FIN DESIGN & DETAIL
DETAILSFINMinimum design requirements are:Fins should always be mechanically fixed to the structure by means of a back to back steel or stainless steel fin bracket ;Structural fins should not be less than 12mm in thickness and should always be toughened
Internal entries When the width of the sidelite (A) plusthe height of the highlite (B) exceeds a total of 1000mm a structural fin is required External entries A wind load design should always be carried out to determine thickness and width of fin.

Glass fins in most cases must run the full length of the panel height and be channel glazed or mechanically secured depending on the application.
FIN SUPPORTWith full height fin designs, (X) must be no less than 2/3 of the fin width required.

FIXING OF GLASS WALLSChoose the right glass block for your project.Draw a diagram of the installation.Mix the glass mortarPut down a bed of mortar and place the first row of blocks.Place the appropriate spacers between the blocks.Install anchors and reinforcing rods every 2 feet (30 cm) to provide strength and stability to your glass block installation.Tool the jointsClean any stray mortar off the faces of the blocks with a damp cloth.Seal the perimeter and joints when the mortar is completely set
FRAMELESS SHOWER SCREENSFrameless toughened safety glass can provide an alternative to standard aluminium framed shower screens. National Glass can supply shower door options as shown.Minimum recommended thickness should be 10mm toughened safety glass.FIXING METHOD:The recommended method is to mechanically fix the glass with special bolt through plated brass or stainless steel angle bracketsA second method is to use an aluminium or plated brass U channel which is screw fixed to the wall and floor and the glass is fixed into the channel using structural grade silicone.MAXIMUM SHOWER DOORWIDTH/HEIGHT

DIFFERENT WAYS OF ARRANGEMENT
GLASS FLOORINGusually a multi-laminated glass made-up of 23 panels of annealed glass one panel of 6mm toughened glass non slip coating to the trafficable surface.The coating is ceramic fired paint for durability and wear.
INSTALLATION DETAILS It is recommended that the glazing block shall have shore hardness 80 to 90;The joints between the floor panels and structure shall be 6mm minimum;It is recommended to use Dow Corning for the sealants around the floor panels;The recommended support width for the floor panels shall be 20mm minimum;Maximum allowable deflection in support framing is span over 500.
STANDARD NON SLIPPY SURFACE PATTERN
WHAT NBC SAYS?Safety Glass Safety glass shall be of four types as follows:a) Toughened Safety (Tempered) Glass (TS)b) Toughened Float Safety Glass (TF)c) Laminated Safety Glass (LS)d) Laminated Float Safety Glass (LF)Glass at b and d shall be preferred.Critical Locations:Where there is danger of falling infill glassmaterials from overhead glazingb) Where there is danger of falling due to achange in floor levelc) In case of balustrades, stairs and floors.
CRITICAL LOCATIONSVERTICALWALLSVertical walls - with residual protection or SILL LVL > 0.75m (not likely to be subjected to human impact).
CASE-2Vertical walls ; Hs < 0.75m & Hf < 1.5m (human impact but no risk of fall)
CASE- 3Glass shelter, risk of fall
Case: 4Glass acting as a balustrade, parapet or a railing (human impact and risk of fall both)

CONCLUSIONGlass production has changed substantially over the past 4,000 years.todays float technology is characterized by continuous production and the capability of producing a wide range of glass thicknesses, sizes, and cFabricated glass products further expand the use of glass for a variety of purposes, including safety, security, sound control, and energy efficiency colors.Glass is a dynamic and important part of residential and commercial building design.It has the importance of glass in todays construction environment as a medium for natural lighting and energy conservation
