Deceuninck highlights benefits of high-performance windows for energy efficiency

Deceuninck, a manufacturer of PVC window and door systems, highlights that replacing old windows with high-performance models is one of the most impactful interventions for improving residential energy efficiency in Spain.

Efficient windows help minimize heat loss during winter and heat gain during summer, which reduces the energy demand required for climate control. According to the company, this investment improves thermal and acoustic insulation, lowers energy bills, increases interior comfort, and contributes to the decarbonization of the residential sector while increasing property value.

Throughout 2026, various public aid programs managed by different autonomous communities in Spain remain active to encourage the energy rehabilitation of buildings and homes. These subsidies can cover the renovation of exterior carpentry when it helps achieve established energy-saving objectives.
