High-quality safety glass by Sprinz

High-quality safety glass for interior and exterior

Modern architecture increasingly designs generous glass surfaces. At the same time, requirements in the private and public sector as well as in commercial rooms and buildings are increasing. Glass should offer design variety, high-quality processing and a high degree of safety. Sprinz has developed various types of safety glass which are tested and certified for all kinds of circumstances.


Spridur ESG

Our SPRIDUR toughened safety glass has three characteristic properties:

Increased resistance to changes in temperature
Bending strength about 3 times greater and impact and shock resistance higher than with float glass
SPRIDUR ESG shatters into small, loose dull-edged fragments if broken, thus posing a reduced risk of injury

SPRIDUR ESG owes its special properties to a tempering process. Float glass is heated to about 620 °C in a tempering furnace while constantly kept in motion and then “quenched” with cold air. During the cooling process, the surfaces cool out faster than the core zone, which causes areas of varying stresses to form within the glass. These stress differences are what gives SPRIDUR ESG its unique properties.

The requirements for SPRIDUR ESG are defined in DIN EN 12150.

Sample applications:

Interior doors
All-glass systems
Insulated glazing
Noise protection walls
Shower enclosures


Spridur ESG-H

Spridur ESG-H

SPRIDUR ESG-H by Sprinz is a special toughened safety glass (ESG), which is subjected to the so-called “heat soak test” and thus satisfies special safety regulations.

With classic ESG there are rare occurrences of “spontaneous breaks”, caused by inclusions of nickel sulphide in the glass mixture. Nickel sulphide can increase its volume when exposed to heat and thereby destroy the glass. However, these nickel sulphide inclusions cannot be detected by means of optical testing methods.

The heat soak test helps to prevent these “spontaneous breaks”. The prestressed glass is heated to 280 °C and kept at that temperature for at least 4 hours in a heat soak furnace.

The test for ESG is currently required by law for the DIN 18516 Standard Part 4 (ventilated façades).

Sample applications:

Façade glazing
All-glass systems (on request)
Shower enclosures (on request)
Interior doors (on request)


Spridur TVG

Spridur TVG

The partly prestressed safety glass SPRIDUR TVG is subjected to a thermal hardening process just like SPRIDUR ESG, but with a slower cooling process. It too is more resistant to thermal and mechanical stresses than float glass.

SPRIDUR TVG is mainly used as a laminated safety glass.

Sample applications:

Point-supported overhead glazing
Glass balustrades
Glazing that has to stand up to thermal stresses as well as construction regulations
Applications that require higher bending strength than float glass but a different breakage behaviour than SPRIDUR ESG.
Glazing which needs to achieve higher break resistance and residual load capacity in the SPRISAFE VSG version.


Spriform ESG

To produce SPRIFORM ESG, a float glass pane is heated to the softening point and then shaped in a freeform process. After the bending process, the glass is cooled quickly, which gives it the mechanical properties of prestressed glass.

The requirements for SPRIFORM ESG are defined in DIN EN 12150.

The list of possibilities for using SPRIFORM ESG is virtually limitless. Bent glazing is very popular these days. Partly for functional reasons, partly purely as a design element and often as an aesthetically sophisticated combination of both. We use state-of-the-art bending technology to produce bent toughened safety glass of the highest quality.

Sample applications:

Shower units
Design glass
Other interior and exterior applications such as shop fitting


Sprisafe VSG

Sprisafe VSGSPRINZ Sicherheitsglas SpridurVSG Durchschuss web.jpg

SPRISAFE laminated safety glass (VSG) comprises at least two glass panes and a intermediate layer consisting of tear-resistant polyvinyl-butyral film (PVB). In the autoclave, glass and film are fused into an inseparable unit under great pressure and heat.

SPRISAFE VSG by Sprinz stands out with its high degree of safety due to the tear-proof PVB layer and its adhesive effect on the glass.

If the glass breaks – due to mechanical overload – the pieces stick to the PVB film and reduce the chance of injury. SPRISAFE VSG is available in different combinations of float glass, SPRIDUR ESG and SPRIDUR TVG. Variants with colour and soundproofing films are also possible.

The requirements for SPRISAFE VSG are defined in DIN EN ISO 12543 parts 1–6.

Sample applications:

Walk-on glazing intended to prevent falling in
Safety glazing for balustrades and banisters intended to prevent falls

Special combinations for special glazing:

impact resistant as per DIN EN 356
break resistant as per DIN EN 356
bulletproof as per DIN EN 1063
with alarm loop
ball resistant
