Freightliner FLC120 Floor Covers & Mats

Freightliner FLC120 Flooring Accessories That Cut Noise, Block Heat, and Keep Mats in Place

If your FLC120 cab feels loud, hot, or tinny, start under your feet. This page focuses on semi truck flooring accessories that improve comfort and stability, without replacing the actual mats. Add the right underlayment and hardware and you'll notice a cleaner install, less vibration, and a more solid feel in the cab. These upgrades also pair well with a future semi truck floor replacement or semi truck interior restoration. You handle the foundation first. Then you drop in new flooring later when It's available.

Quiet the Cab With Sound Deadening Floor Insulation

Road noise and vibration travel through the floor pan and firewall. Install sound deadening truck floor insulation to reduce rattles and resonance. A truck cab hush mat layer helps stop metal vibration, which cuts the buzz you hear at highway speed. For extra comfort, add a foam-style insulation layer on top of the sound deadener. It helps absorb higher-pitched tire noise and adds a slight cushion underfoot.

Block Radiant Heat and Help Control Moisture

If the floor gets hot near the firewall, use a thermal insulation floor kit style barrier under your flooring. This type of insulation reflects radiant heat back toward the source. It can also help with moisture control when you seal seams properly. Use insulation foil tape to close gaps between sheets. That seal keeps heat from leaking through cracks and helps prevent edges from peeling over time.

Stop Floor Mats From Sliding With Securement Hardware

Even the best semi truck floor mats won't feel right if they slide forward. Add a truck floor mat securement kit to anchor mats firmly to the floor. You reduce shifting and bunching. You keep the pedal area clearer. You also get a cleaner look because the mat edges stay aligned.
