Thermal bridge

A stationary thermal bridge and a wind-sensitive leak can feel similar, but temperature shape and air movement separate them.

A conductive junction and limited air movement create a colder interior surface where moisture can condense.

Air movement within or through a wall bypasses insulation and creates localized cold surfaces.

Differential support or movement redistributes stress around openings and finishes.

Pipe length changes during warming and cooling, producing repeated frictional releases at penetrations and clips.

Wood moisture and temperature cycles move framing enough to crack a weak finish joint without foundation failure.

Heat flows through a concrete perimeter with limited insulation, creating a repeatable cold strip inside.

A cold surface and a moving draft can feel similar but require different checks.

Outdoor air moves through or over low-density insulation, cooling the ceiling edge and altering attic moisture patterns.
