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 (interior temperature and relative humidity and exterior temperature) are
present. When the formation of excessive 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 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 combinations during the shop drawing stage that result in bridging thermal breaks
of one or all products involved
