Minimizing Condensation
Note: Please reference EFCO's "Understanding Condensation" brochure which can be obtained
through your EFCO representative.
Condensation will form on any surface when unfavorable conditions (interiro temperature and
relative humidity and exterior temperature) are present. When the formation of extensive condensation
is a concern, it is highly recommended that a design professional is utilized to perform an analysis of
the shop drawings to recommend the best possible installation methods. Please contact your EFCO
representative for information on EFCO's Thermal Analysis Services.
Many current installation practices lead to an increase in the possibility of the formation of
condensation. Though not all inclusive, the list of examples below illustrates conditions under which
condensation is likely to occur:
1. Bridging system thermal break with non-thermally broken metal flashing or lintels that
are exposed to the exterior
2. System exposure to the cold air cavities
3. Interior relative humidity levels not maintained at recommended levels, see EFCO's
"Understanding Condensation" brochure
4. Inadequate separation between system and surrounding condition at perimeter
5. Product conbinations during the shop drawing stage that result in bridging thermal
breaks of one or all products involved
