What are Double Hung Windows?
The Double Hung Window is effectively a vertical sliding window that has been used in home construction since the 19th and 20th centuries. Historically the most common design has been the “weights and cords” Double Hung Window, which used a set of counter weights hidden in the frame to offset the weight of the sash.
The “Jambliner” Double Hung Window offers a state of the art mechanism that not only makes opening the window easy, it also allows you to completely remove the sashes from inside for easy painting and cleaning. This is not normally possible with traditional Double Hung Windows.
The Jambliner system incorporated into the window is flush fitted into the side of the frame and does not require painting or maintenance. The Jambliner system also negates the need for containers to hold the counter weights (called mullions). This allows the maximum amount of glass in the frame, therefore more light.
If you are looking for a more ‘Traditional’ style window the “Counter Balance” Double Hung Window combines the look of weights and cords with the modern counter balance sash system, adding that sense of tradition and technology in one package.
The heart of this new system is the counter balance mechanism, which utilises the weight of one sash to counter the weight of the other. By sliding up the inner sash, the outer sash equally moves in the opposite direction. The counter balance system also negated the need for containers to hold the counter weights.
