Penetration Sealing

Penetration sealing systems work by providing compartmentation in the form of walls and floors designed to protect the occupants of a building by containing a fire in its place of origin for some time.

Subdividing buildings into a series of fire compartments is essential to ensure that escape routes are protected to facilitate escape. As well as protecting from fire, effective penetration sealing prevents the spread of toxic gasses and smoke, and enhances a building’s acoustic and air sealing properties.

Fire Compartmentation is achieved through various means ….

Intumescent Sealants

Intumescent sealant systems are comprised of silicone or water based acrylic intumescent fire protection sealants that work by adhering to a surface and hardening to form a protective barrier from fire, smoke and toxic gasses for up to 240 minutes in gaps up to 50mm wide. AFS Passive Systems install these to manufacturer’s specification, whether that be FSI, Quelfire or Protecta with our operatives competent in using materials from a range of Fire Protection manufacturer’s.

Fire batt

These slabs of endothermic, ablative coated rockwool are used alongside Intumescent sealings to prevent the spread of fire, smoke and toxic gasses through openings in fire protected walls, floors and ceilings, enhancing acoustic performance as well as providing up to 240 minutes of fire protection. Fire batts are a cost effective, lightweight answer to most firestopping problems, including, voids, ducting, cable trays, baskets, trunking and pipes.

Fire Compounds

Fire compounds are a gypsum based fire protection service that provides increased acoustic and thermal properties. These compounds are quick setting and are used to provide a fire seal in compartmentation floors alongside rockwool boards providing up to 240 minutes of protection. Fire compounds are specifically designed where a loading of the penetration is required such as plant room and riser floors. This provides easy, fast installation of an effective load bearing system.

Pipe Collars and Wraps

In the event of a fire, both intumescent pip collars and wraps essentially to the same job – they protect the service penetration at the point where they go through a fire compartmentation wall or floor by closing off the aperture when penetrated with plastic pipes. Whilst pipe collars are surface mounted, pipe wraps fit around the circumference of the pipe within the depth of the substrate. Both systems are lightweight and easy to install providing up to 120 minutes of fire protection.
