They are manufactured using a high grade virgin uPVC and are engineered so that heat is kept inside the home in winter and outside the home in summer. This reduces heating and cooling costs, minimizes energy consumption impacting the environment, and limits the size of the HVAC equipment required for keeping the home comfortable. In climates that mainly require cooling, windows have represented a major source of unwanted heat gain. In recent years, windows have undergone a technological revolution.
