Swing Door And Window Aluminium Profile
The Swing/casement window is divided into a push-pull type and an overhang type. The utility model has the advantages of large opening area, good ventilation, good sealing performance, excellent sound insulation, heat preservation and impermeability. The inner opening type of window cleaning is convenient; the outer opening type does not occupy space when opened. The disadvantage is that the window width is small and the field of view is not wide.
