TABLE 10.2 Common Envelope Movement Causes
Movement Cause
Thermal Expansion or contraction movement caused by temperature changes
Structural Caused by the curing process of concrete during settlement or structural
loading of the building
Differential Materials have individual coefficients of movement, which will differ from
surrounding materials, causing differences in movement between the
materials
Moisture content Certain materials, particularly masonry, swell when subjected to wetting;
this movement or enlarging, when calculated as an aggregate total of the
entire facade area, can be considerable
