Recently I made changes to how the attic would be built and finished the final wall that separates the attic from the loft.<\/p>\n\n\n\n

\"\"<\/a>
With no ceiling in the attic space, it will be easy to hang the HVAC equipment from the steel above.<\/figcaption><\/figure>\n\n\n\n

After many iterations and much consulting with Adam and Peter, I was starting to think I needed to use whatever space above the attic I could to make the ceiling taller. Eventually Adam suggested I leave it open and just insulate the walls and floor really well. Brilliant.<\/p>\n\n\n\n

\"\"<\/a>
The equipment will be in a semi-conditioned space, but since I’m using all insulated plenums and ductwork it won’t cause any problems.<\/figcaption><\/figure>\n\n\n\n

Having permanent access to the space above the structure also meant I could push back many tasks that were blocking closing up the ceiling and will have more access for maintenance in the future without having to rip up finished walls.<\/p>\n\n\n\n

\"\"<\/a>
The wall is angled, sits between a level subfloor and a vaulted ceiling and has 2×12 let in on one end to distribute the weight, making these boards very complex to cut.<\/figcaption><\/figure>\n\n\n\n

Though small, this is the most complex wall in the build. I checked measurements between the model and the building and then crafted the 2×6 studs for the angled wall.<\/p>\n\n\n\n

\"\"<\/a>
I also ripped the 2×12 at the same angle as the wall to maximize surface area where it makes contact with the attic floor joists.<\/figcaption><\/figure>\n\n\n\n

The design places the studs directly beneath the rafters but the wall and subfloor below have a different pattern entirely. To overcome this, I used a spare 12ft 2×12 to distribute the downward force along the subfloor evenly.<\/p>\n\n\n\n

\"\"<\/a>
The load capacity of the original wall would have actually been sufficient, but I wanted a wider margin of error and 2x4s are cheap.<\/figcaption><\/figure>\n\n\n\n

The wall below was originally framed with 2x4s, 24 in. OC. Now that it’s a load bearing wall, it needed to be strengthened. So I sistered in additional 2x4s to increase the wall’s vertical load capacity.<\/p>\n\n\n\n

\"\"<\/a>
I cut the rafters back using a new reciprocating saw blade called “The Axe” which was shockingly effective at ripping through wood.<\/figcaption><\/figure>\n\n\n\n

Then I framed the wall and removed the remaining rafter segments to open up the attic.<\/p>\n\n\n\n

\"\"<\/a>
One the left side of the attic is an opening large enough to easily get 4×8 sheets of material into the attic. This will be very handy for the rigid foam board insulation I’ll soon be attaching to the top of the rafters.<\/figcaption><\/figure>\n\n\n\n

Finally, I terminated the rafters with a 2×10 and sheathed the back side of the wall with OSB to add shear strength and provide a backer for the closed cell spray foam that will go into those cavities.<\/p>\n","protected":false},"excerpt":{"rendered":"
