GEWE®-tvg is manufactured by heating and cooling the glass in a controlled way. The mechanical strength and thermal shock resistance of the semi-tempered glass GEWE®-tvg lies between the values for float glass and toughened safety glass. The semi-tempered glass can thus be used where the bending strength and temperature of float glass is insufficient but toughened safety glass does not provide the required level of protection because of its fragmentation into fine shards when shattered, for example in overhead glazing applications.
