Protection starts with engineering.

Siper Glass evaluates ballistic and technical glass solutions project by project, for defence and high-security applications first, and for aviation, rail and marine projects.

Our approach

Engineering, confidentiality and a written process

Requests are received through recorded written channels; technical requirements are clarified and every project is evaluated on its own terms.

  • Technical precision

    Layer build, geometry, weight and optical requirements are considered together.

  • Project-based solutions

    Solutions defined by the application’s requirements rather than a fixed catalogue.

  • Standards-based language

    Requirements are defined with references such as EN, STANAG, UL and NIJ; conformity is documented within each project.

  • Confidentiality

    Project information and references are protected under confidentiality obligations.

Ballistic glass solutions for armoured platforms

Flat or curved, heated and polycarbonate-backed ballistic glass needs for armoured, tactical and personnel-carrier projects are evaluated per project.

Glass Technology

Engineered layer by layer

Ballistic glass is not one material but a system in which every layer has its own task.

Layer count, thicknesses and materials are defined by evaluating the target standard class, weight limit, geometry and optical requirements together.

Key Processes

The key manufacturing steps, from cutting to optical inspection

The general manufacturing steps of laminated ballistic glass. Which processes and which site a project uses is stated in writing after evaluation.

  1. 01

    Cutting and processing

    Size · edge · drilling

    The step in which glass is cut to size and template, edges are processed and holes or custom cut-outs are added where required.

  2. 02

    Bending

    Curved form

    The step in which plies for curved vehicle, yacht and architectural glazing are heat-formed to the same geometry.

  3. 03

    Lamination

    Glass · interlayer · polycarbonate

    The step in which glass, polymer interlayers and, where required, polycarbonate are assembled in a clean environment.

  4. 04

    Autoclave

    Heat and pressure

    The step in which the laminated pack is processed under heat and pressure, removing air and permanently bonding the layers.

  5. 05

    Dimensional and optical inspection

    Dimension · form · optics

    The step in which finished glass is checked for dimensions, fit and optical distortion against project requirements.

Design Criteria

Balancing weight, optics and resistance

Designing ballistic glass means balancing the protection requirement, weight, optical quality and climate conditions.

Explore the technology

  • Project engineering

    Threat-based configuration

    Glass, interlayer and polycarbonate combinations are assessed per project for the required protection level or threat class.

  • Polycarbonate layer

    Weight optimisation

    A polycarbonate layer is one of the options considered when balancing protection and weight on vehicle platforms.

  • Micro-wire

    Heated glass technology

    Concealed micro-wire heating between the layers aims to keep ballistic and marine glazing clear of fog and ice.

  • High transparency

    Optical performance

    Transparency and optical distortion targets in thick multi-layer builds are defined per project through material selection and inspection criteria.

Standards

The standard families most often referenced for ballistic glazing, and what they cover.

  • What does a standard reference mean?

    1. General informationThe scope of the standard is explained.
    2. Design referenceThe build is designed to the standard’s classes.
    3. Test reportA specific build has been tested by a laboratory.
    4. CertificateA recognised body’s certificate, with scope and validity.

Other Sectors

From marine to high-security buildings

The same engineering discipline is applied per project to vessels, high-security buildings and special applications.

Marine Glazing
