Insulation Panel Structure

Insulated panels are integral units in which the insulation layer together with the two metal skins act as a beam to resist wind and point loads. The bonded insulation core material contributes to the panel's strength by effectively increasing the web depth of the profile and resisting buckling; the depth of the core largely determines the panel's resistance to deflection. Panel stiffness is also affected by skin thickness and profile shape.

Insulated panels are excellent at supporting normal foot traffic without damage because the foam core provides continuous support to the external sheeting. The number and strength of the fasteners under wind suction loads can limit the maximum purlin spacing.
