The advantages of hemp as impact sound insulation

Thanks to the very low dynamic stiffness of our felt, THERMO HEMP® impact sound insulation felt provides very good impact sound reduction (approx. 30 dB with 20 mm felt). Compared to conventional impact sound insulation, THERMO HEMP® needle felt also helps to ensure a pleasant floor temperature.

THERMO HEMP® insulation felts must not be used in rooms that are permanently damp. They should also not be used between two closed films. The construction should be as open to diffusion as possible.
