What Are UPVC Folding Windows?
UPVC folding windows are designed to fold open like an accordion, creating a seamless transition between indoor and outdoor spaces. Unlike traditional sliding or hinged windows, folding windows stack neatly when opened, maximizing airflow while maintaining security and weather resistance. The UPVC material ensures longevity, low maintenance and energy efficiency, which makes them a popular choice for homeowners worldwide.
