The Government of Navarra, together with Nasuvinsa, promoted the Efidistrict project with the aim of carrying out a comprehensive energy rehabilitation of the entire neighborhood, on which to later support a regional strategy to promote rehabilitation and transformation dynamics in other municipalities of Navarra.

To insulate the thermal envelope of the buildings, the following ROCKWOOL products have been selected: Ventirock Duo panels for ventilated facades, and Rocksate Duo Plus and the REDArt system for ETICS -type facades. ROCKWOOL rock wool 10 cm thick has provided the facades with continuous insulation, acoustic comfort, energy savings and safety in case of fire.
