What's the difference between an inner window and an outer window in a hotel room?

Hotel interior windows are decorative windows maintained for lighting needs and cannot be opened. The outer window is a window that can be pushed out of the room, with good lighting and ventilation. House price: the outer window is more expensive than the inner window, the upstairs is more expensive than the downstairs, the garden view room is more expensive than the corner room, and the exterior view room is more expensive than the garden view room.

Hotel room interior window: Generally, the air conditioner in the interior window room should be set to automatically adjust, which can solve the ventilation problem. And generally speaking, hotels and guesthouses use the rooms with internal and external windows as special rooms. If you live, the problem is not big, and the price is relatively cheap!

The lower part of the humanly scaled opening should be provided with a windowsill. According to the installation position of the window, the window sill can form an inner window sill and an outer window sill. The outer windowsill is to prevent water from accumulating at the bottom of the window opening and flowing indoors. The inner window sill is to remove the condensed water on the window and protect the indoor wall. ?
