Renovating a home in L'Eixample or Ciutat Vella in Barcelona is subject to Spain's **Technical Building Code (CTE)**. This framework outlines the criteria for structural safety, energy conservation, and insulation.
1. Energy Savings (DB-HE) & Thermal Performance
Comprehensive renovations must lower energy usage. We install high-performance argon-gas double glazed windows and thermal wall insulation to meet DB-HE rules.
2. Noise Insulation (DB-HR) Standards
To comply with DB-HR guidelines, we apply acoustic band isolators to drywall metal studs, minimizing vibration and acoustic transmission between flats.
3. Structural Safety (DB-SE) and Licensing
Knocking down walls to create open-plan concepts requires structural calculations under DB-SE. We submit engineered plans to the Ajuntament for municipal permits.
