I’ve concluded the last post contemplating the real world issue of two different trades (carpenter and insulation installer) working on an insulation assembly at the same time.
How about bringing a third trade into the picture: The plumber.
The outdoor cooking concept
The last room to insulate is the 2nd floor kitchen. Back in the day, I had roughed-in the gas line for the stove, knowing that I need to fine tune this connection once we start framing and insulating.
To add resilience to our design, we plan on extending the gas line to the back porch, which would allow for outdoor cooking during the dog days of summer. Shifting the cooking onto the back porch keeps the unwanted cooking heat out of the conditioned and hopefully cooler building interior.
Installing the the interior perimeter wall framing with the rock wool insulation has become almost routine. Integrating the gas line into the assembly would typically be the last step, similar to what we did on the 1st floor.
However, aligning and drilling the holes through the already installed studs filled with rock wool batts and then fitting in the gas line is like a puzzle you don’t really want to put together. I always wondered if there is an easier way. My friend Drew and I decided to give it a try and represent three trades at once: carpenter, insulation installer and plumber.
Rather than installing the gas line last, we drilled the holes into the studs and fitted sections of the gas line while we were assembling the framing with the insulation.
I am not sure if this was a faster method. But it was easier and more precise with less puzzling. Pre-drilling the studs while we put the framing together made a big difference because it allowed us to perfectly align the holes.
I’ve learned that you have to be on your toes and constantly think and rethink the task sequencing, because layering three trades into one task is, let’s say, unconventional.
The rethinking of sequencing was further complicated by the chimney bump out on the west facing wall. I did not want the framing to follow the bump out. That would make for complicated drywall installation and even more complicated kitchen cabinet fitting.
Instead, we opted to hide the bump out behind the framing. Yet we still had to fit the two layers of rock wool insulation.
Our solution was to frame the wall left and right of the bump-out with two by six lumber. That gave us the three and a half inches to fit the first rook wool layer between the framing and closed cell foam. We framed the chimney bump-out with regular two by four studs with one layer of rock wool. This gave us a continuous wall plane.
I would like to thank our friends Drew and Rubani for their help with the multi-tasking and for putting their minds into this job and keeping me out of trouble!
