A double-hung window is a window that consists of an overlapping fixed outer frame and an up-and-down sliding inner frame. The sliding inner frame can tilt and push out the entire window. Double-hung windows require complex and fine adjustments during installation. The size of the door frame and the size of the sash frame are particularly important, because slight deviations will cause the inner frame to jam. The double-hung windows use air-layer technology, and the bottom and sides need to allow airflow to flow evenly to achieve excellent sound insulation. Can provide excellent sound insulation performance and thermal insulation effect, making the room quieter and more comfortable
A sliding window is a type of window that adopts a horizontal sliding design. The main difference is that it slides along a track instead of translationally. Therefore, it needs to plan the sliding track in advance, so as to ensure the sliding performance of the window. Sliding windows also have many practical features, most notably, they are easier to maintain and clean. Sliding windows that slide side to side also prevent nearby objects from blocking the window. It can make the room truly feel natural, as well as provide better listening and ventilation effects.
