HEWEX^® PEM Premium

Advanced Structural Electromagnetic Shielding System

Many modern facilities require a level of electromagnetic protection that exceeds the capabilities of conventional shielding systems. In environments where infrastructure reliability, secure data transmission and resilience against electromagnetic interference are essential, shielding becomes a critical component of the overall engineering strategy.

HEWEX^® PEM PREMIUM has been developed as an advanced Structural Electromagnetic Shielding system engineered to deliver exceptionally high shielding performance while maintaining long-term durability, superior EMC integrity and seamless integration with the building structure.
Rather than functioning as an isolated shielding layer, HEWEX^® PEM PREMIUM becomes an inherent part of the facility, providing reliable protection throughout its operational lifecycle.

HEWEX^® PEM PREMIUM is designed for facilities requiring highly effective electromagnetic shielding, even at lower frequencies, and a very high level of protection in the high-frequency range. The technology is applicable wherever shielding is a component of the facility’s security system, not just the protection of a single room.

Compared to the basic level of protection, HEWEX ^® PEM PREMIUM technology has been designed to achieve significantly higher shielding effectiveness over a wide frequency range and to improve the electromagnetic tightness of the entire system.

A characteristic feature of the technology is the use of controlled absorption of electromagnetic energy , which supports the shielding process and limits the unfavorable phenomena associated with wave reflection from classic metal screens.

This approach allows us to design protection systems adapted to the modern requirements of critical infrastructure, laboratories and facilities with increased security requirements.

How effective can you design?

HEWEX^® PEM PREMIUM enables the design of systems achieving approximately 70–80 dB of shielding effectiveness at 30 MHz, approximately 80–90 dB at 100 MHz and over 105 dB from approximately 300 MHz.

This level of shielding performance across a broad frequency range makes HEWEX® PEM PREMIUM suitable for facilities requiring reliable electromagnetic protection and high EMC integrity.

Where do we use it?

HEWEX^® PEM PREMIUM is designed, among others, for:

EMC Laboratories

Data processing centers

Critical infrastructure

Telecommunications facilities

Surveillance and monitoring centers

Rooms requiring high confidentiality of information

State administration and security facilities

Specialized research laboratories

Why HEWEX^® PEM PREMIUM instead of classic solutions with similar effectiveness?

In many cases, a similar level of shielding effectiveness can also be achieved using traditional foils, conductive meshes, or lightweight metal shields. These solutions remain the right choice for certain applications and are still widely used.

HEWEX^® PEM PREMIUM was developed for investors who expect more than just a specific level of attenuation. In addition to shielding effectiveness, it offers permanent integration with the building’s structure, high mechanical strength, corrosion resistance, and long-term stability of protective parameters.

This makes the security system an integral part of the building, rather than an additional layer requiring special protection during operation or modernization.
