The building materials industry classifies interior-insulation-systems increasingly as lucrative market. Here, the swing goes from impermeable material, to open to diffusion and capillary systems. The specially developed plates have the following basic pattern: lime, cement, sand and egg white proteins for frothing. The bulk density is low with values less than 100 kg/m3. This brings good insulation values. With the plates U-values from 0.5 to 0.4 W (m2K) can be achieved. When wall mounting the manufacturer’s instructions should be followed. Continue reading

Original Tadelakt can only be found in one place in the world: in Marrakech. He is very skinny so he can after burning and erasing without aggregates such as sand or grit will be processed immediately.
