Abstract

This paper aim to define and systematize some aspects concerning knowledgement and use of recycled building materials; with this aim, the insulation materials have a key role are low energy design and, consequently, in the reduction of environmental impacts. The energy performance of the vast assets of these materials has been compared to highlight their viability of use in comparison with conventional thermal insulation materials (natural or not). To do this, we need to define a methodology for data selection that were the most rigorous possible (bearing in mind the missing systematization of numerous materials by the technical standards and, conversely, the presence of numerous data in commercial product schedules). The comparison of insulation material has to be made, not for all, both on materials than on technical elements. The first results have allowed to highlight that the insulating recycled materials have performance qualities such as to constitute an alternative to any other insulating material and a physical-chemical varieties that have a technological application often wider than that of only natural insulation materials: recycled insulating materials can be used in all the technical elements that define the building envelope (vertical, horizontal and inclined closures). On the basis of the heat capacity and diffusivity values , most of the insulating recycled materials have, in hot clima, worse thermal performance but propensity of heat accumulation with the exception of the products derived from recycled polyethylene (PET) and the recycled rubber; consequently these two materials had been investigated, as first approach, by carrying out an initial analysis of their thermal behavior in a building wall.
