Fire stop system launched for curtain wall slab edges
Passive fire protection specialist FSi Promat has launched Paraflam Ultra, a dry-fit slab edge fire stop system for buildings with a curtain walling facade.
The company said Paraflam Ultra is designed to protect the building envelope by preventing the spread of fire around the slab edge for a set period of time in curtain wall facades.
Paraflam Ultra is described as an A1-rated, non-combustible, flexible system.
It is designed to support compartmentation systems by containing the spread of fire from one floor to another.
Testing, movement accommodation and installation details
Paraflam Ultra provides up to 2 hours of fire protection for horizontal slab edges in curtain walling systems.
It is tested to the European standard for curtain walling systems EN1364-4.
Testing also included movement accommodation, with Paraflam Ultra providing up to 6% compression and expansion to maintain the seal between the slab and facade where movement occurs in tall buildings.
As a dry-fit design, the system is compression fitted at the slab edge to reinstate compartmentation and limit fire spread, with the aim of allowing occupants time to escape and fire fighters time to respond.
Range position and specification support
Paraflam Ultra expands FSi Promat’s range of specialist fire stopping and cavity barriers for the building envelope, covering finishes from rainscreen applications to masonry.
Liam Blears, National Commercial Manager for Facades at FSi Promat, said: “Curtain walling is an increasingly popular finish for tall buildings where effective passive fire protection is paramount – and, since façade design is often aesthetic-led, it is vital the fire protection systems used to protect it are kept front of mind during the design stage.
“Through creating a carefully engineered, movement accommodating system, FSi Promat is able to support with this.
“With FSi Promat’s commitment to competent technical support and efficient distribution, Paraflam Ultra can be confidently specified and supports ease of installation.
“It complements the range of cavity barriers FSi Promat already produce to provide fire protection for the building envelope; which now includes mixed façade and curtain wall finishes thanks to the introduction of Paraflam Ultra.
“Alongside the launch, we’re offering specification packs to support in the accurate design of passive fire protection at the earliest stages of a project to ensure best-practice and provide the level of detail needed for curtain wall or hybrid facades.
“Plus, a range of training and extra supporting collateral is in development so watch this space.”
The company said it already offers closed and open state cavity barriers for ventilated and non-ventilated facades, including the Silverliner range.
Specification packs are also available for rainscreen and masonry facades.
