01：French window is to increase the height of the window as much as possible, so that the window can be directly fixed on the floor. This kind of window is called french window.02：A bay window, generally rectangular or trapezoidal in shape, protrudes outward and is equipped with glass on all three sides. There are two types of bay windows: inward floating and outward floating. The outward floating is convex, while the inward floating is flat and concave. The outward floating window is usually made of glass on three sides, protruding from the wall and facing upwards. The inward floating window usually has one glass side and two walls, which is relatively safe, but it will occupy indoor space.03：Sliding windows are divided into two types based on the sliding direction: horizontal sliding windows and vertical sliding windows. Horizontal sliding windows require track grooves to be placed on top of the window sash, while vertical sliding windows should have pulleys and balancing measures. Sliding windows have the advantages of not occupying indoor space, with beautiful appearance, economical price, and good sealing. Using high-end sliding rails, with a gentle push, it opens flexibly. Paired with large pieces of glass, it not only increases indoor lighting but also improves the overall appearance of the building. The stress state of the window sash is good and not easily damaged, but the ventilation area is limited to a certain extent.04：Folding window is a type of window that achieves multi form transformation through geometric folding deformation. Its core features include flexibility (supporting hinge, sliding, and telescopic transformation methods), space saving (reducing space occupation by 30% -50% after folding), and aesthetics (adaptable to modern style architecture). The key technical parameters include folding angle (adjustable from 0 ° to 180 °), sliding rail load-bearing capacity (≤ 50kg/m ²), and service life of telescopic components (≥ 100000 cycles). This design is particularly suitable for places that require dynamic space segmentation, such as commercial exhibition halls, art spaces, etc., which can effectively improve space utilization and enhance visual impact.05：A style of window in folk residential houses. Window sash opening and closing move along a certain horizontal direction, hence it is called a casement window.Side hung windows are divided into sliding and hanging types. Its advantages are large opening area, good ventilation, good sealing, excellent sound insulation, thermal insulation, and anti-seepage performance. Internal opening window cleaning is convenient; The outward opening does not take up space when opened. The disadvantage is that the window width is small and the field of view is not wide.Model making software: 3ds Max 2014 Rendering software: vray3.60.03 for 3dmax2014 If you have any questions, write me: wjjmsn2020@gmail.com .
