Permatherm EPS Maximum Spans for Uniform Loads

Uniform Load Spans are rounded to the lower footage.* All values are calculated using core material of Type 1 (1 lb. Density) EPS Foam. Greater values can bereached with higher density foam which is available.Other GuidelinesPermaTherm Architectural Insulating Panels are designed to carry specified total loads, with maximumcomputed 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 exteriorskin.Wherever interior panel skins are extended to the outside (warm side) surface, a thermal break must be cutto avoid thermal conductivity.Block panel packages should be stored above ground to keep out of water provide drainage.
