Abstract(s)
Tabique is a traditional Portuguese building technique using timber and earth and was intensively applied
until the 20th century. There is an impressive tabique heritage that requires maintenance and rehabilitation
interventions. Taking into account the facts that technical and scientific publications related to this particular
technique are lacking and that the technique is also applied worldwide, this research work is a very
relevant one. This study aims at studying the thermal insulation behaviour of tabique walls and in particular,
tabique walls coated using metal corrugated sheets and thermally reinforced with an insulation material.
This type of building component is initially characterized and some building details concerning the metal
corrugated sheet coating are described. An experimental work was conducted to determine the thermal
transmission coefficient of the tabique wall samples. It was concluded that providing the tabique wall
coated with metal corrugated sheets with a 3 cm extruded polystyrene board results in a thermal insulation
improvement of 61%. These results revealed that the thermal insulation reinforcement of tabique
walls is possible and it may be a straightforward building procedure because it can be achieved using the
thermal insulation building materials that are currently being used. Therefore, the thermal insulation
reinforcement of tabique walls seems feasible. Furthermore, the thermal insulation parameters obtained
in this study are similar to the ones obtained for currently applied walls solutions in new buildings. This
technical fact may provide guidance for the possibility of using solutions used in old buildings to meet the
thermal comfort requirements expected in today’s times. The knowledge gained will also be useful to
support future proposals of energy rehabilitation solutions.
