1. Standard Insulation Kit

The Budget-Conscious Weekend Warrior

If you’re primarily using your van for summer surf trips or quick weekend getaways, this kit focuses on the essentials: high-quality thermal insulation that fits your specific van model perfectly.

  • Temperature Control: Keeps it cool in the sun and warm on chilly nights.
  • All-In-One: Includes adhesive tape, professional cleaner, and a cutting set.

2. Insulation & Sound Deadening Kit

The Light Sleeper & Adventurer

Ever tried to sleep in a van during a rainstorm? Without sound deadening, your van is a giant metal drum. This kit includes our vibration-dampening barrier.

  • Acoustic Comfort: Stops vibrations and "tinny" echoes before they start.
  • Peaceful Nights: Significantly quieter cabin while driving and sleeping.

3. Premium Insulation & Sound Kit

The "Do It Once, Do It Right" Builder

Our flagship kit using highest-grade materials. We recommend this for anyone planning a full renovation or looking to live in their van long-term.

  • Custom-Fit Precision: Designed for your van's dimensions—less waste, more professional.
  • No Upgrades Needed: Ensure you have the best protection from day one.

No matter the kit you choose, our insulation sets are built to transform your van. We don’t just send you the material; every kit includes a Professional Cutting & Fitting Set to ensure your installation is clean, secure, and built to last.

The Professional Cutting Set

Half the battle of a van conversion is having the right tools. We've included everything you need to get the job done right:

  • Precision Cutting Knives: These heavy-duty blades are designed specifically to slice through our insulation sheets in a single, clean pass. No more struggling with blunt scissors or jagged edges.
  • Sharpening Block: Insulation material can dull a blade quickly. Our included sharpening block allows you to hone your edge mid-build, ensuring every cut is as smooth as the first.
  • Surface Cleaner: We advise using this to prep your van’s metalwork before you start. Removing factory grease and dust ensures the self-adhesive sheets bond perfectly to the surface.
  • Adhesive Tape: Use this to seal the joints between your sheets. This creates a complete vapor barrier, protecting your van’s bodywork from condensation and rust.

Choosing Your Insulation Thickness

Our kits are available in four thicknesses: 10mm, 19mm, 25mm, and 32mm. Picking the right one comes down to three things: where you’re traveling, how long you’re staying, and how much "living room" you want to keep.

10mm – The Space-Saver

Best For: Summer travelers, weekenders, or micro-campers.

Why Pick This: If you primarily travel in fair weather, 10mm provides a solid thermal break without eating into your interior width. It’s also the easiest to flex around tight curves and narrow ribs.

19mm – The All-Rounder

Best For: Three-season travelers and full-time van lifers in temperate climates.

Why Pick This: This is the "Goldilocks" choice. It offers excellent thermal retention for chilly spring or autumn nights while still maintaining a very spacious feel inside the van.

25mm – The Cold-Weather Specialist

Best For: Winter explorers, mountain enthusiasts, or those heading to colder climates.

Why Pick This: If you plan on waking up to frost on the ground, 25mm is your best friend. It creates a heavy-duty barrier that keeps your heater’s warmth locked inside where it belongs.

32mm – The Arctic Grade

Best For: Extreme environments, high-altitude living, or maximum climate control.

Why Pick This: This is for the serious explorer. 32mm provides the highest level of thermal resistance. While it takes up the most room, the peace of mind in sub-zero temperatures is unmatched.

Pro-Tip: Customize Your Build

Can't find the exact size? You can easily add extra sheets or acoustic barriers from our Accessories Section. Many builders choose to "mix and match"—using 32mm for the large, flat ceiling panels and 10mm for the thin pillars to ensure 100% coverage without losing valuable floor space.
