ENVELOPE SYSTEMS/EIFS
Foundations
The detail shown in Figure 4.7.6, or a variation of it, is commonly used to protect the ground-level
insulation of the EIFS cladding from punctures and other damage. Although damage to the
cladding is reduced, this system results in a significant thermal bridge below the insulation.
Alternatively, the modified detail shows a continuous layer of insulation all the way down the wall,
with the lamina carried below grade to protect the insulation. It is recommended that this alternate
approach be used and some other means be used to keep the public and building staff from getting
too close to the building facade. Pavers will protect the insulation from damage due to landscaping
activities.
