Insulation Felts
Insulation felts, often known as NVH products (Noise, Vibration, and Harshness parts) are used for
acoustic and thermal insulation in the automobiles. These are Bonnet liner, Outer dash, Wheelhouse,
and Outer floor under shield. These parts not only provide noise protection inside the car but also a
reduction in the noise emission outside. Uses of NVH parts in automobiles started after introduction
of EURO norms in the sector.
Product characteristics
The NVH products or insulation felts are 100% polyester non-woven technical textile products. These
products are classified based on the manufacturing process as needle-punched, phenolic resin bonded
and thermoplastic. The felts are generally soft and used with or without harder backing. The thermal
insulation products provide dissipation of heat at high temperature areas in the engine and under car
body. The NVH products combine noise and heat protection function into the integrated comfort
system.
Key growth drivers of Insulation felts industry
The primary growth driver for the insulation felts is the sales of passenger cars, MUVs and SUVs
(explained in the beginning of the Mobiltech segment). The insulation felt industry is expected grow
in line with the automotive market.
Consumption norms, market size and future forecast
The insulation felt is a 100% polyester non-woven technical textile product. The usage varies based
on the location and technical requirement. The usage varies typically from 12 kilograms in small cars
to 15 kilograms in large vehicles.
