Section 8 - Setting Units at Static Starter Sills
1. Static starter sills are used with installations that don’t require provisions for vertical movements at the beginning floor of the curtain wall.
2. Units are typically installed from left to right from as seen from the exterior of the building. Install each frame unit in sequence, starting at the left jamb unit.
3. Units are lifted by the splice bars attached at the head of each unit. These bars are also used to align the units when stacked vertically.
4. Ensure the HC07 caulk backer has been inserted into the sill as shown in Figures 62 and 64 on page 31. Note that jamb units will receive HC07 on both
ends of the sill. Subsequent units will require HC07 on the right end only of the unit sill as viewed from the exterior.
5. Lower the jamb unit down into position onto the starter sill. The hook anchors should also be hooked onto the slab anchors. The unit should now be setting
hard on the starter sill. See Figures 66 and 67.
6. Installations utilizing the static starter sill must use a wind load anchor at the first floor above the starter sill as shown in Figures 68 and 69. All consecutive
floor slabs above the wind load anchor will be the typical dead load anchor as shown in “Section 10 - Setting Typical Intermediate Units”.
7. Place a shim pack between the jamb mullion and the condition to prevent the jamb unit from shifting when setting successive units.
