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 (attached actual pictures).
