They highlight the use of modern building materials like the Huber Zip system, insulated radiant slabs, and Zip R sheathing to meet Oregon's drainage codes and prevent air leakage. The walls are framed with closed-cell foam insulation for maximum R-value, ensuring the shop remains energy-efficient for future generations. Attention is given to proper installation methods to guarantee durability and weather protection.

Takeaways

  • 🔨 The speaker built their shop to be comfortable and sustainable for long-term use.
  • ❄️ The temperature difference between Southern California and Southern Oregon was a major factor in the shop's design, with winter temperatures dropping to 20°F in Oregon.
  • 🏡 The shop is intended to be energy efficient and useful for future generations, possibly for their daughter or other woodworkers.
  • 💡 The speaker used an insulated radiant slab for efficient heating, ensuring long-lasting comfort and sustainability.
  • 🧱 The walls and roof are constructed with Huber Zip system sheathing, which includes acrylic flashing tape and specific installation tools for airtight sealing.
  • 🌡️ Zip R sheathing was installed to reduce thermal bridging and improve insulation by sealing the exterior envelope against air leakage.
  • 🏠 Zip R sheathing meets Oregon's new drainage plane code, with a drainage rate of 90%, surpassing the required 70%.
  • 🔧 The speaker used Benjamin Obdyke's Home Slicker for extra diffusion behind the trim and siding, especially with pine materials.
  • 🌳 The shop's walls are framed with 2x4s on 24-inch centers and insulated with closed-cell foam for maximum R-value and energy efficiency.
  • 🛠️ Proper use of the J roller is critical when applying the zip tape to ensure it adheres correctly and prevents future leaks.
