The I-60-SW is NZFD’s interior 60 minute fire-rated window unit in a timber frame.

The window achieves the -/60/60 or -/60/30 rating, which means the system will maintain its integrity and insulating qualities in a fire.

Available in a wide range of pane combinations. The window can be either a single window, door sidelight, door overlight, or a glazed internal partition. Mullions and transoms are required for large glazed areas.
