When you’re ready to upgrade your van for comfort, noise reduction, and a more professional finish, ceiling liners are a game-changer. Today, we’re diving into the unboxing of Legend DuraTherm Ceiling Liners for RAM ProMaster City—one of the top-selling thermal barrier products we offer here at Upfit Supply.

This blog will walk you through the contents of the kit, the benefits of this ceiling liner system, and a few helpful tips to ensure a seamless installation. Whether you’re building out a work-ready van or simply want to control heat and sound, this product is worth your attention.

What Comes in the Box?

Unboxing the Legend DuraTherm Ceiling Liners for RAM ProMaster City reveals two main components:

  • The DuraTherm insulated ceiling panel
  • An optional set of aluminum ceiling sills for a finished look

The ceiling liner ships folded due to its size. Despite that, it’s lightweight and easy to manage. We also found a hardware kit and a reference sheet with basic part numbers inside. However, the complete installation manual must be downloaded from our website.

Overview of the DuraTherm Ceiling Panel

The DuraTherm ceiling liner is built with functionality and performance in mind. Here’s what stood out immediately:

  • Insulated backing with foil and dense black foam for thermal and acoustic control
  • Pre-scored rear side to assist with fitment over OEM trim contours
  • Pre-drilled mounting holes that align with factory ceiling points
  • Custom contouring that fits the RAM ProMaster City perfectly
  • Grey textured finish for a clean, OEM-style look

One side features a foil-backed insulation layer, which adds a barrier against radiant heat and absorbs sound. This can make a significant difference when you’re working in extreme summer or winter conditions.

Benefits of DuraTherm Liners for the RAM ProMaster City

Let’s take a moment to talk about why this ceiling liner system is one of the best upgrades you can make.

1. Thermal Control

Thanks to the insulated backing, this panel helps stabilize interior temperature. Whether it’s a blazing summer day or a frigid morning, your van stays more comfortable.

2. Sound Dampening

Noisy cargo areas are a thing of the past. The layered construction reduces vibrations and road noise, making it easier to work, talk, or listen to music inside your van.

3. Custom Fit

This isn’t a one-size-fits-all solution. The liner is pre-cut to follow the curves and angles of the ProMaster City ceiling, ensuring a snug, factory-like fit without major modification.

4. Easy Installation

With pre-drilled holes and a mix of plastic push clips and self-threading screws, installation is simple and clean—no measuring or guesswork needed.

Optional Upgrade: Aluminum Ceiling Sills

We also unboxed the Legend aluminum ceiling sills, which are a premium add-on we highly recommend. These close the gap between the ceiling and sidewall liners, giving your van a finished, professional appearance.

Each sill includes:

  • Diamond tread aluminum plates (4 pieces total)
  • Pre-drilled mounting holes
  • Hardware and connector plates to join sections seamlessly

While technically optional, we believe the ceiling sill kit adds polish and continuity to the full interior upfit. Without it, you may notice visible seams or gaps where wall and ceiling liners meet.

Installation Notes and Tips

What You’ll Need:

  • Basic hand tools
  • Gloves (sharp aluminum edges)
  • The installation PDF, which you can find on our product page

Step-by-Step Summary:

  1. Download installation instructions from our site before you begin.
  2. Remove any OEM ceiling components or trim that may obstruct the liner.
  3. Position the liner inside the van using the pre-scored guide lines for alignment.
  4. Secure the liner using push-in rivets or self-threading screws, depending on your kit.
  5. Install aluminum ceiling sills by lining up the plates and attaching them with included screws and connector brackets.

Take your time, especially when handling the aluminum parts. Though the process is straightforward, it’s always best to work slowly to ensure accuracy and safety.

  • Contractors working in extreme climates
  • Delivery professionals wanting a quieter ride
