchoring and installation interface.
Which glazing can be used?
The published system range is 18–61 mm. A specific glass build-up also depends on size, weight, sash dimensions, hardware and structural verification.
Is to RC 3 automatically included?
No. A resistance class only applies to the tested assembly of profiles, hardware, glazing, anchoring and installation. The required class must be specified for the project.
How is the binding whole-window U-factor determined?
From the frame share, Uf value of the actual profile combination, glazing Ug value, glass-edge length, spacer Ψ value and, where applicable, mullions, transoms and special geometry.
