Beginning of energy rehabilitation works. From class D to class C.
Today we begin an energy rehabilitation work of a building in Barcelona (Sarria-St.Gervasi). 12cm incorporated insulation wool flakes and a ventilated air space of 4cm, and improved waterproof breathable waterproofing sheet. Only with this intervention the building goes from class C to class B. These are the interventions of the present and future of our country!
