TERRASTILE DOOR INSTALLATION INSTRUCTIONS
E. Perimeter Anchorage
1. 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.
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.
a. Frame dimensions and configuration of the as installed door.
b. Material properties of the door frame.
c. Allowable tension, shear, and bending properties of the perimeter fastener.
d. Design
pressure.
e. Details of the surrounding condition for the head, sill, and jambs.
f. Relative building movements and expected thermal movement of the door system.
2. Perimeter anchors should never penetrate a tank or tubular shape at a sill. Any penetration
of the frame must be visible for sealing purposes.
3. Blocking must be of sufficient size and shape to support the frame at all anchorage
locations. The blocking must prevent the anchorage fasteners from bowing, racking,
twisting, or distorting the frames and accessories in any manner. Excessive shim heights
could increase the prying tension and/or bending forces on the perimeter fastener. Refer to
the approved shop drawings and/or design professional for project specific applications.
