UPVC windows, are relatively new to USA. An ‘unplasticised’ form of PVC, these sturdy window frames have been popular in Europe and America for many years owing to their durability and low maintenance. UPVC windows can withstand extremes of heat, cold, wind, rain and snow without corroding, peeling, chipping or flaking.
Considered an energy efficient choice, UPVC windows have similar thermal properties to timber. UPVC limits the transfer of heat and cold through the frame and as a result can reduce reliance on heaters and air conditioners. These frames can also be filled with foam insulation to further improve thermal performance.
