Materials from renewable natural products. In all sectors, this innovative, necessary development is in full swing, and also in construction. The switchover is becoming a reality at an accelerated pace. The acceptance of, for example, VLAS as high-quality insulation material is a striking example of this. At Isovlas we have long been convinced that it has to go this way. That is why we have put a lot of time, money and energy into biobased innovations for the construction industry. All based on flax.
