Building Safety – CER Directive
Protect the energy infrastructure, quickly, securely and cost-effectively
New safety requirements call for smarter solutions
The EU’s new CER Directive (Critical Entities Resilience Directive) and Danish regulations impose stricter requirements on how energy companies protect their buildings against explosions, heat and intrusion.
At Optinor, we help you meet these requirements, whilst creating a safer workplace without major investment or lengthy operational downtime.
Practical solutions for real-world challenges
Securing infrastructure doesn’t have to be complicated.
Optinor offers safety film and specialist glass that reinforce existing windows and façades.
Our solutions reduce the risk of injury from explosions, flying glass, fire and vandalism, without altering the building’s appearance.
Installation is carried out quickly and professionally by our certified fitters, whilst the business continues its normal operations.
This makes our solutions ideal for power stations, district heating plants, gas storage facilities, control centres and technical buildings.

What is the new CER legislation, and why is it important?
The new Critical Entities Resilience (CER) legislation is designed to ensure that organisations providing critical services, such as energy, can withstand serious incidents such as explosions, sabotage or extreme weather.
The aim is to protect people, society and the security of supply.
What are the requirements for physical security?
You must be able to demonstrate that your buildings and installations have:
Preventative measures against explosions and intrusion
Safe escape routes and access arrangements
Materials capable of withstanding heat and pressure waves
Contingency plans and rapid recovery plans
Have the solutions been approved and tested?
Yes. We use CE-approved products, tested in accordance with international standards for blasting and safety protection.
We always document the results so that you can use them in your company’s safety reports.
How do you secure windows?
There are several solutions available, depending on the level of security you require. At Optinor, we offer:
Window film (security film): A flexible and cost-effective solution that can be fitted directly onto existing windows and increases resistance to break-ins.
Security glass (Hammerglass): A special polycarbonate-based glass material that is extremely resistant to impact and vandalism. A robust solution when extra security is required.
Security windows: The most advanced solution, where the entire window is designed to withstand heavy loads and ensure maximum security.
We always listen to your needs and help you find the solution that best suits your project and your security requirements.
Can Hammerglass be fitted to existing window frames?
Yes, this is often possible – a flexible solution compared with replacing the whole window.
Do the rules apply to my business?
If you run a business in the field of electricity generation, distribution, district heating, gas or large-scale energy plants, these rules may apply to you.
The final assessment is carried out by the Danish Energy Agency, but all businesses in the supply chain are encouraged to review their physical security.
How can Optinor help?
Optinor offers safety films and glazing solutions that can be fitted directly to existing windows and façades.
They enhance resistance to pressure waves and flying debris without the need for major alterations – a quick, professional and cost-effective solution.
How long does the installation take?
Our fitters can usually install security film in a matter of days – depending on the size of the building.
It does not require any downtime, and the work can be carried out whilst the facility is operating as normal.
What is safety glass/shatterproof glass?
Shatterproof glass, also known as safety glass, is made from polycarbonate, which is 300 times stronger than glass. It can withstand vandalism, break-ins, gunshots or explosions.
What is the difference between burglar-proof windows and security film?
Burglar-proof windows are typically made from thicker, reinforced glass and often feature multiple locking mechanisms. Security film is a more flexible and cost-effective solution that can be fitted to windows to improve security. Burglar-proof windows may require a complete replacement of existing windows, whilst security film can be easily installed.
