In today’s digital environment, protecting confidential information goes beyond cybersecurity systems, firewalls and encrypted networks.
Many organisations invest heavily in securing their IT infrastructure, but one area often overlooked is the physical building itself, particularly its glass windows.
Electronic equipment, wireless devices and communication systems generate electromagnetic signals. Some of these signals can travel beyond the building, potentially creating vulnerabilities for organisations handling sensitive information.
With modern Singapore offices increasingly featuring large glass facades and meeting rooms, electromagnetic shielding is becoming an important consideration in building security.
At PACCO Architectural Films, we offer Vianovix SpyLock35, a specialised transparent RF and EMI shielding window film designed to reduce electromagnetic signal transmission through glass.
SpyLock35 is an advanced electromagnetic shielding film developed by Belgian specialist Vianovix.
Unlike conventional solar control films, SpyLock35 incorporates a transparent electrically conductive coating engineered to attenuate radio-frequency (RF) electromagnetic signals.
The film helps reduce electromagnetic signals passing through treated windows while maintaining high optical transparency.
It can be installed onto existing glazing, making it a practical retrofit solution for commercial buildings and facilities that require additional electromagnetic protection without replacing their windows.
Electronic equipment such as computers, wireless communication devices and other digital systems can generate electromagnetic emissions.
Under certain conditions, these emissions may be detectable outside a protected space using specialised equipment.
Windows can be a potential weak point in a building’s electromagnetic shielding because ordinary glass provides limited attenuation of many radio-frequency signals.
SpyLock35 addresses this vulnerability by introducing a conductive shielding layer onto the glass.
Its main functions include:
Importantly, SpyLock35 is intended to complement an organisation’s existing physical and cybersecurity measures, rather than replace them.
SpyLock35 has been evaluated for electromagnetic shielding effectiveness using established RF testing methodologies.
| Technical Specification | SpyLock35 |
|---|---|
| Product Type | Transparent RF/EMI shielding film |
| Shielding Effectiveness | ≥32 dB |
| Tested Frequency Range | 10 MHz – 26 GHz |
| Visible Light Transmission | ≥75% |
| Referenced Test Standards | ASTM D4935, IEEE Std 299 |
| Installation | Existing glazing or integration into laminated glass |
| Technology | Patented conductive coating |
A shielding effectiveness of 32 dB represents a substantial reduction in radio-frequency power transmitted through the tested material.
However, actual shielding performance in a building depends on more than the window film alone. Glass frames, surrounding walls, installation details and other openings must also be considered.
Electromagnetic shielding is particularly relevant for buildings and facilities where information confidentiality, equipment reliability or controlled electromagnetic environments are important.
Government organisations and defence-related facilities may require additional protection against electromagnetic information leakage.
SpyLock35 can form part of a broader architectural shielding strategy for offices, secure meeting rooms and other sensitive areas.
Organisations handling confidential business strategies, financial transactions, intellectual property and sensitive discussions may benefit from additional RF shielding.
SpyLock35 provides a discreet solution that preserves the modern appearance of glass-fronted offices.
Banks, financial institutions, technology companies and organisations processing sensitive information may consider RF shielding as part of their overall security planning.
Research and development facilities often contain specialised electronic equipment and valuable intellectual property.
RF shielding films may help reduce electromagnetic transmission through windows, supporting broader EMI management and information security requirements.
In spaces where highly confidential information is discussed or processed, SpyLock35 can be considered alongside other shielding measures, such as protected walls, doors and cable penetrations.
This is an important consideration when planning electromagnetic shielding for any building.
While SpyLock35 provides tested RF shielding performance at the material level, installing window film alone does not automatically create a fully shielded room.
Electromagnetic signals may also pass through surrounding walls, window frames, gaps, doors, ventilation openings and other unshielded areas.
For projects requiring specific shielding performance, the entire room or building envelope should be assessed.
Proper installation details, including conductive connections around glazing edges where required, can also influence overall performance.
For more demanding applications, RF measurements before and after installation can help evaluate the effectiveness of the completed shielding system.
At PACCO, we believe that understanding the client’s security objectives and building conditions is essential before recommending an appropriate film solution.
Because SpyLock35 is designed to attenuate RF signals, wireless communication passing through the treated glass may also be reduced.
However, installing SpyLock35 does not necessarily eliminate mobile reception or Wi-Fi connectivity within a building.
Actual effects depend on factors such as signal sources, building construction, coverage and the extent of the shielding installation.
Wireless network requirements should therefore be considered during the planning stage.
Established in 1988, PACCO specialises in architectural films and innovative glass solutions for residential, commercial and institutional applications.
Beyond conventional solar control and safety films, we continue to introduce specialised technologies that address evolving building requirements.
With SpyLock35, we offer an additional solution for organisations seeking greater control over electromagnetic transmission through glazing.
Our approach includes:
We believe window films should do more than improve the appearance of glass. They should provide practical solutions to real building challenges.
As buildings become increasingly connected and organisations place greater importance on information security, electromagnetic shielding deserves consideration during building design and upgrading works.
SpyLock35 offers a transparent, retrofit-friendly approach to reducing RF transmission through glass without sacrificing natural daylight.
Whether you are planning a secure government facility, corporate office, research laboratory or specialised meeting room, PACCO can assist in reviewing your glazing requirements and exploring suitable shielding solutions.
