Spectral Emissivity of Roof Membranes and Vapor Barriers

Abstract:

Optical parameters become to the features that are currently taken into account more frequently. There are various reasons of dealing with those parameters. Some of them are due to thermal calculation purposes while the other one are trying to consider low-emissivity functions of various innovative building materials. The paper is focused on spectral emissivity analysis of roof membranes and vapor barriers especially that are applied in sloped roofs and walls with air ventilated cavity. The spectral emissivity in the longwave radiation region was assessed by laboratory method of an infrared spectroscopy. The results present courses of spectral nature as well as its transformation into weighted values. As a result the final comparison demonstrates facts of aiming to point out the possibility of receiving any benefit for thermal aspects purpose.
