The wood fiber insulation was tested in two variants; batt insulation and loose-fill, both from a German producer [3]. The batt
insulation has a density of 50 kg/m3, while the loose-fill normally has a density between 38 – 45 kg/m3. In addition to wood fibers
the products contains polyolefin fibers and ammonium phosphate. For other properties and the rest of the materials, see Table 1.
For more information about the smart vapour barrier see product information from the producer [4]. The loose-fill insulation was
blown into the cells as described by producer. Of the 15 cells; eight had wood fiber batt insulation insulation, three had loose-fill
wood fiber insulation insulation and four had glass wool insulation.
