Continuous mineral-wool insulation, protected by an air barrier membrane and held in place with strapping, provides a thermal-bridge-free heat control layer.
The crew attached pieces of rigid mineral-wool insulation to the wall using screws and metal discs.
For redundant airtightness and an effective weather barrier, the crew sealed seams in the membrane using SIGA Wigluv tape.
Three-quarter-inch strapping supplies nailing for siding, creates a capillary break for effective drainage of bulk water, and allows air movement for vapor drying.
