Posted By: Mike GeorgeIn terms of comparative vapour and air resistances, are you suggesting that mineral wool and the 'quilted multifoil' used in the shack tests had exactly the same values for vapour and air tightness?Near enough - as in averagely gappy and/or holey, as was the norm back then. I did a little calc, that the total area of the lots of little holes for quilting (measured from a sample) was equiv to one 80mm diam hole per m2! Might even have been worse than the min wool shack.
Posted By: Mike GeorgeI don't know the history of what was used when and where.The Actis 9 product of that time, which the test referred to, was definitely stitch/quilted - they briefly offered a spot welded alternative called something else but withdrew it.
