Abstract

Soundproofing and heat insulation of a building façade depend on the performances of each element, which forms it. Glass surfaces, which could be considered the “weak” elements of a façade, have to be studied with attention in order to avoid more heat dispersions, thermal and acoustical bridges. The Italian Decree DLgs of 2005 August 19th n° 192 “Accomplishment of the Directive 2002/91/Ce about the energetic output in building” with Enclosure C fixes the thermal transmittance values of the transparent locks, determined on the bases of the Climatic Area. Regarding the acoustical performances, the DPCM of 1997/12/05, “Determination of the passive acoustical requirements of the buildings” defines the evaluation indexes measured in situ following the ISO 140 and ISO 717 standards, which refer the evaluation index of the façade to the reverberation time (D2m,nt,w), which is influenced by the presence of doors and windows. The aim of this work is the study of the thermal and acoustic performances of doors and windows, considering a real case of a terraced building. The study is carried out analysing the total performances of four door and window typologies, according to the 2000 UNI EN 12207 and the 2005 UNI 11173. Finally, the evaluation of energetic costs is presented.
