2. INTRODUCTION
SRUCTURAL GLAZING IS A SRTUTURAL
MEMBER WHICH INCLUDES GLASS UNITS,
GENERALLY FOR FACADE WORK.
1. IMPROVE THE COMFORT AND
PERFORMANCE OF BUILDING
OCCUPANTS.
2. ASSIST IN NATIONAL AND GLOBAL
EFFORTS TO REDUCE GREENHOUSE
GAS EMMISIONS THAT CONTRIBUTE TO
GLOBAL WARMING.

 GLAZES HAVE BEEN
DISCOVERED TO HAVE BE IN THE
DECORATION OF AS FAR BRICKS
AS EGYPTIAN PERIODS.
 PERHAPS THE EARLIEST
EXAMPLE OF SRUCTURAL
GLAZING IS GLASS BLOCK
DEVELOPED IN EARLY 1900S TO
BRING MORE LIGHT IN
INDUSTRIAL SPACES.
HISTORY OF
SRUCTURAL GLAZING

4. 4
STRUCTURAL GLAZING IS A
SYSTEM OF BONDING TO AN
ALUMINIUM FRAME UTILIZING A
HIGH PERFORMANCE SILICONE
SEALANT.
THIS TECHNIQUE CAN BE USED
WITH ALMOST ALL TYPES OF
GLASS, INCLUDING INSULATING
GLASS UNITS.

GLASS - 100 % RECYCLABLE
MATERIAL
ALUMINIUM – LESS WEIGHT, BUT
HIGH STRENGTH
SILICONE SEALANT – SAND GEL
USED FOR BONDING GLASS
EPDM – ETHYLENE PROPYLENE
DIAMINE MONOMER
TO PREVENT WATER AND
AIR ENTERING.

ACCESSORIES FOR STRUCTURAL
GLAZING
MULLIONS ( VERTICAL MEMBER ) :
MULLIONS ARE PROVIDED BASICALLY TO TRANSFER THE LOAD OF THE CURTAIN
WALL.
TRANSOMS ( HORIZONTAL MEMBER ) :
TRANSOMS ARE ALUMINIUM SECTIONS PROVIDED IN BETWEEN THE MULLIONS
HORIZONTALLY.
SILICONE SEALANTS :
SILICON SEALENTS ARE USED TO PREVENT THE PASSAGE OF MOISTURE, AIR, DUST
AND HEAT THROUGH ALL THE JOINTS.
SETTING BLOCKS :
SETTING BLOCKS ARE USED TO PROVIDE SUPPORT IN THE RELATION TO THE SIZE
OF GLASS, GLAZING TECHNIQUES AND CONDITIONS OF USE.
LOCATION BLOCKS :
EDGES OF GLASS, TO PREVENT THE MOVEMENT OF THE GLASS WITHIN THE
FRAME.

COMMONLY USED INNOVATIVE
GLAZING SYSTEMS ARE -
BOLTED GLAZINZG
FIN SUPPORTED
GLAZING
CABLE STAYED

10. 10
LESS OBSTRUCTIVE
ALTERNATIVE TO SRUCTURAL
GLAZING
THIS TRADITIONAL SYSTEM CONSIST
OF ATTACHING THE GLASS PANELS
AND THE SRUCTURE WITH THE RIGID
BOLTS AND STEEL PLATES.
MODERN BOLTED SYSTEMS USE
KNUCKLED BOLTS FOR FIXING OF
THE GLASS, INSTEAD OF THE
COMMON FIXED BOLT.
BOLTED GLAZING

BOLTED GLAZING

12. 12
o A GLASS FIN REPLACES A
FRAME OR MULLIONS
o THE REACTION LOAD IS
TRANSFERRED TO TOP AND
BOTTOM OF THE FIN SHOE.
o FIN SYSTEMS ARE ALSO
DESIGNED WITH BOLTED JOINTS
o IT CREATE GRATER VISIBILITY
AND INCREASE THE NATURAL
LIGHT IN INTERIORS.
FIN SUPPORTED
GLAZING

13. 13
FIN SUPPORTED GLAZING

14. 14
CABAL SUPPORTED GLAZING
SYSTEM IS LIKE FIN SUPPORT
SYSTEM ARE ALSO INCREASINGLY
USED.
CABLE SYSTEM CREATS GREATER
LEVELS OF OPENNESS, VISIBILITY
AND NATURAL LIGHT AND INHANCH
THE DRAMATIC APPERANCE OF THE
BUILDING.
IN THIS SYSTEM, STAINLESS STEEL
OR CARBON FIBER HIGH STRENGTH
CABLES ARE USED TO TRANSFER
LOAD TO MAIN STRUCTURE.

SPIDER SYSTEM
 SPIDER SYSTEM IS A SYSTEM FOR POINT
SUPPORTED VERTICAL GLAZING IN WHICH
THERMALLY TEMPERED GLASS SHEETS ARE
USED, IN SINGLE GLAZING OR IN INSULATED
GLAZING.
 THIS SYSTEM IS SUITABLE FOR NEW BUILD
AND IA ESPECIALLY EFFECTIVE FOR THE
REFURBISHMENT OF OLD BUILDINGS.
 APPLICATIONS :
• HUGE BUILDING AND SHOP FACADES
• LOBBIES, PASSAGEWAYS AND GLASS HOUSES
• SKYLIGHTS AND DOMES
• WALLS, INTERIOR PARTITIONS AND INTERNAL
STAIRCASES
• INTERIOR DESIGN

ADVANTAGES OF STRUCTURAL
GLAZING
INCREASES AMOUNT OF NATURAL LIGHT, LOWERS ELECTRICITY BILL.
ENVIRONMENT FRIENDLY AND 100% RECYCLABLE
FREE FROM CORROSION
LONG LASTING
PROTECTION FROM WEATHER DAMAGE
ASTHETIC LOOK, VISUALLY APPEALING
FLEXIBLE INFRA-SRUCTURE

22. 22
DISADVANTAGES OF STRUCTURAL
GLAZING
 IT IS EXPENSIVE AND MAY INCREASE THE BUDGETED
COST OF CONSRUCTION WORK.
 HIGH MAINTAINANCE
 UNSAFE IN EARTHQUAKE SITUATIONS.

31. 31
AS CURTAIN WALL IS NON-
STRUCTURAL CAN BE MADE OF A
LIGHT-WEIGHT MATERIAL
REDUCING CONSTRUCTION
COSTS.
WHEN GLASS IS USED AS A
CURTAIN WALL, A GREAT
ADVANTAGE IS THAT NATURAL
LIGHT CAN PENETRATE DEEPER
WITHIN THE BUILDING.

STRUCTURAL GLAZING CURTAIN WALL
 SRUCTURAL GLAZING IS A
STRUCTURAL MEMBER, WHICH
TRANSFERS LOAD FROM TOP
TO BOTTOM BY GLASS.
 IT HAS LONGER SPAN.
 AS IT WORK AS STRUCTURAL
MEMBER, LOADS ARE
CONSIDERED WHILE
DESIGNING.
 CURTAIN WALLS ARE NON-
SRUCTURAL MEMBER WHICH
DOESN’T TRANSFERS LOAD.
 IT HAS SHORTER SPAN.
 AS IT IS NON- SRUCTURAL
MEMBER NO LOADS ARE
CONSIDERED WHILE
DESIGNING.
