NEW, EFFICIENT AND GENERALLY APPLICABLE DESIGN OF RADON-PROOF INSULATIONS-A PROPOSAL FOR A UNIFORM APPROACH
1Faculty of Civil Engineering, Czech Technical University, Thákurova 7, 166 29 Praha 6, Czech Republic.
Abstract:
A comparison of existing methods used for dimensioning radon-proof insulations showed that they generate significantly different thicknesses. As a consequence, they fail to provide relevant information about the applicability of particular waterproofing materials. A new, generally applicable and simple method for dimensioning radon-proof insulation is therefore proposed here. It is based on comparing two values: the radon resistance of the insulation, and the minimum radon resistance. Whilst the radon resistance of a particular insulation can be provided by the manufacturers in technical data sheets in dependence on the thickness and the radon diffusion coefficient, the minimum radon resistance is tabulated in dependence on the radon risk of the foundation soils and the parameters of the building. The new method allows fast, reliable and optimized design of radon-prof insulations.
