Audit rules
VentTools does not invent installation positions. It separates nominal duct size, casing or frame geometry, tested aperture, lining and structural opening. Any unresolved conflict remains visible or disables the affected calculator.

This is an engineering database beta for regression testing. The current manufacturer IOM, Declaration of Performance, project fire strategy and approved supporting construction remain controlling.
