They are also highly recyclable, making them an environmentally friendly choice.
Q2: Are aluminum windows energy efficient?
A2: Absolutely! Modern aluminum windows, especially those from the best aluminum window brands like Reynaers, Schüco, or Idealcombi, incorporate advanced thermal break technology, which significantly reduces heat transfer. When paired with high-performance glazing, they can achieve excellent U-values, contributing to significant energy savings and meeting strict passive house standards.
