One and two hours fire rated certified
1. What is a fire check/fire retardant door?
A fire check or fire retardant door is the one that protects us against fire, heat, flame and smoke for 60 & 120 minutes. It is a rectangular frame/structure made of wood, metal or both, previously used for industrial purposes only (e.g. boiler furnace). Nowadays, it is being used in gated communities and multistoried apartment buildings.

2. Why should we use fire doors?
A well designed timber fire door will delay the spread of fire and smoke without causing too much hindrance to the movement of people and goods. Different parts of a building can be separated into compartments of a fire-resisting construction. Any openings leading from them will have fire doors to maintain an effective fire barrier which also prevent excessive transmission of products of combustion which can interfere with the safe use of escape routes.
Therefore, every fire door is required to act as a barrier to the passage of smoke and fire to varying degrees depending upon its location in a building and the fire hazard associated with the building.

3. What are the specific functions of a fire door?
There are two specific functions of a fire door:
1. It provides adequate resistance to the passage of smoke and other combustion products during the early stages of a fire.
2. It provides a barrier to a blazing fire by blocking fire and excessive quantities of smoke from passing.

4. What is the difference between a smoke-stop door and a fire check/fire retardant door?
Smoke Stop Door : Provides resistance only to the passage of smoke and other combustion products. NOT subject to the full severity of a fire because of their location
Fire Check OR Fire Retardant Door : Requires resistance to the passage of smoke AND also blocks fire by containing it and compartmentalizing it. It has to meet both the requirements of smoke and flame resistance.
At present, fire doors are specified as smoke-stop doors when required to fulfil the first function and fire-check and fire-resisting doors to fulfil the first and the second.

5. Why FCD's have become indispensable in sustainable fire risk management?
- To keep exit route free in case of fire or emergency
- To compartmentalize and contain the fire and check it from preaching

6. How to choose the right fire door?

HOW TO CHOOSE?
STEEL FIRE DOOR WOODEN FIRE DOOR
RISE IN TEMPARATURE ON BOTH SIDES TEMPARATURE RISE CAN BE CONTROLLED
BEING METAL. GETS DEFORMED AT HIGH HEAT ALREADY HIGH HEAT AND PRESSURE TREATMENT IS DONE, HENCE CAN WITHSTAND HIGH TEMPARATURE WITHOUT GETTING DEFORMED.
FITTINGS NEED EXPERTISE FITTINGS CAN BE DONE BY ORDINARY MASON AND CARPENTERS
MAINTENANCE IS DIFFICULT , IN CASE OF ANY DIFFICULTY, YOU WOULD HAVE TO CALL PEOPLE FROM THE SAFETY PROVIDERS, YOU ARE TOTALLY DEPENDENT MAINTENANCE IS VERY EASY.BEING A WOODEN DOOR, ANY CARPENTAR CAN HANDLE .
EVEN IN THE BEST OF GATES , METAL DOORS CANNOT ESCAPE THE SOUND THEY MAKE WHEN THEY CLOSE NO SOUND ANYTIME
NO MODIFICATION AS PER EXISTING DE/COR POSSIBLE VERY FLEXIBLE, MODIFICATION AS PER EXISTING DECOR. PAINT, VENEER OPTIONS AVAILABLE.

12. 4 uses of fire insulation door
Fire insulation doors are specialized doors designed to prevent the spread of fire and smoke between different areas of a building. Here are four common uses of fire insulation doors:
a) Building safety: Fire insulation doors are an important safety feature in any building. They can prevent the spread of fire and smoke, giving people more time to evacuate the building in case of an emergency.
b) Fire-rated enclosures: Fire insulation doors are often used to create fire-rated enclosures around building services, such as electrical equipment or heating and ventilation systems. These enclosures can help prevent fires from spreading to other areas of the building.
c) Industrial settings: Fire insulation doors are often used in industrial settings, such as factories or warehouses, where flammable materials are present. These doors can help contain fires, minimizing damage to equipment and property.
d) Multi-family dwellings: Fire insulation doors are commonly used in multi-family dwellings, such as apartments or condominiums, to prevent fires from spreading between units. This helps protect occupants and limit the spread of damage.
Overall, fire insulation doors are an important safety feature in any building or setting where fire risk is a concern. They are designed to withstand high temperatures and prevent the spread of flames and smoke, helping to keep people and property safe in case of a fire

13. How fire doors are insulated
Fire doors are typically insulated using a variety of materials designed to resist the spread of flames and heat during a fire. The specific type and thickness of insulation used in a fire door will depend on various factors, including the door's intended use, the required fire rating, and the local building codes and regulations.
Some common insulation materials used in fire doors include:
Mineral wool: This material is a type of fiber insulation made from volcanic rock or slag that has been melted and spun into fibers. Mineral wool is fire-resistant, as well as being resistant to moisture, mold, and pests.
Vermiculite board: This is a lightweight material made from expanded vermiculite, a natural mineral that is heated until it expands and forms a board-like material. Vermiculite board has excellent insulation properties, as well as being resistant to fire and moisture.
Ceramic fiber: This is a type of high-temperature insulation made from refractory ceramic fibers. Ceramic fiber is highly resistant to heat and fire, making it an ideal choice for use in fire doors.
Intumescent materials: These are materials that expand when exposed to heat, creating a thick, protective layer that helps to insulate the door and prevent the spread of fire. Intumescent materials may be used in combination with other insulation materials to provide additional fire protection.
