Moisture-buffering plaster «sucks up» water vapour
Empa researcher Thomas Stahl developed the new buffering plaster together with Sto AG. | |||
The new wall plaster that Empa building physicist Thomas Stahl was looking for needed to be humidity regulating, mineral-based, easy to use and not much more expensive than alternative products. The newly developed moisture-buffering plaster can in fact absorb 90 g of water vapour per square meter, measured by the standardized «Nordtest» method. This exceeds the capacity of the best clay rendering, measured for comparison purposes, by about 30 per cent. No more condensing water on thermal bridges | |||
