Please note that the placement of individual bases must be reviewed by a Structural Engineer to ensure that the roof structure is not overloaded.

Based on a factor of safety of 2 against published minimum ultimate values of insulation compression strength
(NRCA Commercial Low-Slope Roofing Materials Guide, 1994 Edition). Designer must also ensure adequacy
against punching resistance and overall structural integrity of the roof on which the assembly is placed.
Resultant stresses from lateral loads on pipes may result in higher stresses in substrate than plain gravity loads.
