Stud wall completed.

In early February we finished the stud wall that was required to line the angled wall as it was difficult to run the top hat with just the portal frames and then against the door frame. So that flimsy Rondo stud framing was installed and the Villaboard and Termiflor does end up giving it some rigidness.

The wall was sealed as per the rest of the walls and joins.

For some reason, I don' t have a photo of the wall partially built, but you can see the stud framing on the far left of this image.

Adding some climate comfort.

Two Mitsubishi Heavy Industries cooling only split systems were purchased to install on the eastern wall of the train shed. Two Unistrut based brackets were fabricated and mounted to the eastern outside wall to support the compressor.

The Unistrut frames on the east wall.

The internal was primed and painted prior to the condenser units being fitted.

Sunshade / drip and rain roofs were also installed to protect the outdoor compressor units.

The indoor units fitted off and operational.

The outdoor units with the sunshade / rain roof lowered to the correct position.

Top Hat goes around, and the lining goes up!

Finally, near the end of November 2024 I was able to get some further progress and run the top hat rails around the internal walls and insert the Earthwool and line the walls. I had a chippy mate assist me with that. You will notice from the images that I have used Villaboard, or cement sheet, to line the bottom of the internal wall. This came about as the 100 Year Flood Level for Port Hedland is about 20 inches, or 500 mm above the floor level in the shed. So, as a worst case scenario, a major flood of the town from coastal inundation caused from a very bad tropical cyclone should, at least, not lead to any wall damage.

Five top hat rails up around the walls with the batts installed between the Thermalbreak and the top hat.

As the top hat is screwed to the portal frames, when it came to the north wall they were required to be offset as this image shows.

With the cement sheet, to reduce the mucking around with cutting, waste, etc we just installed full sheets and then overlapped the Termiflor. The Termiflor sheets at 3600 x 800mm. These sheets were cut in half and butted up to the ceiling so provide an 1800 mm drop from ceiling height that is 19 mm thick. This also adds to the thermal rating and allows pretty much anything, within reason, to be just screwed straight to the wall without trying to find studs or other anchor solutions.

During some 40 plus degree days the shed only got to around 32-33 inside whilst outside was 45-46 degrees. This was before the air conditioning units were installed.

To continue with the hermetically sealed concept, the wall was sealed to the sealing, the overlap where the Termiflor and Villaboard was likewise sealed and then the Villaboard was sealed to the floor slab and the butt joins were also sealed. As the Termiflor is a tongue and groove join, and will be painted, these joins were not sealed apart from where gaps were present.

Next up, providing some climate comfort...
