PVC profiles are the king of cost performance for assembling a window. It has an excellent Thermal transmittance than Aluminum & Wood. PVC window will help us to save 30% heating or cooling cost. In addition, good Wind load resistant, Air permeability & Water tightness let the PVC window can use for the 10th - 25th floor on building. As people said, PVC windows contain Heavy metal & Lead material. With time passing by, the lead material will come out & harm for health. However, with the development of formula's upgrade, all Lumei profiles is using CaZn stabilizer to avoid any Heavy Metal material. We had passed European CE certification as well as RoHS certification. Besides, Our high anti-UV PVC profiles can keep its virgin color for more than 20 years.
