  • Load-bearing Birch Plywood subfloor + insulation frame 
  • Sub-Floor cut-to-fit in 3 or 4 (depending on model) 48" x 76" panels
  • Insulation Frame designed to be adhered to the factory protrusions on the base of the vehicle eliminating any need for leveling. Three thickness options allow you to drop your insulation between beams for easy installation. This is cut from 1/2" load-bearing birch
  • The insulation frame + subfloor are pre-drilled to match up seamlessly with countersunk holes
  • Can be adhered or screwed directly into the floor
  • No modification is needed, they're drop-in
  • Lonseal Floor is CNC cut into one continuous piece
  • Loncoin/Lonwood floor is cut to 1/2" wider than the sub floor to close unsightly gaps and corners. This will require minor trimming in several places

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?

    When using in a Promaster 159, we've found that a gallon is adequate.
