Interior window
Due to the planning of the designer and the special requirements of the interior design, the window is designed for the interior. When it exceeds the manufacturing range, the window can only be placed indoors and is only for the purpose of providing an extra large view indoors. It is not recommended to open it normally, but it retains the function of being an operable window for fire escape purposes. This window must not be placed on the outside and is not guaranteed to have the three properties (water tightness, air tightness, and strength).
