Installation Guide

Store LP TechShield panels in a clean, dry area. Do not store in
direct contact with the ground. Protect from moisture prior to and
during installation. Outside storage, if necessary, requires panels
to be covered with plastic sheets or tarpaulins with the sides
loosely covered to provide adequate air ventilation.
Handle LP TechShield panels as you would other APA rated LP
sheathing products. Be careful not to drop on corners or crush

contribute to the reduction in solar gain and the overall energy

TechShield sheathing on roofs, it is important that it is installed
with the foil side facing into the attic.
