Historic Replica
Manko’s 3100i series projected window has been specifically designed for the historic replication of steel sash windows. Care was taken to keep sightlines in line with National Park Service historical preservation profiles. The 3100i uses 24mm polyamide crimped‑in‑place structural thermal barrier in lieu of the traditional two-part poured and debridged system. This allows for superior thermal performance while maintaining structural integrity.
Grid Options
When a historic or divided lite aesthetic is desired, Manko’s 3100i series projected windows offers a removable grid option with several grid profiles to choose from. Cove profiles are frequently used with Manko’s 3100i to replicate a steel sash window.
