Where do you fit intumescent strips?

In doors, these are single strips that are inserted into recessed grooves in the frame. When the fire causes the strip to expand, it fundamentally complains the door in situation around the edges of the frame to elude distortion and consequently fire seeping by means of the edges.

Fire doors do not march for fire literally burning by means of the door, they are going to essentially fail if the door distorts and bends, letting fire through the edges.

Fire doors in a residential setting are often required in buildings with an adjoining garage door. When the residence exceeds two stories, whether in a new building or even in a retrofit (an attic or basement would count as a story), then fire doors are required to protect the means of escape.

Basically this is to prevent the spread of fire from a room to the stairway. So you would expect most of the landing bedrooms and the room around the corridor on the first floor to be fire doors, usually FD30.

So far so good; it would be very simple to justify this case in any building with a concrete structure, since an ordinary unidirectional slab of joist and ceramic or concrete vault meets this requirement. The problem arises when vertical ducts appear, for example sanitary downpipes (among others). In this case it would be necessary to transfer the REI fire resistance to the finishing element (false ceiling) to be placed on the first floor; in this way the installations would not spread the fire for at least the stipulated time.

FIRE BARRIERSOne of the priorities in the application of the principles of fire prevention is the protection of the property of the neighbors of the building where the fire occurs.  It is for this reason that in cases where a central wall or an element of compartmentalization in fire sectors reaches the roof, the current fire prevention and protection standards require the installation of a fire resistant perimeter strip whose width is equal to one meter with a fire resistance of at least half that required for the roof, fixed to the party wall at a distance less than or equal to 40 cm from the underside of the roof and must be self-supporting and independent of the roof. This strip is called fire barrier and its function is to prevent the fire in one sector from spreading to the other adjacent sectors when the light roof collapses due to the effect of the fire and to prevent the flames from passing over the central wall and with the wind or the air currents caused by the fire from entering the adjacent sector.  Our applicators are experts in the execution of different fire barrier systems:

Fire doors alone will not provide the necessary protection in the event of fire and will only be effective if installed with the correct add-ons and if installed in accordance with the regulations for doors of this type. They work by placing intumescent strips around the edges of the door which remain inactive during everyday use, but when they come into contact with extreme heat, they rapidly expand and seal the gap between the door and the door frame, thus creating a barrier against fire. They can also install intumescent strips with smoke seals to prevent smoke from passing through the door and fire.

However, for a fire door to protect escape routes, prevent the spread of fire and restrict the amount of oxygen feeding the fire, they must be installed correctly and always kept closed.

If you are renovating your home or planning an expansion, it is recommended that you use a fire door for any room where a fire is most likely to start, such as the kitchen, a room with a fireplace, or any room containing electricity or flammables.
