The Coopers SmokeStop® Concertina™ is a multi-side smoke curtain that has been developed to provide high performance smoke protection to EN 12101-1 without the need for side guide channels that would terminate into columns or corner posts.

The SmokeStop Concertina “closed ” system is bespoke to each project and is available in closed shapes, such as squares and faceted circles, in any width with a maximum drop of 6 metres.   Supplied with the Coopers Total Gravity Fail Safe system (TGFS), variable speeds, controlled descent. Developed by Coopers to protect all building types, the SmokeStop Concertina can be applied to atria, escalators, and stairs and will remain hidden within the ceiling until deployed.
