Learning from our experience with the single file continuous wall that could only withstand shear forces on the edge, we attempted to abbreviate the usage of rug-screws by using them between the two edges of the wall and by replacing the edge rug-screws with hold-down joints that bind the beam with the ground.  To increase the capacity of insulation, we used the fact that the furniture was manufactured in a factory as an advantage and inserted foam urethane between the studs of the furniture’s interior.
