What is Zip R sheathing, and why did the speaker use it?

Zip R sheathing is a type of sheathing with insulation glued to its interior surface, which helps eliminate thermal bridging and seals the exterior envelope to prevent air leakage.

How does Zip R sheathing meet Oregon's new drainage plane code?

Zip R sheathing provides a 70% drainage rate, meeting Oregon’s code, while Zip roof sheathing provides a 90% drainage rate.

What additional product did the speaker use to enhance wall performance?

The speaker used Benjamin Obdyke’s Home Slicker on all the exterior walls, even between the fascia and subfascia, to provide extra diffusion behind the trim and siding.

What insulation method did the speaker use for their 2x4 walls?

The speaker used closed-cell foam insulation in their 2x4 walls, which are framed on 24-inch centers with stack trusses, to achieve the maximum possible R rating.

Why is using the J roller essential when applying Zip tape?

Using the J roller is essential because it ensures the tape properly adheres to the acrylic coating on the Zip wall and roof, creating a permanent molecular bond that prevents leaks.
