Check out what M. Steven Doggett, Ph.D., Principal Scientist & CEO of Built Environments, has to say about mineral wool absorbing water compared to foil-faced polyiso.
A little preview of what you’ll learn in this study…
“bulk water flow induced by immersion and draining cause fibers to shift with corresponding changes in void volumes. These fiber shifts are likely due to degraded fiber-resin bonds. During repeated cycles, fiber layers begin to separate as slabs become visibly tattered and weathered (Figs 11-14).”
