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 unfavorabl e cond itions (interior temperature and relative humidity and exterior
temperature) are present. When the formation of excessive condensation is a concern, it is highly recomm ended 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 lik ely to occur:

1. Bridging system thermal break with non-thermally broken metal flashing or lintels th at 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

Note: Assembly Instructions are provided as a supplement, and should be used in conjunction with

the approved shop drawings.

Section 33 - Shadow Box Assembly

1. Assemble the unit frame as shown in Volume 1 of Series 8700 / 8800 Unitized Curtain Wall Assembly Instructions, through “Section 3 - B. Unit Frame
Assembly”. For reduced handling for units with shadow boxes, assemble the unit frame with the interior side facing upward.

2. Clean the ends of the shadow box framing members where sealant will be applied with an approved solvent or cleaner.

3. Seal the ends of the shadow box frame members with sealant. See Figure 2.

4. Assembly the shadow box frame with (8) SLQ5 fasteners. Remove excess sealant from the outside areas of the frame corners.

5. Cap seal the fastener heads, seal inside the frame corners, and frame screw splines in the corners of the frame. Tool the sealant carefully to make water
tight. See Figures 3 and Figure 4.

Seal ends of shadow box
frames before assembly.
