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.
