if you mention the “itch-factor“ I guess you used the Knauf? My understanding is that Aerolite causes some itch when handling it. According to the installer I spoke to, both have the same R-value. How has your experience been since installing the 100mm knauf?
Everyone here seems to be using isotherm, what is the reason for this?
An installer recommended Aerolite or Knauf to me. Has anyone used these? How do they compare to isotherm?
