Railway Technology


Rail is the most environmentally friendly mode of transportation. But increased comfort requirements, such as air conditioning, comfortable seats and tables, easily accessible lavatories and CET tanks have made trains heavier and more expensive to operate. To maintain its environmental advantage, energy efficiency has to be improved – without compromising passenger safety and comfort.

Improving energy efficiency is a key challenge for today’s railway industry. Armacell’s flexible equipment insulation and sustainable foam cores for lightweight constructions can help to increase energy efficiency and passenger safety and comfort. Our solutions are used in rail vehicles all over the world, where they ensure safe and smooth operation.

To achieve the highest possible level of safety in trains, both materials and components must meet strict fire, smoke and toxicity requirements. EN 45545 is a seven-part European standard for fire protection on railway vehicles. The objectives of this standard are to minimize both the risk of a fire starting and spreading within railway vehicles and its effects on passengers and employees. As a consequence, this provides the best level of protection against the occurrence of a fire on board. Our ARMAFLEX RAIL SD helps meet this standard with its extremely low smoke density and superior fire resistant behavior.


ArmaFlex Rail

In rolling stock, heating, ventilation and air-conditioning (HVAC) equipment is the second largest energy consumer after the traction. Insulating this mechanical equipment with our closed-cell and highly flexible ArmaFlex Rail products is one of the simplest and most efficient measures to save energy in railway vehicles. We are also proud to be the first flexible closed-cell insulation to meet hazard levels 2 and 3 for railway vehicles according to EN 45545

ArmaForm Cores

Lightweight constructions offer enormous potential for weight savings in a wide range of rail applications. Innovative composite solutions which are based on our recyclable ArmaForm core materials can significantly reduce the weight – from the driver´s cab, body shell and floor to doors, lavatory modules, compartment walls and tables.
