Diathonite Acoustix+

Noise reduction and sound absorption with additional thermal benefits


NRC = 0,75

Average between the frequencies 250HZ, 500HZ, 1000HZ, and 2000HZ which describes the sound absorption performance of a material.


Macroporous structure with high air content that guarantees excellent acoustic insulation performance.

Thermal conductivity

λ = 0,075 W/mK

Thanks to the right mix of raw materials, high thermal insulation performance is achieved.


μ = 4

The high vapor permeability is proof of a porosity that strengthens the acoustic performance.

Fire resistant


Classified in class A1 according to UNI EN ISO 13501-1. No flame generation and no smoke emission.

Mechanical resistance

4,0 N/mm²

High compressive strength capable of giving the wall greater consistency and stability.

Sustainability certifications

Identifies Diathonite Acoustix + as a low environmental impact product with a sustainability that involves all phases of its life cycle.
