7.7 General Information on Flashings and Trims
7.7.1 Roof Edges / Drips /Trims – Mechanically Fastened System
Whenever possible, external roof edges shall be constructed using
Monarplan® Coated Metal.
Separate lengths of the Monarplan® Coated Metal drip trim are
butt jointed. The sheets should be fastened with two rows of
fasteners, typically screws, at 150 mm staggered centers. A 5 mm
gap should be left to allow for expansion of the metal.
The joints should then be taped with a 50 mm wide duct or crepe
tape.
The joint should then be strapped with 150 mm wide Monarplan®
D Unreinforced Flashing, hot-air welded to the coated metal with
a 20 mm weld.
Depending on the construction detail, the edge of the roof
should be made air-tight. A strip of suitable sealant should
be installed along the edge beneath the coated metal. If a
compatible vapour control layer is specified, then the vcl can dress
up onto the timber edge batten, and again, be terminated with
a strip of sealant. Consult Icopal’s standard drawings for further
