Fire Rated Doors

INTRODUCTION :

The fire retardant door is designed to delay the spreading of fire from the room where the fire starts to other rooms by different time of rating starts from 30 minutes up to 120 minutes for the main purpose to save the lives of the people.

To control the damage of building and its properties to the minimum limits.

Usually these doors are designed by the consultant’s architect who designs the building depending on number of people using the building lengths of its corridor, and number of floors. From this factors the architect can decide model of door and rating time which needed and enough to let the people to escape from the building and keep good time for the civil defense personal to kill the fire.

MATERIALS :

1- Door leaf Panel:

The panel of the fire retardant door leaf is made of tread & pressed chip board supplied by Halspan and certified by BM Trada, containing special chemicals to withstand the fire for the specific time. It contains three different density of layers with good chemical properties to fit for perfect work like glazing, artistic work.

2- Door Jamb : Made of hard wood with density 650 kg/ cubic meter from beach, cherry, oak, Red Mahogany… etc.

3- Intumescent tubes smoke control system which has very important function such most of the deaths happened from the poisonous smoke and this system it controls the spread of the smoke from the room location of fire to the corridor, next room, other area which that allow the people to see the path to escape from the building.

4- Accessories : It has good specification, tested for fire retardant door and fixed with seal for which not allow for smoke to pass to other area and not conduct any kind of heat.

5- Glazing glass : we are using reinforced, treated and tested, fire retardant glass.

TYPES OF DOOR :

1- 30 Min. Fire retardant door , panel 44 mm thick.

2- 60 Min. Fire retardant door, panel 54 mm thick.

3- 90 Min. Fire retardant door, panel 64 mm thick.

4- 120 Min. Fire retardant door, panel 64 mm thick which consist of one layer core at center from Halspan Chip board with two layers from GRG (Grouted reinforced gyps) for both side plus two layers from MDF; to treat the surface to receive veneer and painting, all of this layers are bonded by special fire rated glue.

MANUFACTURING :

All processes and materials are certified by BM Trada and all processes since incoming material up to final assembly in the site are clearly documented including Main drawing, shop drawings and installation instructions. Finally after completion of installation of fire retardant door will affix Q mark from Q mark from BM Trada approved stickers.

ACTION DURING FIRE :

When the room temperature reaches to 100 ^oC smoke control system of the door will starts its work. By expanding the smoke seal which made of Silicate Potassium, it will close the door gaps; between the door panel & door jamb/ frame, (which are necessary for opening at normal use) closing function of door and stops the smoke to spread out side.

The door panel treated chip board is also a fire retardant material; chemical components, will stops the fire for its specific duration. Likewise all the smoke and fire are controlled in the particular room where fire starts, as per the specified rated time / duration so that less property damage / escaping the people in other area are being safely.

Again we conform that All of our fire retardant doors materials are certified by Q mark from BM TRADA.

ARTISTIC WORK :

All doors can be decorated by fine finished materials like natural veneer, glazing… The doors can be used not only for the living room also for lifts, staircases, kitchens, etc. Also these doors allow opening to make vision options.
