Diathonite Thermostep.047
CORK-BASED LIGHTWEIGHT
THERMAL SCREED
Diathonite Thermostep.047 improves the thermal performance of a floor and keeps it breathable. It regulates moisture and resists mould due to its lime-based alkalinity. It is very workable and can be hand applied or be sprayed on to the floor with a plastering machine.
Cork plays a key role in thermal and acoustic insulation performance with its unique properties – lightness, strength, porosity – the deep foundations of excellence.
Diasen’s Diathonite screed can be used on floors of new builds or retrofits including heritage or listed buildings. It is non-combustible and does not emit smoke so will improve the fire safety of the building.
Thermal Conductivity
λ = 0.047 W/mK
The extremely low lambda implies insulation from both cold and heat, therefore it solves problems related to thermal bridges and guarantees a healthy environment and high living comfort.
Fire resistant
CLASS A1
Classified in class A1 according to UNI EN ISO 13501-1. No flame generation and no smoke emission.
Breathability
μ = 4
Thanks to the high value of permeability (μ), the humidity of the indoors is perfectly balanced, thus avoiding the formation of moulds and condensation.
Thermal Diffusivity
0.124 mm²/s
The low diffusivity value (α) indicates a high degree of insulation from heat and therefore greater comfort and savings for summer cooling.
Density
380 Kg/m³
Its macroporous structure and the use of natural components allows the product to be lighter than a traditional screed. Its performance in terms of insulation and absorption of excess moisture is guaranteed.
Mechanical resistance
5 N/mm²
The presence of natural hydraulic binders, the product is class CS5 certified. It is also CE 13813 certified, thus declaring mechanical resistance class suitable for finishing screeds.
Absorption
∆Lw = 22 dB
L’nw = 58 dB
Thanks to the cork and the porous structure, the product achieves excellent levels of impact sound insulation.
