Corner Release Paper Removal Guide for ALTERNATIVE
METHOD described on page 8
Use the following guide to create a template to aid in removal of the release paper
from the corner section only. This will assist in creating the 90° fold between the
two release papers.
Align the bottom edge of 6" DuPont
™
FlexWrap
™
NF with the the 2" marks (for up to 2"
recess). Align the bottom edge of 9" FlexWrap
™
NF with the lower edge of the template
(for recesses greater than 2").
For best results, create a reusable template using a piece of heavy/rigid plastic. The
template can also be used as a guide when tearing the release paper. Otherwise, use
the template to mark the release paper and then use a metal straight edge to assist in
tearing the release paper. Do not cut the release paper with a knife or other sharp
object as this could result in damage to the butyl and compromise protection provided
by the FlexWrap

NF Recessed Window Corners.
