To install shutters around windows:
- Pre-drill holes through the shutters for attachment screws and mark the location of these holes on the siding (Fig. 74).
- Using the hole marks as a guide, drill expansion holes through the siding where attachment screws will be located, a minimum 1/4” (6.4mm) larger than the diameter of the screw (Fig. 75).
- When attaching the shutters, do not fasten such that the shutter is tight against the siding, otherwise expansion of the siding will be restricted.
- When it is necessary to attach any specialty item, for example down spouts, drill a hole that is 1/4” (6.4mm) larger than the fastener shank diameter to allow the vinyl panel to move with temperature changes.
