Fire Doors

Acoustic Fire Doors
We are the leading manufactures of fire resistant doors that prevent the spreading of smoke or flames to other areas. These doors are very strong and robust. We manufacture these acoustic fire resistant doors according to the specification of the client based on our assessment of the location of installation. The doors are easy to install and have a good finish.

Material used:
The fire door frame is made of 16 gauge galvanised steel with a bending radius of 1.4mm and the fire door panels are made from two sheets of galvanised steel of 18 gauge each. Encapsulated between the two sheets is acoustic as well as thermal insulation material.

The doors are designed in a way that when closed there is no gap between the door panel and the frame. The frame of the door is as close fitting as possible. Usually the fire doors are self-closing and are fitted with a cold smoke seal which ensures that they are totally sealed not allowing the sound, air or smoke to pass through.Intumescent material is used as a door seal which expands easily in heat and fills any gap between the door and its frame ensuring that the door is totally sealed off.The melting point for the hinges is above 800°C.

Fire doors: Areas of use
Acoustic fire doors have a high usage and most commercial areas should be using them. The general areas of use for fire doors are kitchens, machine and plant rooms, workshops, storerooms, laboratories and service ducts. Other areas where they should be used are as doors to staircases and corridor partition doors in large residential and commercial buildings. In case of a fire the fire door will prevent the flames and smoke from spreading through the exit doors, thus providing a good escape channel.
