Straw is an excellent thermal insulation due to the large amount of air retained inside and its high density.
Thatched panels enable the construction of energy-efficient buildings, passive houses (Passivhaus), nearly zero-energy buildings (nZEB) or even positive-energy buildings.
Straw thermal conductivity coefficient = 0,45 W/mK
Wall thermal transmittance with revocation on both sides (inside and outside) U = 0,11 W/ m2 K
Straw absorbs much of the sound waves over a wide frequency range. Thanks to its density, thickness and coating materials it offers a high
