    Tools Needed: Power Drill

      • How does the Insulation Frame get installed?

      We recommend using high grade contact adhesive when securing your insulation frame to the floor of your vehicle.  While fasteners can be used for this, extreme caution must be taken not to puncture your fuel tank and holes must be rust proofed.


      • How does the subfloor get installed?

      The subfloor with insulation frame has pre-drilled holes to guide it into place.  While the included fasteners are sufficient, the addition of wood glue is recommended.  The subfloor without an insulation frame can be adhered (recommended) or fastened in place, just like the insulation frame.


      • If using epoxy- how much do I need?

      We've seen a half gallon as more than plenty for the Sprinter 144.  If using this kit in a Sprinter 170, using one gallon of epoxy may be needed.

      Simple, straightforward, and affordable.

      We build vans and we’ve built floors. We love this floor especially as a base, single layer.

      A clean floor, marine-grade adhesive, and some weight is all you really need to have a solid, simple install that doesn't creak and is strong enough to hold fasteners!

      Excelent u as timer service

      Love their floor kit. Easy install, great price and excellent customer service. Bought the ceiling kit as well. Triple A plus

      What an amazing team!

      Once again, Dmitriy and his team knocked it out of the park! Great product and the after sale service is even better. Dmitriy always calls me back right away and is unbelievably helpful when I have a question or problem. I can’t recommend Serg Supply strongly enough!
