TRIM & FASCIA 190, 440, 540 & 2000 SERIES
APPLICATION
INSTRUCTIONS
• Trim must extend beyond the face of the siding. Trim may be installed
directly to the sheathing, or directly over the siding.
• Horizontal trim: properly integrate ashing with siding, WRB and
vertical trim. At corners, allow the end of the trim to overlap the end of
the adjoining trim. Leave a 3/16 inch space and seal with sealant.
(See diagram 6a)
• Vertical corners directly to sheathing: allow for proper spacing
between the trim edge and siding. Corner trim edge may lightly touch
adjacent trim edge. Follow siding manufacturer’s application
instructions. (See diagrams 6b and 6c)
• Vertical corners over siding: the width of the trim must overlap the
siding by a minimum of 2 inches. Sealant between the trim and siding is
not required for this application. Allow for proper spacing at the corner
between perpendicular siding pieces. Corner trim edge may lightly touch
adjacent trim edge. Follow siding manufacturer’s application
instructions. (See diagram 6d)
• OPTIONAL Pre-assembled vertical corners: cut vertical corner pieces
to size with clearance requirements in mind. Set perpendicular corners
pieces and pre-drill fastening holes a minimum of every 24 inches o.c.
Fasten into pre-drilled holes with proper nails or screws.
