structural fire protection

Fire Protective Boards are fitted around the steel columns and beams to form a box and are usually secured by mechanical fixing or by installing "noggins" into the web of the steel. Board Fireprotection systems can offer upto 240 minutes fire protection.

The systems protect the steel by providing a heatproof insulation in some form and the mechanism of this varies with individual formulation of the board.

Using the same method as with the paint (Hp/A) we can calculate the type and thickness of board to provide the correct integrity and it is essential to ensure that the correct board thickness is chosen to give the required period of protection.

Board composition ranges from gypsum-based plasters or calcium silicate, through fibres and specialist vermiculite containing materials. Boards can be left untreated in not in public view, or can be decorated for aesthetic reasons.

roof linings

Where a compartment wall meets a roof the roof may require protection over a minimum distance of 1.5m from each face of the wall. If the roof does not have a continuous fire protection lining the necessary protection can be provided with board lining in Flamebraker Grid. This situation may also be required on external walls.
