Other Manufacturing Guidelines
PermaTherm Architectural Insulating Panels are designed to carry specified total loads, with maximum
computed buckling stress not to exceed the maximum allowable buckling stress of the facings.
The inside face of all panels must be cut at girt attachments to avoid compression bucking of the exterior
skin.
Wherever interior panel skins are extended to the outside (warm side) surface, a thermal break must be cut
to avoid thermal conductivity.
Block panel packages should be stored above ground to keep out of water, and on a sloped surface to
provide drainage.
