Municipal emergency vehicles
Sound insulation and acoustic solutions
To reduce airborne and structure-borne noise, heavy-duty films (Terodem® and Teroform®) made from bitumen or EVA are used, which provide significant noise reduction, particularly on metal surfaces such as wheel arches, bulkheads or engine covers. Combined with recycled PUR foams or melamine resin-based acoustic foams such as Basotect® G+, this creates an effective insulation package that absorbs both low and high frequencies. These materials are suitable for installation in cabin trim, doors, floor structures or technical areas.
Polyester fibre fleeces (Fiberform 62T SL or Silphon®Fiber) are also increasingly being used – they are dimensionally stable, moisture-resistant, recyclable and can be processed flexibly. In the interior, they contribute to acoustic comfort and thermal insulation.
A balanced temperature profile is crucial, particularly in vehicle cabins – both in summer and winter.
In these zones, closed-cell PE foams (Plastazote MP15FR) or synthetic rubbers such as Armaflex®, Vibra®Flex or K-Flex are integrated, providing reliable thermal insulation while remaining moisture-repellent. Aluminium-laminated insulation mats are primarily installed in ceiling and roof areas to reflect radiant heat.
Vibration Control – Effectively Isolating Vibrations
A frequently underestimated source of disturbance in municipal vehicles is persistent vibration transmitted into the cab from engines, attachments or the chassis. High-quality elastomer materials such as Sylomer®, Sylodyn® or rubber-metal elements are used for effective decoupling. These materials act as vibration isolators and are installed at specific points beneath machinery, equipment or load-bearing structures.
