General Procedure for the Installation of Window Units
in Masonry Openings Without Subframe or Panning
The glazing bead may require removal
and reinstallation. Care must be
exercised to avoid damaging the glazing
beads. (Always remove beads that run
between first).
To remove the glazing bead, apply
pressure to the inside lower bead edge
and compress the glazing vinyl. (See
arrow one). While maintaining pressure,
give a slight upward movement. If the
bead is really tight, it may be necessary
to insert a putty knife in the crevice
between the bead and frame giving a
slight twisting motion as pressure is
applied to the bead.
Drilling of frame and blocking by erector.
Field notching of glazing beads maybe
required to clear fastener heads before
reinstallation of beads.
EFCO Corporation will not be held
liable or accept responsibility for
damage to the glazing beads, window
finish, or broken glass, which is a result
of this type of installation.
