Kalamein Lot-Line Windows
For conditions that require a fire-rated window, Capitol Fireproof Door manufactures a 45-minute BSA approved kalamein steel-clad lot-line window. Lot-line windows are primarily used as a fire barrier between two buildings that face each other. They are used in apartments, hallways, stairwells and roof bulkheads. Kalamein windows contain fired that may spread to adjoining buildings. Our lot-line windows utilize a fusible link, which when heated to a certain temperature, melts and drops the window sash to a closed position, which contains the fire.
Top or bottom kalamein sash can be fabricated and retro-fitted into existing kalamein windows. This allows the sash to be replaced without having to replace the entire window.
Many Options Available
Our windows are certified by the NYC Board of Standard and Appeals, for which we were granted the following fireproof label:
This fireproof label certified that our windows meet or exceed fire test standards for New York City and have been approved by the NYC Department of Buildings. The labels, which indicate the “calendar number” corresponding to the NYC Department of Buildings testing results, are affixed to our windows as part of our service.
