I need new carpet for my muscle car. What is standard backing, underlay, and mass backing? Please help me to understand.

Choosing the Perfect Carpet for Your Muscle Car

Standard Backed Carpet

Standard backed carpet features a poly backing, with poly standing for polyethylene, a thin plastic material measuring 1/16". This material is bonded to the carpet as well as the jute padding beneath to provide optimum comfort. 

Standard Backed Carpet with Underlay

When you take out the carpet in your vehicle, you might find that there is underlay on top of the floor pan or at least some leftover remnants of it. It's a smart move to remove the old underlay and replace it with new underlay before installing your new standard backed carpet. Underlay is specifically designed to provide extra cushioning and breathability while also ensuring that the carpet remains protected from moisture, rot, and unpleasant odors. In addition, underlay helps to further insulate the interior, reducing heat/cold and road noise when installed with standard backed carpet.

Mass Backed Carpet

The epitome of luxury and durability lies in the form of mass backed carpet, albeit at a higher price point. Crafted through the fusion of a material known as Ethylene Vinyl Acetate (EVA), typically 45ml thick, with a vehicle's molded carpet, this option offers a thicker and heavier composition. It not only excels in reducing road noise but also provides superior insulation against heat, cold, and external elements.
