🧪 ASTM C1401 (Structural Bite B = [0.5 x Wind x Span] / 20 PSI Design Stress)

Structural Silicone Glazing (SSG) Calculator

Size structural silicone joint bite width and glueline thickness bonding glass panels to aluminum curtain wall frames under ASTM C1401: calculate required structural bite (B = [0.5 x Wind Load PSF x Short Span Ft] / 20 PSI allowable dynamic design stress, minimum 1/4" to 3/4"), calculate silicone sealant volume and adhesive cures, and facade engineering margins.
