A double hung is the traditional sash-over-sash, raise, and lower window. The two sashes overlap near the middle of the window to form a check rail where they lock together. One or two cam-action locks, depending on the size of the window, secure the sashes. A pair of finger-release tilt latches engage the side sash tracks and can be disengaged to tilt the sash inward for cleaning or other access. Locking-when-tilted balance shoes help hold the sash in place when tilted.
Spring balances assist in raising, lowering, and holding the sashes in place when operating. The spring balance system is housed within a pair of vinyl jamb liners.

Exterior-mounted screens are available to help keep out insects when the sash is open. See Screen Options for more information.

Vertical Raise and Lower Sash Operation
Double Hung windows feature a pair of sashes, one hung above the other. The top sash is placed towards the exterior of the window frame, while the bottom sash is placed towards the interior. This allows them to pass by each other when the bottom sash is raised to open or the top sash is lowered to open. The checkrail is the meeting point where the two closed sashes overlap and seal against each other.
Tilt-In Sashes
All Sun double-hung windows feature Tilt-In Sashes. This allows access to the exterior surface of the sash from the inside of the home or building. This can be helpful for cleaning or servicing purposes. Once tilted, the sashes can also be easily removed from the window, again for cleaning or servicing purposes or to open up access through the window opening.
Spring Balance System
The Balance System helps to compensate for the weight of the sash to make it easier to raise and lower. It also helps to keep it in position when you reach the amount of opening desired.
The Comfort-Tilt double hung uses a Spring Balance System housed within our floating jamb liners to achieve this purpose.
Positive Contact Floating Jamb Liners
Our Positive Contact Floating Jamb Liners are a pair of vinyl jamb liners that insert into a pocket on the sides of the window. They have a flexing spring fin on the back that allows them to maintain positive contact with the sides of the sashes. This also functions as a weather seal. The spring balance system is housed within the jamb liner sash guide tracks.
Locking-When-Tilted Sash Balance Shoes
When the sash is tilted to approximately 90°, the balance shoes tighten against the jamb track to help keep the sash stable in that position. This can help while you hold the sash in place. It will also keep the balance shoes in that position if you remove the sash.
