If you’re driving a work van like the GMC Savana or Chevy Express, you know how important interior climate control can be. Whether you’re trying to keep tools from freezing in the winter or stay cool during a summer install, insulating your van’s cargo area makes a big difference. That’s why we’re excited to walk you through the unboxing of the AutoPly Cargo Van Insulation Kit for GMC Savana & Chevy Express.

At Upfit Supply, we don’t make this kit, but we do sell, test, and review the products that help our customers get the most out of their commercial vehicles. So let’s take a closer look at what makes this insulation kit stand out—and why it might be the easiest upgrade you make this year.

What Comes in the AutoPly Cargo Van Insulation Kit?

We were impressed by how compactly the AutoPly insulation kit ships. Everything is packed into a single, large cardboard box. Inside, you’ll find pre-cut panels of insulation designed to fit precisely into the walls, ceiling, and doors of your van. This particular kit is compatible with both the 135-inch and 155-inch wheelbase models. If you have the shorter model, you’ll simply have a few leftover pieces.

Each panel is labeled and grouped in a logical order:

  • Driver-side panels and rear doors are placed on top
  • The ceiling panels come next
  • Finally, you’ll find the passenger side and sliding door panels

This intuitive layout makes it easier to identify and install each piece in the right place.

Material Details and Build Quality

Let’s talk about the insulation itself. Each piece of the AutoPly Cargo Van Insulation Kit is made from a material known as AutoWeave™, a fiber-based thermal insulation designed specifically for vehicle interiors.

Here’s what stood out to us:

  • No fiberglass – No itching, no need for protective gear during install
  • R4.0 rating – The 1-inch version offers a high R-value for thermal resistance
  • Mildew- and mold-resistant – Even if it gets wet, it won’t become a breeding ground
  • Hypoallergenic – Safe for long-term use in confined vehicle interiors
  • Meets FMVSS 302 – Fire-retardant and meets industry safety standards

You can also choose the ½-inch version, which offers an R2.0 rating. While it’s thinner and easier to install in tighter spots, we chose the 1-inch for maximum insulation value.

Installation-Ready: Just Peel and Stick

Perhaps the most attractive feature of this kit is how easy it is to install. Every piece of insulation comes with a strong adhesive backing. You simply peel away the liner and press the panel into place.

A few quick notes:

  • The adhesive is very strong, so plan your placement carefully
  • Be mindful not to let the insulation fold or stick to itself before installation
  • No tools, glue, or spray foam required

This kit takes the guesswork out of insulating your cargo van. No need to measure, cut, or make templates. You just follow the shape of the van’s existing panels and supports, and the pre-cut insulation fits snugly in place.

Benefits of Insulating a GMC Savana or Chevy Express

Let’s not overlook the big picture. Here’s why a pre-cut van insulation kit like this one is such a smart investment:

  • Thermal protection – Keeps the van cooler in the summer and warmer in the winter
  • Noise reduction – Helps absorb road noise and rattles
  • Improved comfort – Makes the interior more pleasant if you work inside your van
  • Energy efficiency – Reduces the need to run HVAC systems at full blast
  • Moisture control – Prevents condensation buildup that could lead to corrosion

For contractors, delivery drivers, or DIY van lifers, this kit adds instant comfort and long-term value.

Designed for Fit and Function

Unlike generic insulation rolls, this kit is made to match the exact layout of your Savana or Express cargo van. Each piece is precision-cut to fit the recesses, pillars, and contours of the van’s interior.

For example:

  • Wall panels fit between vertical ribs, aligning with factory geometry
  • Ceiling panels span across roof sections without gaps
  • Door panels contour to recessed metal—and include pieces that accommodate glass or OEM trim

This means you spend less time trimming or adjusting and more time getting the job done right.

Adhesive Performance and VOC Rating

Another standout detail is the low-VOC adhesive used on each panel. Not only is it safe to install in enclosed spaces, but it also delivers a long-lasting bond, even on curved or vertical surfaces.

If you’ve ever struggled with cheap adhesives peeling or failing in fluctuating temperatures, this kit is a game-changer. Once applied, it stays in place.

A Few Things to Keep in Mind

Before you get started, here are a few final thoughts based on our experience:

  • The AutoPly kit includes pieces for both wheelbase models, so don’t worry if you have a few extras.
  • You’ll want to clean your van’s interior metal before applying insulation for the best adhesion.
  • If your van has OEM lower door panels, insulation may not be needed for that section.
  • Watch our installation video if you want to see the real-world install process step-by-step.

Final Verdict

We’re big fans of the AutoPly Cargo Van Insulation Kit for GMC Savana & Chevy Express. It’s straightforward to install, thoughtfully designed, and delivers real performance benefits without the mess of spray foam or cutting bulk insulation.

If you’re ready to take the comfort, efficiency, and quiet of your van to the next level, we highly recommend checking it out.
