Thermo-Twin’s windows are constructed with multi-point hinge systems to aid in product functionality. The hinges on each window help with sash movement in particular. These hinges allow window sashes to move near the middle of the frame. As a result, the exterior venting sashes in our windows may be cleaned from inside of your home.
Hinge components incorporated into Thermo-Twin’s windows also do their part to create your perfect look and feel. Hinge systems are color coordinated to your window treatments for flawless appearance and incorporate a single lock for ease of use. The multi-point design also allows for unlimited venting sash positions, giving you the flexibility to obtain perfect home ventilation.
