ThermoWhite® WD 70 R (R/N) PREMIUM
The new and highest performing product in the ThermoWhite® family. A lambda value of only 0.0381 W/mK brings an unprecedented insulation value.
Achieving the best possible insulation performance with a lower floor construction results in cost savings in materials, installation and energy consumption.

Lambda = 0.0381 W/mK
Live loads up to 10 kN/m²
Compressive stress CS (10) 50 = >50 kPa
Only for use as thermal and impact sound insulation. Not suitable for flat roof, pool backfill.

** The data are to be understood as guide values. A CM measurement is required.
*** A thermal insulation material made of EPS can prevent the spread of fire in case of fire, however, it does not constitute a fire barrier.
**** Minimum thickness to achieve impact sound values. No minimum thickness for all other applications.

ThermoWhite® Ready-mixed products
The ThermoWhite® ready-mixed product is the dry mixture of Thermowhite compound and EPS granules.
Ideal for craftsmen and small quantities, it can be mixed and installed directly on the construction site by adding water in a compulsory mixer.
ThermoWhite® ready-mixed product is mainly used for small quantities, for example for renovations and extensions. Available in bags of 100 and 200 liters.
