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 centres. 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®

a 20 mm weld.

strapped with Monarplan® Reinforced Strip and hot-air welded
with a min 20 mm weld to finish the seal.
