A double-hung window features two sashes that slide up and down past one another. The lower sash sits to the interior of the window and has a lock on the top rail that locks into the lower rail of the upper sash. Most modern versions of this window tilt in so they can be cleaned easier. Loewen double hung windows have a hidden tilt-latch system and a concealed balance system that offers the most wood on the interior of any double hung. Windsor double-hungs offer a non-concealed jambliner and a concealed jamb option. The Windsor concealed jambliner is typically available at the price of our competitors non-concealed jamb.
