Top hung is a very popular option for commercial and residential establishments if there is limited outdoor space. In top hung windows we use low-friction hinges operated hardware, which will make them easy to use, long lasting and more secure. Top hung windows have a rubber gasket on the inside and outside of the sash, which means that when the window is closed all the way it is airtight; adding to the insulation properties of your home. Top hung windows create ventilation in any type of weather, as the window tilts open at the bottom and the friction hinges will not rust. The window closes easily with a user-friendly cranked handle. Closed position creates a seal that keeps out sound, heat, dust and cold. The Top Hung window opens outwards. The espag handles give you complete control of how far you want your window to open. Using friction hinges the window can be only open to a certain degree for security.
