The floor of the shipping container is insulated with the UX 2.0 or EX 2.5 standard flat panel. These panels are 48″ x 24″ and are installed in a running bond pattern.
Install the floor panels in the “floating” method without any adhesive. An alternative is to bond the panels in place with a 3/8″ bead of adhesive along dove-tailed ribbing of each stud.
Install subflooring with a gap for expansion. Fasten with standard coarse thread all purpose construction screws. When panels are installed as a “floating” floor, it is important to layout the subflooring so that the long seam of the plywood does not line up with the seams in the InSoFast panels. The short seams should land over the top of a stud.
