Product images
Manufacturer's product description	Liapor Blähton 4/8 oder 8/16 gebunden mit Zement. Die Schüttung ist hoch druckfest (CP = 0,20 mm, Druckfestigkeit = 0,5 MPa), nicht brennbar (A1) und sehr stark wasserdurchlässig.
Processing	Fundatherm kann über den Baustoffhandel und Transportbetonwerke bezogen werden oder auf der Baustelle selbst gemischt werden. Mischrezeptur: 1000 Liter Liapor 4/8 oder 8/16 + 100 kg Bindemittel + 80 kg Wasser. Die fertige Mischung wird eingebracht und auf das entsprechende Niveau abgezogen. Nach der Austrocknung kann der weitere Aufbau stattfinden.

Building physics values
λr thermal conductivity rated valueAUT Austrian rated heat conductivity value. This value is to be used for thermal performance calculations (energy performance certificates, etc.). Definition for insulating materials: A value that is not exceeded by at least 90% of production (probability of acceptance 90%), valid for an average temperature of 10°C and the state of equilibrium for humidity at 23°C/80% relative atmospheric humidity. Source: ÖNORM B 6015-2 Proof: - Nominal value from the CE Declaration of Performance with corresponding humidity conversion factors - Nominal value from the European Technical Approval with corresponding humidity conversion factors - test certificate for the rated value in accordance with ÖNORM 6015-5	0.115	W/(m·K)
μ Vapour diffusion resistance factor The water vapour diffusion resistance (μ value) is a parameter to determine the exchange of moisture of a construction material. The lower the μ value, the easier it is for vapour to penetrate a substance. Definition: Ratio of the vapour diffusion coefficients of the air and that of the relevant substance. Proof: Manufacturer information	5
