Glazing Guidelines

General guidelines:

  • All architectural glass should be glazed in a way that ensures that it is free floating and non-load bearing. The glazing material must remain resilient.
  • To prevent premature failure of fabricated, opacified spandrel and laminated glass , an adequate weep system is necessary, or materials that totally repel the passage of water.
  • Adequate clearance must be provided for bow and warp of heat-strengthened and tempered glass, as specified in local approved standards such as NBR 7199 – glass in architectural application ; NBR 14698 – tempered glass; NBR 14687 – laminated glass; NBR 16015 – insulated glass and ASTM Standard C-1048 as reference.
