Residential Double Hung Sliding Windows
APL 2019 Specifier Guide available Order now
Description

A double hung window is available with two surrounding frame options — one with a scrolled Edwardian appearance and the other with a clean, flat face for a more contemporary look.

These windows have non-projecting sashes; a good choice to keep walkways clear. An easy-clean feature for window exteriors allows the panels to pivot inwards when two corner catches are pressed, especially handy for high level windows.
