More cutting, screwing and hanging out under my trailer

My flashing is more or less installed now, which gives the trailer a much different look!

Here I am cutting the sheet metal with electric shears:
It makes fun curly strips of metal!

 Bird's eye view of the trailer with flashing and boards attached to the metal joists

 View of the underside of the flashing. The 1" screws go into the bottoms of the 2x5" boards, which are isolated from the metal by a strip of sill gasket. I will seal the seams with butyl cocking and screws on the overlapping sections (there is a 2" to 4" overlap on all seams)

Here you can see the depth of the floor cavity, the bolts and screws attaching the boards to the metal joists, the strip of sill gasket, and the flashing under it all.


Next up: insulation! I decided on a 1 1/2" layer of durafoam to go on top of the metal, then fill in the rest of the cavity with 3 1/2" of  Roxul. Then I will put a layer of 1" durafoam on top of the whole platform, to isolate the metal joists from the plywood floor decking.
After that... framing. Oh sweet, sweet framing to take me into the realm of the vertical... I so need to go vertical, all this horizontal is getting me down :-D
hehe
