HEWEX® PEM Light

Economical Structural Electromagnetic Shielding System

Not every project requires the highest achievable level of electromagnetic shielding. For many facilities, the primary engineering objectives are long-term durability, efficient integration with the building structure and cost-effective implementation without compromising operational reliability.

HEWEX® PEM LIGHT has been developed precisely for these applications.
As the foundation level of the HEWEX® technology family, it enables engineers to incorporate Structural Electromagnetic Shielding directly into the building envelope while providing a balanced combination of shielding performance, structural durability and economic efficiency.

Rather than functioning as an additional surface treatment, HEWEX® PEM LIGHT integrates electromagnetic protection into the structure itself, creating a permanent engineering solution designed around the specific requirements of each project.

When Is HEWEX® PEM LIGHT the Right Engineering Choice?

HEWEX® PEM LIGHT is intended for projects requiring reliable electromagnetic protection while maintaining practical construction costs and limited wall build-up.

Why Choose HEWEX® PEM LIGHT?

Many conventional shielding systems rely on conductive foils, metallic meshes or surface-mounted shielding layers. While these technologies remain appropriate for numerous applications, HEWEX® PEM LIGHT follows a different engineering philosophy. The shielding function is permanently integrated into the structural building element, allowing the protection system to become part of the wall, floor or ceiling rather than an exposed layer requiring additional protection during construction or operation.

Key Engineering Advantages

  • Structural Electromagnetic Shielding integrated into the building envelope
  • Economical engineering solution for new and refurbished facilities
  • Limited wall build-up
  • High mechanical durability
  • Corrosion resistance through encapsulated Conductive Layers within the Mineral Matrix
  • Permanent integration with the building structure
  • Stable shielding performance throughout the operational life of the facility
  • Project-specific engineering tailored to operational requirements

Typical Shielding Performance

HEWEX® PEM LIGHT enables the engineering of shielding systems achieving approximately:Frequency Typical Shielding Effectiveness 300 MHz 60–65 dB 1 GHz 82–88 dB 10–18 GHz 90–100 dB
As frequency increases, the shielding performance continues to improve, making HEWEX® PEM LIGHT suitable for numerous applications requiring reliable protection against electromagnetic interference and high-frequency radio emissions.
Actual Shielding Effectiveness depends on project-specific engineering assumptions, structural configuration and execution quality.

Typical Applications

HEWEX® PEM LIGHT is commonly specified for:

Server rooms

Data centres

Research laboratories

Telecommunications facilities

Technical equipment rooms

Monitoring and security centres

Selected public administration facilities

Refurbishment projects requiring improved electromagnetic protection

Why Choose HEWEX® PEM LIGHT Instead of Conventional Shielding Solutions?

Conventional shielding systems based on conductive foils, metallic meshes or lightweight metallic enclosures are capable of providing comparable levels of Shielding Effectiveness in many applications.
These technologies continue to represent the correct engineering choice for numerous projects.

HEWEX® PEM LIGHT was developed for projects where performance is measured by more than attenuation values alone.
Its engineering advantages extend beyond Shielding Effectiveness to include:

  • permanent structural integration,
  • superior mechanical durability,
  • corrosion resistance,
  • long-term stability of shielding performance,
  • reduced vulnerability during installation and refurbishment,
  • and simplified lifecycle maintenance.

Instead of attaching electromagnetic protection to the building, HEWEX® PEM LIGHT makes electromagnetic protection part of the building itself.

This engineering philosophy provides a durable solution capable of maintaining its protective characteristics throughout the operational life of the facility.
