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 recommend ed 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 15 - General Notes and Guidelines

1. Below illustrates the recommended hardware locations for various unit config urations.

2. The exact lock locations and quantities will be determined on a job by job basis and will vary with the design pressure and vent configuration for a given project. Refer to the final approved shop drawings for quantities and locations. Snubbers at the vent head may not be required depending on structural loads and the size of the vent.

3. Opening limiting hardware is required for all vent installations. The maximum opening size for vents will be determined by local code, but may not exceed more than opening at a 20 degree angle normal to the plane of the wall for safety reasons.

Butt the gaskets together at the corners (see Figure 22). “Crowd” in extra gasket, (approximately 4% to 5% extra) where it runs between the gaskets to ensure a snug butt joint at the corners. It is important that there are no gaps in the gaskets where they meet in the corners. Note that the gasket is not symmetrical, and must be installed so that it is flush with the side of the mullions (see Figure 20).

5. A 3/8” backer rod should be applied into the isolator reglet to prevent sealant from getting into the reglet. Remove the backer rod immediately after the sealant is applied, and before the sealant begins to cure or skin over (See Figure 21).

6. Slide the WS00 vent surround gasket into the 17A6 adapters that will be applied to the intermediate horizontals above and below the concealed vent opening. Cut the WS00 gasket about 1/4” longer than the 17A6 adapter that will be applied at the head of the vent opening. Cut the WS00 gasket about 3” shorter than the 17A6 adapter that will be applied at the sill of the vent opening. See Figures 32 through 35 on page 26.

7. Roll the 17A6 adapter into the isolators in the intermediate horizontals at the head and sill of the vent opening. Crowd the WS00 gasket at the head between the vertical fin bar adapters as the adapter is inserted in place. Center the WS00 gasket in the opening at the sill of the vent opening.

8. Insert HS32 setting blocks between the 17A6 adapter at the head of the vent opening and the upper lite of glazing at quarter points or as directed in the final approved shop drawings. See Figures 32 through 35 on page 26.

Section 22 - SSG Vent Unit Glazing at Fixed Horizontal : D. Weather Seal Application

1. Using an approved solvent or cleaner, clean the sealant contact surfaces of the glazing and adapters of all oils and other contaminants.

2. If sealant primer is required, apply it per the primer/sealant manufacturer’s instructions.

3. Insert 3/8” diameter backer rod between the glazing and adapters around all four corners of each lite of glazing. Refer to Volume 2, Figure 38 page 17 for more information.

4. Apply sealant into the void between the adapters and glazing to form the weather seal and tool smooth. If the sealant is properly and carefully applied, masking tape on the adjacent surfaces is not necessary.

5. Seal the ends of adapter at the head of the vent, running the sealant to the face of the vertical, but not across the face of the vertical. This allows weeps for the glazing pocket of the lite above the vent. Tool the sealant neatly into the adjacent surfaces. Slide the WS00 gasket out of the way to apply this seal. Return WS00 to its former position after sealing. See Figure 38.

6. Seal the ends of the adapter at the sill of the vent, running the sealant to the vertical and across the face and around to where the adapter meets the horizontal. Lift WA07 gasket out of the way to apply this seal. Tool the sealant neatly into the adjacent surfaces. Return WA07 to its former position after sealing. See Figure 39.

7. Before the sealant begins to cure or skin over, tool the sealant into the joints smoothly, taking care to smooth and blend the sealant in the corners and intermediate intersections as shown below.
