Megjegyzések:In this paper we present measurements and measurement methods carried out on construction and building materials in our Building Physics laboratory in University of Debrecen, Faculty of Engineering, Hungary. The investigations with different methods are so significant from the point of view of thermal sizing and designing of the buildings. The laboratory measurements of the thermal properties of materials and in-built structures are very important either for the manufacturers or the designers. In this communication the measurement result are presented. Thermal conductivities will be calculated after steady state thermal resistance measurements both from Calibration hot box (CC) and Heat Flux measurements carried out by Hukseflux (HF) apparatus. Calorific values of some insulating materials will be presented after combusting them in a CAL2K ECO type bomb calorimeter.

Cím:Comparison of the Thermal Properties of Different Insulating Materials / Lakatos, Ákos

Megjegyzések:Currently thermal insulating of the buildings is sorely needed from the point of view ofenergy as well as money savings. It is important to highlight that the most commonly usedinsulation materials in the building sector are the expanded polystyrene (EPS), the extrudedpolystyrene (XPS) and the fibrous (mineral, rock) ones. In this communication we confront 6different insulating materials slabs (EPS 30, 100, 150, 200, a yellow XPS and a mineral wool bytheir thermal properties. Therefore two types of hypothetic building structures were created andwere insulated with the above presented materials from 0.01 m to 0.3 m thicknesses. For thecalculations the thermal conductivity of each sample was determined using a Holometrix 2000(HLS) heat flow meter. As a result their heat transfer coefficients, delaying abilities, energy storingcapabilities and thermal diffusion coefficients were confronted. Besides a material constant hadbeen defined and was paired with the measured thermal conductivity.
