Two-level opening limit may meet demand of ventilation for different time section, i.e. realizing green opening that a little air flow swirls into indoor environment and realizing large area of ventilation and air flow exchange; 360°overturn may provide convenience for wiping glass of elevated building. Pure wood and aluminum-packed wood may meet the demand of the external vertical surfaces of different buildings for decoration effects of door and window. The thickness of frame is 105mm, therefore, according to concrete service environment, Three-layer hollow glass may be applied, the hollow cavity may be assured to have the optimal thickness, so to make window have better heat insulation and acoustic insulation effect. However, due to the limit of five-mental drive mechanism, at present, only products with the following sizes may be provided.
