Passive Fire
Protection

Passive Fire Protection (PFP) is a critical part of any fire safety strategy. Unlike active systems such as sprinklers and alarms, passive fire protection works silently and continuously, preventing fire and smoke from spreading through a building. By compartmentalizing the structure and protecting key elements, PFP helps safeguard lives, property, and structural stability during an emergency.

At Milestone Aquatech LLP, we design and implement comprehensive passive fire protection systems that comply with NBC, IS codes, and local fire regulations. Our solutions enhance building resilience while ensuring compliance with fire safety approvals and audits.

Fire Rated Doors

Fire-rated doors are specially engineered doors designed to resist fire, heat, and smoke for a specified time period (commonly 30, 60, 90, or 120 minutes). They are installed in staircases, corridors, electrical rooms, exits, and compartment walls to slow the spread of fire and provide safe evacuation pathways.

Fire Retardent Chemicals

A fire-retardant chemical is a specially formulated substance used to slow down, reduce, or stop the spread of fire. Instead of extinguishing flames instantly, it works by interrupting the combustion process, cooling surfaces, and forming a protective barrier that limits oxygen and heat reaching the material.

Fire Dampers

Fire dampers are critical safety devices installed inside HVAC ducts to stop the spread of fire and smoke between rooms and floors. When a fire occurs, the temperature in the duct rises — causing the damper to automatically close. This seals off the duct and helps maintain the fire-rated barrier of the wall or floor it passes through.

Fire Rated Glass

Fire-rated glass and glazing systems provide transparent fire protection, allowing natural light and visibility while preventing the spread of flames, heat, and smoke. Unlike ordinary glass, fire-rated glass is engineered to withstand high temperatures and maintain its integrity for 30, 60, 90, or 120 minutes, helping protect occupants and critical escape routes during an emergency.

Fire Sealant

Fire sealant is a specially formulated material used to seal gaps, joints, penetrations, and openings in walls, floors, and ceilings to prevent the spread of fire, smoke, and toxic gases. Once applied, it expands (intumesces) when exposed to high temperatures, forming an insulating barrier that helps maintain the integrity of fire-rated assemblies.

Intumescent Coatings & Tapes

Intumescent cable coatings and tapes are specialized passive fire protection materials designed to protect electrical cables from fire and prevent flame spread along cable routes. When exposed to high heat, the material expands into a thick, insulating char layer, slowing heat transfer and stopping cables from igniting or failing prematurely.
