HEAT SHIELDS: Heat shields are multi layered products mostly covered with aluminum, designed to protect structures from extreme temperatures by reflecting heat or preventing its transfer while providing noise reduction. A good heat shield needs to have high thermal resistance and thermal emittance, so it can withstand high temperatures and reflect and release the heat away from itself. Heat shields with their multilayer sandwich designs have also noise reduction abilities and can be cut or thermoformed in 2D&3D designs. Most common usage are in automotive (underhood, behind dashboard, etc.), heavy duty vehicles, railway rollingstocks.
