SIMPLIFYING TECHNICAL BUILDING SOLUTIONS
Simplis – Solutions for modern minimal interiors
The Christo Steel Riser Door. Critical performance. This flush fitting concealed door set protects the building from a shaft based fire that can carry a fire to every level of a building.
Every other fire door in the building protects a compartment. The Shaftwall fire door protects the entire building. With many shaftwall fire door solutions opting for a narrow door profile the Christo Steel Riser Door Range is a full 100mm deep steel reinforced insulated core designed for maximum safety.
The Grenfell disaster sadly demonstrated how a fire can spread quickly via building voids that transverse multiple floors. The Christo Steel Riser/Shaftwall solution is thoroughly tested to protect the riser shaft and contain the fire. This stops the fire from utilising the riser shaft to spread the fire throughout the building.
Christo Riser Door solutions are bespoke manufactured to your project specifications allowing you to choose from a wide range of available options. All Simplis Christo Riser Door solutions are fire tested to BS476:22.
The Christo Timber Riser Door is the result of years of development. Concealed flush fitting framed sets are available up to 60 minutes fire resistance with standard doors sets up to 120 minutes. For the fully concealed riser over 60 minutes we recommend the steel version which is tested to 120 minutes.
