  • Aluminum profiles will not fade under extreme weather conditions, nor will the warp and rot like wood, nor will they rust like steel. This excellent feature ensures that aluminum doors and windows can maintain their structural integrity for a long time.

  • In recent years, the focus on energy efficiency has become increasingly crucial, especially with rising energy costs and environmental concerns. Aluminium profiles can be insulated using thermal breaks—materials that prevent heat transfer. This innovation significantly improves thermal performance, reducing heat loss in winter and minimizing heat gain in summer. With proper insulation, aluminium windows can meet or exceed energy efficiency standards, contributing to a more sustainable building design.
