I_eff Calculator for Thermally Broken Profiles [ EN 14024 Annex C ]

According to EN 14024, the effective moment of inertia (I_eff) of a thermally broken profile is computed by considering the shear-flexibility of the thermal barrier. The result represents the real stiffness used in strength and deflection checks.

For safe design, professional engineering verification is essential. For details and support, please contact your facade consultant.
