natureplus criticises ÖKO-TEST magazine's assessment of roof insulation materials

In its August issue, ÖKO-TEST magazine evaluated 15 different roof insulation materials, including 5 with the natureplus seal of approval. The products are mainly suitable for insulation between rafters. The good performance of conventional products made of glass and rock wool, which all achieved "good", was striking. Of the natureplus-certified products, 2 insulation materials made of wood fibres - "Gutex Thermoflex" and "Pavaflex" by Pavatex - achieved the best rating in the test with "very good", while other products only scored "satisfactory" ("Isocell" cellulose fibre, "Thermo-Jute" by Thermo Natur) or "sufficient" (Ziro "Corktherm 040").

ECO criteria do not play a role
However, natureplus Managing Director Thomas Schmitz finds the prioritisation of ÖKO-TEST "questionable". He criticises that the topic of manufacturing energy played no role whatsoever in the test. The use of renewable resources (renewable raw materials or recycled materials) also had no influence on the rating. "This does not fit in with the theme of ÖKO-Test," says Schmitz. The natureplus-tested products, on the other hand, all met high standards in these evaluation criteria, which were not taken into account by ÖKO-TEST.
