building plastic profiles

building plastic profiles length:6.0m Features: 1) Reasonable structure, various models, streamline profile and European groove show the trend of development of modern windows and doors. 2) The design of multi-cavity and multi-layer glass shows the good performance of heat insulation, heat preservation and sound insulation of our products; The four-structure window thermal conductivity k< 2. 0W/m2. K, soundproof can reach at least s35Bb. 3) The windows and doors frames and auxiliary material are put together and sealed by rubber strip and ground strip. Air impermeability <0. 5m3/m. H. 4) The design of material cross section provides itself an independent drainage system which is very useful to drain water. The waterproof ability of the parallel opening windows can reach at least 400Pa and the sliding windows can reach at least 350Pa. 5) The reasonable design of material cross section which strengthens the whole structure ensures various mechanics performance of windows and doors and the products can resist the wind at least 3kpa. 6) Our products are uninflammable things and have good fireproof performance; The material of windows is PVC which has very good insulation performance, and inner lining steels of windows are cut off with each other which will not be closed circuit, so it isn't necessary to prevent lightning during installing the PVC windows. 7) The standard design of window cross section can use general auxiliary materials which are easy for composing produce of the windows .
