PREPARATION
Preparation, unless otherwise specified or approved, shall conform to
applicable recommendations in the GANA Glazing Manual, GANA Sealant Manual,
SIGMA TB-3001, SIGMA TM-3000, and manufacturer's recommendations.
Determine the sizes to provide the required edge clearances by measuring
the actual opening to receive the glass. Grind smooth in the shop glass
edges that will be exposed in finish work. Leave labels in place until the
installation is approved, except remove applied labels on heat-absorbing
glass and on insulating glass units as soon as glass is installed. Securely
fix movable items or keep in a closed and locked position until glazing
compound has thoroughly set.

windows may be glazed in conformance with one of the glazing methods
described in the standards under which they are produced, except that face
