REHABILITATION OF 4 SOCIAL HOUSES IN SANTA ENGRACIA, BADAJOZ

The Santa Engracia neighbourhood is located in the north area of the city. Built in 1964, the neighbourhood had planned to house those people affected by the floods of the Guadiana River. The maximum period of accupation foreseen was 10 years and, after that time, the neighbours would be relocated in other houses. However, that relocation never came. 

It is a homogeneous urban fabric of 800 one-story single-family houses with a patio, which are accessed through a network of pedestrian streets. Most of the houses have 3 bedrooms, although some are larger and reach 4 bedrooms.

Four of these houses have been selected in this rehabilitation project.

Description of the intervention

a) Façades. An Exterior Thermal Insulation System will be incorporated into the constructive solution of the façades, made up of a rigid panel of expanded cork agglomerate, fixed to the support by mortar with lime and mechanical fixings.

b) Roofs. First, the existing galvanized steel sheet will be dismantled and the existing insulation will be eliminated, replacing it with kenaf insulation with a vapor barrier, mechanically fixed to the existing support.

c) Floors. Due to the configuration of the houses, the original constructive solution of the buildings is not altered.

d) Carpentry. The current windows are made of aluminum without thermal break and simple glass. These will be replaced by wooden windows and double glazing.
