non-hardening type of sealant. Refer to the approved shop drawings for joint design.

6. Perimeter Anchorage
A. From the approved shop drawings, determine the size, type, and quantity of perimeter
fasteners required. EFCO will provide fasteners for EFCO material to EFCO material only. All
perimeter fasteners are Not by EFCO and should be purchased prior to arriving at the job site.
(If Subframe is used, please refer to the Subframe installation sheets.)
Due to varying opening conditions, window configurations, design pressures, and methods of
anchorage (subframe, “F” anchors, etc.), perimeter fasteners are not specified in these
instructions. For perimeter anchor type and spacing, refer to the approved shop drawings or
consult the project design professional. The design professional should analyze the
anchorage system, and take into account the following information.
1. Frame dimensions and configuration of the as-installed window.
2. Material properties of the window frame.
3. Allowable tension, shear, and bending properties of the perimeter fastener.
4. Design pressure.
5. Details of the surrounding condition for the head, sill, and jambs.
6. Relative building movements and expected thermal movement of the window system.

These recommendations are for general erection procedures only. For actual job
conditions, see the details on the shop drawings. For perimeter anchor type and spacing,
refer to the approved shop drawings or consult the project design professional.
