7.2.4 Moisture detection (2): Commercial & residential façades
7.2.4.1 General information
Thermography has proven to be invaluable in the assessment of moisture infiltration
into commercial and residential façades. Being able to provide a physical illustration
of the moisture migration paths is more conclusive than extrapolating moisture meter
probe locations and more cost-effective than large intrusive test cuts.
7.2.4.2 Commented building structures
This section includes a few typical examples of moisture problems on commercial
and residential façades.

Pelting rain penetrates the façade due to badly
executed bed joints. Moisture builds up in the
masonry above the window.

Pelting rain hits the window at an angle. Most of
the rain runs off the window edge flashing but
some finds its way into the masonry where the
plaster meets the underside of the flashing.
