Fire-teK Insulation


Passive structural fire protection is one of the most important factors in HVAC. Highly efficient insulation together with appropriate fire containment is necessary in order to prevent the spread of flames and smoke to other areas of the building.

Horizontal/Vertical rectangular ducts

Properly insulating ventilation ducts is key to containing fires in partitioning areas.  These ducts often pass through building compartments which is breached, can allow rapid spread of fire inside the building. Efficient ventilation insulation reduces the need for mechanical methods of fire protection such as sprinklers.
