What is toughened glass?

• Definition
• The toughened glass is a single-layer glass in
  which a tension-spread system forms due to
  conscious heat treatment. Because of this, the
  mechanical resistance ability of the glass rises
  seven eight times.

Technical description

• In both surfaces of the glass sheet there is
  compression stress, which decreases along the
  thickness of the glass sheet and in the centre it
  forms tension stress. The compression and tension
  stressed fields are separated from each other
  with neutral zones.
• If the toughened glass is tried to be bent, first
  the compression stress decreases on the pulled
  surface and just after the tension stress will
  form, which leads to breakage.
• As a result of this, the toughened glass has
  bigger mechanical strength and hardness than a
  traditional float glass.

Fields of application

• Glass canopies
• Glass roofs
• Glass stairs
• Glass floors
• Glass walls, doors without frames
• Shower stalls
• Glass strengthening ribs for glass walls
• Load-bearing glass implements, load-bearing glass
  beams, glass coverings
• Point-jointed facades
• Glass solutions in interior decoration
  (pl.shelves, tables, displays)

Glass walls without frames

• The toughened glass sheets, doors without frames
  are produced for mainly indoor utilization,
  because the meeting edges are grinded and there
  is a 2-7 mm-wide gap between them.
• The doors can be
• opening, swinging
• sliding
• folding
• Many manufacturers produce fittings for
  assembling of toughened glass sheets, such as
  SEVAX, DORMA, CASMA, GEZE, etc.
• For installation of glass walls and doors without
  frames we use catchers chosen by the customers.
