Because they open up instead of out, single-hung windows don't take up exterior space when open. This makes them ideal for areas like adjoining walkways, porches, patios and other high-traffic areas. AMSCO® single-hung windows offer the added security of the exclusive AMSCO StyleLockTM or SentryLock, built to exceed every industry standard for forced entry. And our high-quality block and tackle balance spring system allows for simple, seamless operation.
Single-hung windows differ from double-hung windows due to the fact that the upper sash is fixed and the lower sash is moveable.
Artisan Series features the new SentryLock, an automatic, magnetic-action lock.
Traditional and Legacy Series feature the exclusive StyleLock with its popular locked/unlocked visual indicator.
