Installing DuraTherm Ceiling Liners in RAM ProMaster City

Last updated September 26, 2025

Looking to cut down on noise, improve insulation, and give your van a clean, finished look? Installing DuraTherm Ceiling Liners for the RAM ProMaster City checks all the boxes. In this guide, we’ll walk you through the simple installation process using just basic tools. With a quick install and long-term benefits, this upgrade is an easy way to boost both comfort and durability in your van.

Why Installing DuraTherm Ceiling Liners in RAM ProMaster City Matters

We face extreme temperatures on job sites. Therefore, insulating your ceiling helps regulate interior heat. Additionally, these liners add sound-dampening foam backing, reducing road noise. Finally, the grey vinyl finish delivers a clean, professional look that clients notice.

Key Features of DuraTherm Ceiling Liners

When you choose this kit, you get:

Pre-scored trim lines for precise cuts
Self-threading screws and plastic clips for secure mounting
Insulation panel rigidity to prevent sagging over time
Easy-to-clean surface that resists stains and moisture

These features work together to ensure a long-lasting, effective upgrade.

How to Prepare Before Installing DuraTherm Ceiling Liners in RAM ProMaster City

First, we clear the ceiling area of loose debris. Next, we remove any existing trim panels or wires. We also lay down protective floor mats. Meanwhile, we review the Legend installation instructions on Upfit Supply’s product page. Finally, we gather only a Phillips head screwdriver or light impact driver.

Step-by-Step: Installing DuraTherm Ceiling Liners in RAM ProMaster City

Test-Fit the Panels
We place the liner against the roof to confirm fit. Then, we identify pre-scored sections for U.S. and Canadian models.
Trim If Needed
If a bulkhead or partition is present, we follow the pre-scored trim lines. We use a box cutter for crisp cuts.
Position and Clip
We insert grey plastic clips at each mounting point. Next, we slide the liner into place, starting at the rear.
Secure with Screws
We drive self-threading screws through cap covers and into the liner. However, we apply steady, light pressure to avoid tearing.
Reinstall Trim Pieces
Finally, we replace black trim panels and a front 10 mm bolt. This step restores the van’s factory look.

By following these steps, you achieve a snug, gap-free installation every time.

Pro Tips for Efficient Installing DuraTherm Ceiling Liners in RAM ProMaster City

Use Blue Loctite: Prevent screw loosening over time.
Keep Extra Clips Handy: The kit includes spares for peace of mind.
