As suppliers of passive fire protection we often fall into the trap into thinking that everyone knows as much as us about intumescent strips. Obviously this is not the case,
At Noberne Seals we offer a comprehensive range of fire rated fire grilles that are ideal for use in public buildings or business premises. When protecting a building against fire and the reducing the spread of fire a building not only needs to contain fire resistant walls and floors, but also be well ventilated. Natural ventilation systems can often fail during a fire; therefore it is necessary to install a fire grille ensure full protection.
During a building fire, the fire grilles are designed to provide a barrier to restrict the flow of hot gases and smoke through a building. This works by the grilles slats swelling to many times their original thickness and then fusing together. This creates a barrier that provides fire resistance to match the surrounding construction. Normally the fire grilles will allow normal airflow to continue around a building. Our ranges of grilles are tested to 30 - 60 minute fire resistance.
Our choice of fire grilles are available in a number of different sizes ranging from 150mm x 150mm x 40mm (which offers ventilation of up to 153cmsq) to 300mm x 300mm x 40mm (which offers ventilation of up to 614cmsq).
