ABSTRACT

False ceilings assembled with wooden centerings and camorcanna, safeguard the testimony of an ancient and precious art of building. The paper aims at discovering the benefits, in terms of performance, of this particular constructive system. In fact, the air chamber blocked among the roofing and the false ceiling, unconsciously inherited and planned with the traditional building techniques, appears as an air quantity that can be ventilated in summer and/or contained in winter.

Unfortunately today, the lack of knowledge about such space performances leads architects to blindly operate, dismantling structural and not-structural components of original camorcanna false ceilings. In this manner, not only an unfair action of “elimination” but also an action of “addiction” takes place. Indeed, insulating boards overlie each other to constitute the roofing section.

In the present paper we will discuss two case studies, concerning a townhouse located in Romagna, where camorcanna is widely used in historic buildings. In this Italian region, the practice of eliminating attics by dismantling false ceilings, is particularly diffused. We will compare two models of the same house, one with and one without attic, focusing on the global heat loss values, obtained with the UNI EN ISO 13789:2007 calculation method. The final aim is to demonstrate the benefits of attic on the thermal performance of the building and to assert the necessity to preserve camorcanna false ceilings from extinction.

 

Key-words: false ceiling, camorcanna, traditional building techniques, heat loss, thermal performance.
