METHODS OF GLAZINGDOUBLE GLAZING THE INSTALLATION OF TWO PARALLELPANES OF GLASS WITH A SEALED AIR SPACEBETWEEN TO REDUCE THE TRANSMISSION OFHEAT AND SOUND.FACE GLAZING THE SETTING OF A GLASS PANE IN ARABBETED FRAME, HOLDING IT IN PLACE WITHGLAZIER’S POINTS, AND SEALING IT WITH ABEVELED BEAD OF PUTTY OR GLAZINGCOUMPOUND.
  • 13. • PUTTY- A COMPOUND OF WHITING AND LINSEED OIL, OF DOUGHLIKE CONSISTENCY WHEN FRESH, USED IN SECURING WINDOWPANES OR PATCHING WOODWORK DEFECTS.• FACE PUTTY- THE PUTTY OR GLAZING COMPOUND FORMED ON THE EXTERIOR SIDE OF GLASS AN EVEN BACKING.• BEDDING- A THIN LAYER OF PUTTY LAID IN THE RABBET IN A WOOD SASH TO GIVE A PANE OF GLASS AN EVEN BACKING.• GLAZIER’S POINT- A SMALL, POINTED PIECE OF SHEET METAL FOR HOLDING A GLASS PANE IN A WOOD SASH UNTIL THE FACE PUTTY HAS HARDENED.
  • 14.  WET GLAZING THE SETTING OF GLASS IN A WINDOWFRAME WITH GLAZING TAPE OR A LIQUIDSEALANT. GLAZING TAPE-A PERFORMED RIBBON OF SYNTHETIC RUBBER HAVING ADHESIVE PROPERTIES AND USED IN GLAZING TO FORM A WATERTIGHT SEAL BETWEEN GLASS AND FRAME. CAP SEALANT-AN ADHESIVE LIQUID OR SYNTHETIC RUBBER INJECTED INTO THE JOINT BETWEEN A GLASS PANE OR UNIT AND A WINDOW FRAME, CURING TO FORM A WATERTIGHT SEAL. GLAZING BEAD-A WOOD MOLDING OR METAL SECTION SECURED AGAINST THE EDGE OF A GLASS PANE OR UNIT TO HOLD IT IN PLACE.
