Aico has launched fire-rated air valves to its Firecap range of intumescent fire safety products

The company has said the valves are designed to allow air flow from ventilation systems while also providing a 60-minute fire barrier in ceilings. Available in 100mm and 125mm diameters they are tested to BS 476 British Standard Tests level for fire. The firm adds that the valves are fitted without any need for adhesive material or special fixings and can be retrofitted inplace of existing valves.
