1. For a glazing ratio smaller than 1:1.8 see “Table 10. Flat, 2 Sides Clamped PALSUN Load Chart”.
2. Glazing table begins with 4mm (5/32”)thickness as the lowest thickness recommended for permanent quality glazing.
Thinner sheets fit signs, advertising, vacuum-forming, agricultural structures, temporary pavilions etc.
