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 7 - Outside 90° Corner Unit Frame Assembly : A. Mullion Subassembly

1. Assemble anchor kits by screwing in the M170 set screw into the bottom of the FM07 mullion anchors until the set screw is flush with the bottom of the

anchor. (Left and Right Hand Assemblies Required)

2. Slide the FM05 or FM06 hook anchor into the FM07 mullion anchor as shown in Figure 1 and 2. See END VIEW on page 6 for part orientation.

3. For the dead load anchor, screw a M169 hex head bolt into the top of the FM07 mullion anchor, half way into the anchor so that 1 3/4” of the bolt extends

from it. See Figure 1 below. For the wind load anchor, screw a M170 socket set screw in the top of the anchor, flush with the top of FM07 as shown in Figure 2, below.

Section 7 - Outside 90° Corner Unit Frame Assembly : A. Mullion Subassembly

4. Apply the mullion anchor assemblies to the unit

corner mullions (KV09 and KV10). Insert (3) bolts (3/8”-16 x 4 1/2” HX-MS 18-8) through the anchors and mullion.

5. Use right and left hand corner anchor assemblies

to orient the tops of the anchors and mullion as shown and noted in Figures 3, 4 and the END VIEW, and insert the bolt through the anchors and mullion.

6. Secure the anchors with (3) 3/8”-16 nylon insert

stop nuts (M172).

7. Apply shear blocks (KV11) for the intermediate horizontals to the unit corner mullion with (4) SM00 (1/4" -10 X 3/4 SL-HW-SMS ZC A) at each intermediate

horizontal location.

8. Once the shear blocks have been attached with SM00 fasteners, adjust the shear blocks so that the face of the horizontal aligns with the face of the corner

mullion. Using a mitered, short piece of horizontal as shown in Figure 7 will aid with alignment. The shear blocks have (4) adjustment slots and (1) fixing hole for adjustment and to lock them into position (see Figure 10).

9. Lock the shear block in place with (1) STK3 alignment screw (#12-14 X 3/4” HW-SMS 410 TEK 3) at each interme diate horizontal location (see Figure 9).

10. Using an approved solvent or cleaner, clean the sealant contact surfaces of the mullions and shear blocks of all oils and other contaminants.

11. Apply a generous amount of silicone sealant around the front part of the shear block as shown in Figure 11. Apply a generous bead of silicone sealant

around the front part of the intermediate horizontals as shown in Figure 12. Apply sealant to the mitered end only.

Align face of mullions.

12. Insert the horizontal onto the shear block and attach with (7) STD0 (1/4”-10 x 1” PL-FH-SMS 18-8 AB) fasteners per shear block. Note: The number and

locations of fasteners may vary. Remove all excess sealant from areas that will be exposed to the interior. See Figures 13, 14, and 15.

13. Remove excess sealant from gasket reglets and areas where the isolator clips and adapters will later be inserted. See Figure 15.

14. Cap seal the fastener at the face of the horizontals as shown in Figure 16.
