Building a Simple Passive House, Images 28-33

Holes bored in the rafter blocks provided access to the closed framing cavities after the drywall had been hung.

The insulation contractor used a long PVC wand — inserted to the end of the cavity and slowly withdrawn as material was blown in — to maintain a consistent density for the full length of the rafter cavities.

The remaining cavities were filled from inside the building, after it had been determined that the drywall was dry enough to resist bulging or tearing at the screws.

A drop ceiling above interior partition walls provided space for the ERV and associated ductwork.
