Edge Strip
Hook the lower edge of fascias at least 20 mm 3/4 inch over a continuous
strip of the same material bent outward at an angle not more than 45
degrees to form a drip. Nail hook strip to a wood nailer at 150 mm 6 inches
maximum on centers. Where fastening is made to concrete or masonry, use
screws spaced 300 mm 12 inches on centers driven in expansion shields set
in the concrete or masonry. Where horizontal wood nailers are slotted to
provide for insulation venting, install strips to prevent obstruction of
vent slots. Where necessary, install strips over 2 mm 1/16 inch thick
compatible spacer or washers.

Joints
Leave open the section ends of gravel stops and fascias 6 mm 1/4 inch and

concealed splice plate 150 mm 6 inches minimum. Join the gutters, other
than aluminum, by riveted and soldered joints. Aluminum gutters shall be
joined with riveted sealed joints. Provide expansion-type slip joints
midway between outlets. Install gutters below slope line of the roof so
that snow and ice can slide clear. Support gutters on [adjustable hangers
