eBook immediate DOWNLOAD - A year's research about what DIY builders are purchasing to insulate the floor of their campervan build. Insulating the floor of a campervan is a personal choice.  Some builders will not insulate because the van floor will always be cold, no matter the insulation.  Other builders install radiant floor heating to solve that problem.  Some campervan builders do not insulate van floors because of the high labor cost of measuring, framing, cutting, installing, and securing the framing to the van floor.    

**  Note:  A vapor barrier with a perm rating of 1 means that in one hour, 1 drop of water 
will pass through the material from the cold side to the warm side.  Materials with a perm 
rating of less the 0.1 (Class 1) is a vapor barrier, while other materials with a higher perm 0.1 (Class 2,3,4) are vapor retarders.   For DIY van builds, it is appropriate to leave a way through venting to let the accumulated moisture dry itself out.   On insulated van floors and ceilings, leave the ridges open for venting.  On insulated walls, leave the weep hole area at the floor open for venting.  

You can use a combination of rigid foam boards for larger, flat areas, and flexible materials 
like Thinsulate, wool for awkward, curved spaces.  Spray foam insulation is another option that creates a tight seal.  The best choice depends on your budget, desired thermal 
performance (R-value), the areas you’re insulating, and your priorities, for durability, moisture resistance, or ease of installation.
