Acoustic plaster Diasen®

Diasen offers breathable products for the insulation of walls, interior or exterior, characterized by high efficiency, high permeability, high performance and by the best thermal conductivity value.
The products can be used for heat insulation and cooling insulation, providing an excellent thermo-hygrometry, a long-lasting insulation and allowing the achievement of a high comfort and welfare housing in full compliance with technical standards.
The versatility of Diasen insulating products allows them to be used for new construction, for old construction, for renovation and energy requalification, for facades and partition walls.
The acoustic performance of porosity
Diathonite Acoustix formulation components have a high level of porosity that improves the sound insulation and sound absorbing performances of the product.


μ = 4
Walls are free to breathe, thus leading to permanently dry façades. Thanks to the high permeability coefficient, indoor humidity is perfectly balanced, preventing the formation of mould and condensation.
Thermal conductivity
λ = 0,083 W/mK
Thanks to the right mix of raw materials, high thermal insulation performance is achieved.
Fire resistant
Classified in class A1 according to UNI EN ISO 13501-1. No flame generation and no smoke emission.
Mechanical resistance
5,30 N/mm²
High compressive strength capable of giving the wall greater consistency and stability.
Thermal resistance (R)
0,120 m² K/W
A high level of thermal comfort that guarantees a permanently dry wall.
NRC 0.60
αw = 0.65
Average between the frequencies 500HZ, 1000HZ, 2000HZ and 4000HZ which describes the sound absorption performance of a materia
A macroporous structure with a high air content that provides excellent acoustic insulation performance.
