Fire Protection to Ductwork READ MORE

London's leading and independent specialist passive fire protection contractor

SIV Fire Protection is providing expertise in all types of Built-in fire protection and passive fire protection solutions.

Fire-stopping to ductwork or high voltage cable trays/ ladders  

In a commercial fire, 240 minutes’ fire resistance can protect your investment, safeguard your insurance and save lives.

When it comes to ventilation and smoke-extraction ducts and their beams and supporting walls, we have fire-stopping measures that can do just that.


Fire-protection boarding

We fit the UK’s leading fire-protection boarding. With a calcium-silicate composition, it offers better moisture resistance that’s suitable for even the hottest environments.

The boards come in a number of sizes and thicknesses to provide fire protection for applications that include internal partitions, ceilings, floors, roofs, door upgrades and boiler backers. You can even opt for door facings, thatch protection and bevelled ceiling tiles.


In partitions and walls, you get light, slim, fast installation in constructions up to 15 metres tall. Above that height, we can offer a bespoke solution.


For ceilings and roofs, our boards are suitable for soffits, fascias, thatched roofs, timber floors, mezzanines and protected zones.
