| Description
| - Příspěvek se zabývá možností určování tepelné emisivity povrchů stavebních materiálů pomocí měření prováděném v přístroji pro měření součinitele tepelné vodivosti metodou desky. Pro přesná měření spektrální emisivity se používají infračervené spektrometry vybavené měřícím nástavcem s pozlacenou sférou do níž se vkládá měřený materiál. Těchto zařízení však není mnoho a jejich pořizovací cena je značná, proto se hledají dostupnější způsoby jak emisivitu určovat alespoň přibližně. (cs)
- The composition of coating materials, applied in the exterior layers of building constructions, affects the value of emissivity, important for the radiation of ther-mal energy from outer surfaces of such constructions into the free space. In case of most coating materials the rather rugged surfaces do not admit any di-rect measurement, based on the monitoring of the intensity of rays, reflected from the surface. The appropriate approach is the integral measurement of the reflected diffusive radiation from the surface, using the %22ball method%22: its interior sphere for the wavelengths from 5 to 20 ?m must be gold-coated. However, such expensive equipment is not available in the Czech Republic, thus the indi-rect method of the measurement of the thermal resistance of the air gap has been applied where both the thermal flow and the heat radiation are active. The results of such measurements give a chance to evaluate the proportions of both these processes of heat propagation. The paper demonstrates practic
