Installation Instructions

TRIM & FASCIA 190, 440, 540 & 2000 SERIES
INSTALLATION
• Trim ends may lightly touch adjacent trim edges around windows and doors only. Seal all cut ends exposed to the weather.
• When installing trim around windows and over window anges, be sure to follow the window manufacturer’s installation
instructions.
• All openings must be properly sealed and ashed in a manner that prevents moisture intrusion or buildup. Flashing may be
sealed to the water-resistive barrier by using adhesive ashing or housewrap tape. (See ALL diagrams)
• When trim is installed adjoining vinyl siding, install Z-ashing with a 4 inch (102 mm) upper leg between horizontal trim and
utility trim or J-channel. (See diagram 8a)
• Horizontal trim or bands shall be ashed with a sloped metal Z-ashing to redirect water away from the wall assembly.
