Features and Benefits

The multi-chamber design of the Sheffield Window helps trap dead air to produce an effective insulating barrier.
Fusion-welded frame and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration.
Ensuring easy operation, the constant force balance system and heavy-duty operating hardware continue to operate perfectly, even after decades of regular use.
Heavy-duty SteelForce™ reinforcement is placed within the sashes at the meeting rails to ensure extra protection at this very critical and often used location.
The Intercept Spacer System helps reduce conducted heat loss through the window and is better at retaining insulating gas than many conventional designs.
Triple-barrier weatherstripping between the sash and jamb for superior protection from air and water infiltration.
Sloped sill helps prevent water and air infiltration, forcing water to drain to the exterior of the window.
