Machine safety windows in comparison
SICURTEC_SHIELD - Multi-layer polycarbonate-acrylic-glass composite for special applications SICURTEC_SHIELD

Excellent protection with
equally low weight

SICURTEC_SHIELD consists of a multi-layer polycarbonate-acrylic-glass composite and offers maximum protection for a wide range of special applications.

When looking for an absolute all-round safety glass, there is no way around SICURTEC_SHIELD. It is particularly suitable for plant housings and machine housings, security vehicles as well as construction, agricultural and forestry machines. Even when subjected to extreme violence, it convinces with its enormously high resistance. Furthermore, it offers a weight advantage of 50% compared to the glass equivalent. Thanks to its high scratch resistance, it guarantees a clear view and a long service life, even under the toughest conditions. Due to the innovative no-spall design, spalling in the event of a potential impact is a thing of the past.

Standards and recommendations

Important standards

A machine safety window far beyond the norm

SICURTEC® machine safety windows were developed to push the limits of puncture resistance further up. The relevant standards only serve SICURTEC® as a guide. In fact, the relevant characteristics of SICURTEC® products are in some cases far above the level set by standards.

  • EN ISO 23125 (EN 12415 lathes)
  • EN 16090-1 (machining centres)
  • EN 13218 (grinding centres)
  • The standard for lathes EN ISO 23125 ends at 8,000 joules, SICURTEC® builds elements that have been tested up to over 16,000 joules.

Replacement info

The fact is: Machine safety windows can lose their retention capacity. They become brittle. The unprotected contact with cooling lubricants and unsuitable cleaning agents speeds up the process many times over. It is therefore necessary to protect the polycarbonate. The graphic below clearly shows how this protection affects the longevity.

Window replacement every 5 years

Laminated polycarbonate safety glass, gluing in a stainless steel frame or edge protection with aluminum tape or NBR rubber profiles protect polycarbonate against rapid aging. Nevertheless, the German BIA as well as the VDW and IWF recommend to replace machine safety windows after 5 years. Pure polycarbonate windows at least every 2 years!

When to replace windows immediately:

  • Deformation (bulging) of the polycarbonate due to an impact 
  • Leaky edge seal
  • Coolant is between the various components
  • Destruction or damage to one of the window sides
Ageing of polycarbonate
  • Particular resistant, even when subjected to extreme violence
  • 50% weight advantage over glass equivalent
  • High scratch resistance
  • Very good transparency
  • No spalling in the event of an impact
Frame systems and seals

Frame systems for perfect sealing of the machine safety window

Chemical influences, such as contact with cooling lubricants, can cause considerable damage to machine safety windows. Unless, for example, the window with glass is glued into a stainless steel frame. As a all-round provider, we provide you with three standard frame profiles with L, Z and S profiles. Due to the product flexibility, all three profile types can be adapted to any pane thickness according to the desired retention effect. Same applies to frames, which are developed by us especially to customer requirements and which are produced as already glued and finished elements.
