Abstract
The European Directive EPB-D 2010/31 / EC provides that, from 2020, new buildings are “nearly zero energy”, whereas existing ones, undergoing redevelopment, already since 2015 must be subject to interventions aimed at energy saving. Efficient and properly installed windows frames are therefore a prerequisite for achieving the goals set by the legislation.
This paper, after reviewing the most recent frontier of laying techniques of the window frames, intends to focus on some issues of unsanitary environments, that their application has produced in this last years, in order to understand the causes and find remedial solutions.
