Why we chose it
Warmer in winter. Quieter in every season.
Continuous mineral wool batts and rigid exterior panels deliver an R-24 wall and R-41 roof assembly, with the acoustic and fire benefits stone wool is known for.
Continuous exterior
A rigid outer layer breaks thermal bridges through the studs.
Acoustic damping
Dense fibers absorb interior echo and reduce outside noise.
Moisture-open
Vapor-permeable, the wall dries in both directions.
