A170/A200/A250 - Drip Trim
TheAtypetrimisadriptrim,ttedtothelowestedgeoftheroofusuallywheretherainwater
owsintothegutter.Twosupportbattensshouldbexedtotheperimeteroftheroofto
providespacefortheguttertotbehindthetrim,withtheouterbattenattached10mmlower
thantheinnerbattentoallowthetrimtositushwiththeroof.Applyadhesivetothebatten
in a continuous strip then rub the trim into place and nail to the decking. Do not nail through
the front of the trim. If the pitch of the roof is only minimal, rainwater is likely to hold behind
the trim. A planing machine can be used to take 2mm off the deck to allow the trim to lay
ushwiththeboard.
TRIM DETAILS: A170: This is designed for applications where it is not possible to use the
larger A200. A200: This is the standard size drip trim. A250: This drip trim is ideally suited for
use on warm roofs.
