Insulated Fire Doors

  • Insulated Fire Doors utilize a double-slat curtain construction with a mineral wool core to combine the fire protection properties of HL fire doors with the benefits of thermal insulation and sound control for openings up to 44′ wide and 24′ high.
  • Insulated Fire doors can be provided with an S-Label as air leakage ratedSmoke Door” assemblies.
  • Fire Door Alarm Releases provide an interface between a fire door and an alarm system/smoke detectors to allow automatic closing to be initiated by the alarm/detectors.  They can be used on new or existing manual or motor operated fire doors (rolling or sliding).  Model  AR-D is a basic fail-safe time delayed release device.  Model AR-D2 includes a battery backup to prevent door closing during a loss of power for up to 7 days.  The Model AR-C converts a new or existing Lawrence “Easy-Reset” fire door operator to “Auto-Reset” functionality providing time delayed alarm activated closing and fail safe closing upon a loss of power, and is automatically reset when the alarm is cleared and power is restored so the door can be opened without any physical resetting of the release.
