DiamondPly Insulation Kit for Mercedes Sprinter

Most insulation is just the first step — then comes paneling to protect it. DiamondPly changes that.

This insulation kit for your Mercedes Sprinter is built with a reinforced diamond-pattern surface that’s tough enough to be your finished interior. No extra wall or ceiling panels required. No worrying about snagging insulation on tools, materials or daily use.

That means fewer steps, less cost and a faster path to a clean, professional-grade mobile workspace.

Built to Work — Not Just Sit Behind Panels

Traditional insulation like FiberPly needs to be covered to prevent damage. DiamondPly is designed to stand on its own. The durable polypropylene reinforcement layer resists punctures, snags and wear, while also helping protect your van’s interior from dings and scratches that come with real work.

• No paneling required: Functions as both insulation and finished liner
• Snag-resistant surface: Holds up to tools, materials and daily use
• Interior protection: Helps reduce dings, scuffs and scratches inside your van
• Thermal and acoustic insulation: Keeps your workspace quieter and more comfortable

Installer-Friendly, Jobsite-Ready

• Installs directly to walls and ceilings — no complex buildout required
• Flexible 1-inch material conforms to vehicle contours
• Keeps wall and ceiling structure accessible for future upgrades
• Low-VOC adhesive with strong bond across extreme temperatures

This is insulation designed for how tradespeople actually use their vans — in and out all day, tools shifting, materials moving, work getting done.
