The height of the frame, from the top edge of a horizontal 1x4 on the top of the frame, to the bottom edge of the 1x4 directly below it, is 5 feet. Since each 1x4 is actually 3 1/2" wide, the space from the bottom edge of a horizontal 1x4, on the top of the frame, to the top of the 1x4 directly below it is 5' (60") - 3 1/2" - 3 1/2" = 53".
4'x8' sheets of 1/2" Styrofoam were cut to 53" lengths, in order to fit them inside the top and bottom horizontal 1x4s. After that, these 53" pieces were cut so that they would fit inside the space created between the horizontal and verticals 1x4's.
Spray adhesive was applied to the face of each piece of Styrofoam, and then it was pressed against the outside face of the hardboard. After all of the pieces were glued into place, duct tape was wrapped around the sauna, starting at one edge of the door frame and running all the way around each side of the unit until it reached the opposite side of the door frame. This was repeated two more times, to surround the insulation with three horizontal runs of duct tape from one edge of the door to the other.
The insulation fits in between the 1x4's on the sides.
Smaller pieces are needed for the back.
The front needs pieces on either side of the door.
