Double Hung Windows – ventilation that you can control.
Double-hung windows operate vertically within the frame so sashes do not
protrude outwards. This ensures walkways outside are easily accessed and that insect and security
screens are easily incorporated into the windows
RWD fit Schlegel spiral balances to our double-hung windows along with
Schlegel seals. This means that our windows operate smoothly and easily when compared to inferior
imported products. This system also allows for large windows, including width, height and weight
to be manufactured therefore allowing for greater design options
