Transportation Thermal Insulation

Auto Insulation

This automotive thermal insulation coating is ideal for heavy-duty vehicles including:

  • Buses
  • Sprinters
  • RV Trailer Homes
  • Motor Homes
  • Emergency Response Vehicles
  • Public Service Vehicles
  • Rail Cars
  • Tractor Trailers


Unlike other automotive thermal insulation products on the market today, Mascoat Transportation-DTA is a one-part system. DTA is a lightweight coating that adheres to any ferrous substrate in the transportation industry without the need for a primer. It keeps temperatures in cabs and cargo areas more comfortable and stable at minimum thickness (0.5–2.0 mm).


 Other benefits of Mascoat Transportation-DTA include:

  • Non-combustible
  • Seamless membrane for substrate protection
  • Easily applied to irregular surfaces
  • Fast clean up with soap and water
  • Low VOC content


Though Mascoat Transportation-DTA only adds 0.046 lbs/ft2 per coat, as a beneficial secondary benefit, its’ direct bond to the substrate allows it to lessen surface borne noise. If sound is your primary concern, please see our Mascoat Sound Control-dB product.


Application is recommended on surfaces needing a thermal barrier including:

  • Engine compartments
  • Roofs
  • Floors
  • Side walls
  • Interiors
  • Exterior roofs
  • Underbody
