Having recently celebrated its 85th birthday, the Moscow metro has undergone many changes during its lifetime.

From expanding to 15 lines with 275 stations to establishing the Moscow Central Ring and the Moscow Central Diameter, the metro continues to evolve and grow in importance as a means of transport. But one thing remains unchanged, and that’s the priority of the safety of passengers and employees.

The challenge

Every day, the huge metropolis of Moscow’s is served by a hard-working metro system that transports up to 10 million people. Considered to be one of the most beautiful metros in world, it’s a well-developed underground system that allows the city dwellers save valuable travel time. But like all metros, it’s considered to be a high-risk zone. The very nature of a metro
means that many people are accumulated together in a confined space, deep beneath the streets. In the case of danger, it’s very difficult to evacuate people quickly. A potential fire – and the related smoke – in such a setting is deadly. That’s why designers need to pay extra attention to safety issues when considering construction within the metro system. With the safety of employees and passengers at heart, the Moscow metro has included non-combustible thermal insulation made from ROCKWOOL’s natural stone wool as a key element within its renovations and new builds.

The Moscow metro


The solution

On May 15, 2020, the Moscow Metro celebrated its 85th anniversary. Transporting approximately 2.5 billion passengers per year, and with the double-track lines covering circa 440 km, primarily underground, the number of stations to allow commuters to access the metro is steadily growing. In addition to this new construction, there is constant renovation taking place throughout the metro to increase the level of comfort and safety with the help of modern and high-quality materials and technical solutions.

Metro stations at Rasskazovka, Olkhovaya, Michurinsky Prospekt, Nekrasovka and the transport hubs at Kosino - Ukhtomskaya and Likhobory are just some of the projects that implemented ROCKWOOL’s non-combustible products. To secure protection against the weather – and to add extra fire safety – VENTI BATTS slabs were used for their façades. And at the Nekrasovka station, ventilation systems using ALU1 WIRED MAT were installed to ensure extra resistance to fire.

It wasn’t only the station façades that got a makeover, the roofs were also refurbished. Filatov lug and Prokshino stations opted for ROCKROOF – a complete insulation system where installation is made simple, as every element needed is included, has been checked and tested for safety and works perfectly in conjunction with other components. ROCKROOF’s thermal properties ensure that commuters experience a pleasant indoor environment when passing through these stations, and as a fire-resistant insulation, secure a safe journey for everyone.

Fire safe insulation from ROCKWOOL

Our insulation is classified as A1 according to the Euroclass system. These are the top fire performance classifications, and are based on several characteristics including:

  • Ignitability
  • Flame spread
  • Heat release
  • Smoke production
  • Propensity for producing flaming droplets/particles

What’s more, ROCKWOOL insulation also offers additional benefits, including:

  • Thermal properties
  • Acoustic performance
  • Robustness
  • Aesthetics
  • Water repellence
  • Circularity

Why products from ROCKWOOL?

Being involved in such a long-term – and prestigious –
project is a testimony to both the effectiveness of
ROCKWOOL’s products and the hard work of the
Russian team. “We’re lucky here at ROCKWOOL Russia
that our partners are very loyal to our company brand.
They know how good our products are and believe in
our quality,” explains ROCKWOOL Russia’s Managing
Director, Marina Potoker.
By the end of 2022, a further 57 new stations will
have opened within the Moscow metro, extending
the length of the underground network by 450 km.
For 90 percent of the capital’s residents, the metro
will be within walking distance from their homes. And
innovative products from ROCKWOOL mean that the
transport won’t only be more accessible, but also safer
than ever.

Fire safe insulation from ROCKWOOL

Installing fire safe insulation is a great way to ensure the safety of building occupants – and to prevent the spread of fire to limit structural damage. Made from non-combustible stone wool, ROCKWOOL’s insulation slows down the spread of fire, containing it within one compartment of a building for as long as possible, while creating a safer environment for firefighters to combat the flames. ROCKWOOL insulation is made from non-combustible, fire-resistant stone wool that can withstand temperatures above 1,000°C. With minimal organic content, no significant toxic smoke is produced either.

"Because we do not build or renovate as we used to do 50 years ago, being aware of the possible consequences of this change, like increased fire risks for example, is critical. Non-combustible materials have an important role to play in keeping modern buildings and their occupants safe.”
