Hygrothermal simulation of building performance: data for Scottish masonry materials

Abstract Retrofitting thermal insulation to solid masonry walls alters their hygrothermal behaviour, which can be modelled by simulation software. However, such software needs values of key material properties ensure satisfactory results and until now data has not been available for Scottish buildings. This work aims contribute a Scotland-specific dataset use designers working on Thermal conductivity, water vapour permeability, sorptivity, absorption coefficient, hygroscopic sorption, density porosity were all determined experimentally selected historic contemporary materials. Within the range materials tested three groups emerge. Natural hydraulic lime mortars, hot-mixed quicklime mortar earth show comparatively low density, high porosity, permeability variable but generally sorption. Craigleith, Hailes Giffnock sandstones, no longer obtained from conservation works buildings, Locharbriggs Hazeldean current production, intermediate these properties. Crathes granodiorite whinstone (from production) It is shown that are relevant buildings constructed in traditional this paper presents first comprehensive set property them.
