Is it true that air pressure differs between the inside and outside of a house due to thermal and ventilation gradients?

Yes. Air pressure indeed differs between the inside and outside of a house driven by thermal gradients and ventilation factors, widely studied as the stack effect.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked

The analysis

The claim is specific, empirical, and testable. The retrieved papers [0], [2], and [11] explicitly analyze indoor-outdoor pressure differences driven by thermal and stack-effect phenomena in buildings. There are no papers contradicting this established building-physics principle.
