Definition. Straw panels are the cheapest roof insulation but too thick for the standard. At €10/m² they are the cheapest roof material in the study, with low CO₂ emissions of 3.3 kg/m² and 55% reuse. But reaching the required insulation value needs 251 mm, while the model dwelling has only 160 mm of space.
That is why the choice in this dwelling falls to the thinner flax board. New Economy’s circular insulation study for Amsterdam reports this.
